Aluminum Case for Forensic: ISO 17025, DNA, Ballistic
Aluminum Case for Forensic and Crime Scene Investigation Equipment Transport: Evidence Integrity Protection, Chain of Custody Compliance, and ISO 17025 Calibration Stability Engineering
Forensic and crime scene investigation equipment represents one of the most legally sensitive categories of transported instruments in any industry. A single alternate light source (Rofin Flare Plus/Polilight PL500; $8,000-$25,000) that arrives with a misaligned filter wheel can compromise the visualization of latent fingerprints, bloodstain patterns, and body fluid traces at a crime scene. A forensic digital camera system (Nikon D850/Canon EOS R5 with macro lens; $3,000-$15,000) with condensation on the sensor produces images that may be inadmissible under Daubert/Frye evidentiary standards. A DNA collection kit ( sterile swabs, extraction tubes, chain of custody bags) exposed to temperature above 30C can degrade biological evidence, potentially invalidating STR profile results worth $1,000-$5,000 per sample in laboratory analysis costs and irreplaceably compromising a criminal investigation. A digital forensics workstation (Tableau T8u/Logicube Falcon-NEO; $5,000-$25,000) with ESD damage to the write blocker can produce corrupted disk images, rendering digital evidence inadmissible under Federal Rules of Evidence 901(b)(9). A ballistic evidence transport case that allows cartridge cases to contact each other can obliterate microscopic firing pin/breechface marks, destroying the very evidence that links a fired cartridge to a specific firearm. This comprehensive engineering guide examines the forensic transport environment, evidence integrity and chain of custody protection, alternate light source and forensic imaging transport, fingerprint and biometric kit transport, DNA and biological evidence transport, digital forensics equipment transport, ballistic evidence transport, crime scene lighting and measurement equipment transport, regulatory standards (ISO 17025, ASTM E1492, SWGMAT, OSAC, FBI ERT, NIJ), and OEM/ODM solutions for the forensic and crime scene investigation industry.
Forensic Transport Environment Challenges
The forensic transport environment combines evidence integrity requirements, contamination prevention at molecular/biological levels, chain of custody documentation, ESD protection for digital evidence, UV/visible light protection for photosensitive evidence, and temperature/humidity stability for biological samples. These requirements exceed typical industrial case engineering because the consequences of transport damage extend beyond equipment replacement cost to include the potential collapse of a criminal prosecution:
Evidence Integrity and Contamination Protection Requirements
| Environmental Factor | Forensic Requirement | Transport Risk | Case Mitigation |
|---|---|---|---|

| Tamper evidence | Chain of custody per ASTM E1492; FBI ERT SOP | Unauthorized access; evidence substitution | Tamper-evident seal slots; serialized lock; evidence tape anchor points |
Case Materials for Forensic Environment
The forensic environment demands materials that prevent biological contamination, preserve evidence integrity, and maintain chain of custody. The case exterior is 6061-T6 aluminum (anodized per MIL-A-8625 Type III, 25 um hardcoat, resistant to forensic chemicals: cyanoacrylate fuming residue, ninhydrin, DFO, amido black, luminol, gentian violet). The gasket is EPDM (70 Shore A, compression set <25% per ASTM D395, IP65/IP66 rated, operating temperature -40C to +120C, resistant to isopropyl alcohol, methanol, and forensic reagent residues, non-outgassing per ASTM E595 TML <0.5%). Interior foam is closed-cell polyethylene (Ethafoam 220, 33 kg/m3, non-particulating, lint-free, suitable for biological evidence contact, non-absorbent to prevent cross-contamination). For digital forensics compartments, ESD-safe conductive polyethylene foam (R6 grade, surface resistance 10^6-10^9 ohm per IEC 61340-5-1) with grounding snap (10mm stud, 1 megohm resistor) is used. For biological evidence compartments, medical-grade HDPE dividers (FDA 21 CFR 177.1520, chemical-wipeable, autoclave-safe at 121C) separate individual evidence items. Fasteners are 316 stainless steel (crevice-corrosion resistant, A4-70 grade, nylon patch lock). The case features a pressure equalization valve (Gore-Tex membrane, IP66, prevents vacuum seal from trapping moisture and condensation on evidence). A tamper-evident seal system includes serialized evidence tape anchor points (4-point, aluminum reinforced, compatible with standard evidence seals per ASTM E1492). The interior is configured with UV-opaque black foam (blocks 99% of UV-A/UV-B, protects fluorescent and luminescent evidence traces). A temperature data logger (LogTag TRED30-16R, +/-0.5C, NIST traceable) is installed in biological evidence compartments for chain of custody thermal documentation.
Alternate Light Source and Forensic Imaging Transport
Alternate Light Source (ALS) Transport
| Instrument (representative) | Weight (kg) | Value | Transport Risk | Case Design |
|---|---|---|---|---|
| Rofin Flare Plus | 4.0-5.5 | $15,000-$25,000 | Filter wheel misalignment; lamp; fiber optic cable; power supply | 50mm foam, filter wheel lock, lamp cradle, cable compartment, ESD |
| Polilight PL500/PL6 | 3.5-5.0 | $10,000-$20,000 | Filter wheel; LED array; focusing lens; touchscreen | 50mm foam, filter lock, LED protector, screen cover, ESD |
| SPEX Mini-CrimeScope | 3.0-4.5 | $8,000-$15,000 | Lamp housing; filter wheel; power cord; intensity dial | 25mm foam, lamp cradle, filter compartment, dial protector |
| Crime-Lite 80L/82L (Foster+Freeman) | 2.0-3.5 | $3,000-$8,000 | LED array; lens; battery; charger; tripod mount | 25mm foam, LED protector, lens cap, battery compartment |
| TruScan Raman (handheld) | 1.0-1.5 | $25,000-$50,000 | Laser; spectrometer; touchscreen; battery; sample probe | 50mm foam, laser lock, spectrometer cradle, screen protector |
Alternate light source case engineering: The alternate light source is one of the most transport-sensitive forensic instruments. The filter wheel (precision interference filters, 400-700nm bandpass, 10nm FWHM, mounted on a stepper-motor-driven wheel with 8-12 positions) can shift from lateral shock exceeding 10g, causing wavelength misalignment that degrades latent fingerprint visualization. A 2nm wavelength shift can reduce fluorescent dye excitation efficiency by 30-50%, potentially causing missed evidence. The light source (metal halide arc lamp 350W or LED array 50-100W) is sensitive to vibration that can crack the lamp envelope or misalign the LED collimator lens. The fiber optic light guide (silica bundle, 3-8mm diameter, 1-2m length, $500-$2,000) can fracture at the connector from bending stress during transport. The case provides: (1) 50mm closed-cell PE foam on all surfaces for filter-wheel-equipped instruments, 25mm for LED-based units; (2) filter wheel lock (friction clamp preventing wheel rotation during transport); (3) lamp/LED cradle (custom-cut EVA, 5mm contact surface, isolates lamp housing from vibration); (4) fiber optic cable compartment (minimum bend radius 100mm, coiled in 20mm foam channel); (5) power supply compartment (medical-grade isolated, 5mm foam, IEC C13/C14 connector caps); (6) viewing filter set compartment (goggles: orange, yellow, red, clear; 15mm foam slots); (7) tripod carrier slot (aluminum tripod, 2-3kg, strapped to case exterior); (8) ShockWatch 15g label; (9) ESD-safe foam for instrument electronics; (10) IP65 gasket seal; (11) humidity indicator card; (12) desiccant holder (50g silica gel); (13) tamper-evident seal points. For Raman spectrometer transport (TruScan/Thermo FirstDefender), the case includes a laser safety compartment (Class 3B/4 laser, key-locked, interlock cap, radiation warning label per 21 CFR 1040.10).
Forensic Photography and Imaging Transport
| Equipment (representative) | Weight (kg) | Value | Transport Risk | Case Design |
|---|---|---|---|---|
| Nikon D850 + 105mm macro + ring flash | 2.5-3.5 | $4,000-$8,000 | Sensor dust; lens fungus; flash capacitor; shutter | 25mm foam, body cradle, lens slot, flash compartment, sensor cap |
| Canon EOS R5 + RF 100mm macro | 2.0-3.0 | $5,000-$10,000 | Sensor; IBIS; lens; battery; memory card | 25mm foam, body cradle, lens slot, card compartment, ESD |
| Copy stand + lighting (Kaiser/Griot) | 8.0-15.0 | $1,500-$5,000 | Column alignment; light arm; base plate; bulbs | 25mm foam, column cradle, light arm slot, bulb compartment |
| Forensic scale/ruler set (ABFO No.2) | 0.5-1.0 | $50-$200 | Bending; scratch; scale calibration | Rigid flat compartment, 10mm foam, individual slots |
| 3D scanner (Artec Eva/Space) | 1.0-2.0 | $20,000-$50,000 | Structured light projector; dual camera; IMU; touchscreen | 50mm foam, projector cover, camera caps, IMU lock, screen protector |
Forensic photography case engineering: The digital camera sensor (Nikon D850 45.7MP, Canon R5 45MP) is the most transport-sensitive component. A single dust particle on the sensor produces a visible artifact in macro forensic photography, potentially rendering evidence images inadmissible. Condensation on the sensor glass during temperature transitions (e.g., moving from air-conditioned vehicle to humid crime scene) can produce fungal growth within 48 hours if not dried. The macro lens (Nikon Micro-Nikkor 105mm f/2.8, Canon RF 100mm f/2.8L IS) has a precision optical alignment that can shift from impact, reducing image sharpness at 1:1 magnification. The ring flash (Nikon R1C1, Canon MR-14EX II) has electrolytic capacitors (330uF, 330V) that can degrade from vibration, reducing flash recycling time. The case provides: (1) 25mm closed-cell PE foam on all surfaces; (2) camera body cradle (custom-cut EVA, lens mount facing up, 5mm contact, prevents body rotation); (3) lens slot (individual, 10mm foam, rear element cap, front element cap); (4) ring flash compartment (15mm foam, capacitor isolation, battery compartment separate); (5) memory card compartment (anti-static foam, individual SD/CFexpress slots, 5mm foam); (6) forensic scale/ruler compartment (flat rigid slot, 10mm foam, prevents bending); (7) remote shutter release compartment; (8) sensor cleaning kit compartment (rocket blower, sensor swab, cleaning solution, in sealed pouch); (9) copy stand column cradle (for evidence documentation at lab, 25mm foam, column locked against movement); (10) lighting arm compartment (LED panels or strobes, 15mm foam, bulb/LED protectors); (11) ShockWatch 15g label; (12) humidity indicator card; (13) desiccant holder (50g silica gel); (14) IP65 gasket seal. For 3D forensic scanner transport (Artec Eva/Space/Leo), the case provides 50mm foam, structured light projector cover (lens cap + foam), dual camera lens caps, IMU lock (MEMS gyro, sensitive to >10g), touchscreen protector (tempered glass 0.3mm), and calibration board compartment (rigid flat, 15mm foam, reference sphere set).
Fingerprint and Biometric Evidence Kit Transport
Fingerprint Development Kit Transport
| Component (representative) | Weight (kg) | Value | Transport Risk | Case Design |
|---|---|---|---|---|
| Cyanoacrylate fuming wand/kit | 1.0-2.0 | $200-$800 | CA vapor leak; heating element; battery; wand nozzle | 25mm foam, sealed CA compartment, heating element cradle, nozzle cap |
| Fingerprint powder set (black/white/fluorescent) | 0.5-1.5 | $50-$300 | Powder spill; contamination between colors; brush damage | Individual sealed jars, 10mm foam, brush compartment, spill containment |
| Zephyr fiberglass brush set | 0.2-0.5 | $30-$100 | Bristle damage; deformation; contamination | Rigid tube compartments, 10mm foam, individual brush tubes |
| Lift tape and backing cards | 0.5-1.0 | $30-$100 | Adhesive degradation; card bending; temperature | Flat compartment, 10mm foam, temperature insulated, individual card slots |
| Ninhydrin/DFO/1,2-indandione reagent kit | 0.5-2.0 | $100-$500 | Solvent leak; chemical degradation; light exposure | Sealed chemical compartment, UV-opaque foam, spill tray, 15mm foam |
Fingerprint kit case engineering: The fingerprint development kit combines powder, brush, chemical reagent, and lifting components, each with distinct transport requirements. Cyanoacrylate (superglue) fuming compound is volatile (vapor pressure 0.2 mmHg at 25C) and requires a sealed compartment with vapor barrier (aluminum foil-lined, PTFE gasket lid) to prevent CA polymerization on case interior surfaces during transport. The fuming wand/heater (Siralus/BLUESTAR) has a precision nozzle (0.5mm orifice) and heating element (60-80C operating) that can be damaged by impact. Fingerprint powder jars (magnetic, aluminum, fluorescent) must be individually sealed to prevent cross-contamination, which would produce dual-color dusting artifacts. The fiberglass brush (Zephyr, tapered fiberglass bristles, 0.07mm diameter) is extremely fragile; bristle deformation from compression destroys the brush ability to deposit powder evenly. The case provides: (1) 25mm closed-cell PE foam; (2) CA fuming compound compartment (sealed, PTFE gasket lid, vapor barrier, 15mm foam); (3) powder jar compartments (individual sealed HDPE containers, 10mm foam, spill containment tray); (4) brush compartments (rigid PVC tubes, 10mm foam, bristles uncompressed); (5) lift tape compartment (flat, temperature-insulated, 10mm foam, individual card slots, 100 lift tape + 100 backing cards); (6) chemical reagent compartment (ninhydrin in heptane, DFO in HFE, 1,2-indandione; sealed glass bottles in foam, UV-opaque, spill tray); (7) magnetic wand/powder compartment (magnetic powder, applicator wand, 15mm foam); (8) hinge lifter compartment (silicone rubber, 10mm foam, flat); (9) ShockWatch 25g label; (10) IP65 gasket seal; (11) humidity indicator; (12) desiccant holder; (13) tamper-evident seal points; (14) chemical spill kit (absorbent pad, neutralizer, in sealed pouch). The case interior is designed for decontamination: all foam surfaces are removable for replacement, HDPE surfaces are chemical-wipeable with isopropyl alcohol, and the case drains through a sealed port for liquid spill cleanup.
DNA and Biological Evidence Transport
Biological Evidence Collection Kit Transport
| Component (representative) | Weight (kg) | Value | Transport Risk | Case Design |
|---|---|---|---|---|
| Sterile DNA swab kit (Puritan/BD) | 0.3-0.5 | $50-$200 | Contamination; swab tip contact; tube seal; temperature | Individual sealed compartments, 15mm foam, temperature logger, chain of custody |
| Blood stain collection kit | 0.5-1.0 | $100-$300 | DNA degradation; stain card moisture; temperature above 30C | Insulated compartment, 25mm PU foam, cold pack slot, temp logger, HDPE |
| Sexual assault evidence kit (SAEK) | 1.0-2.0 | $200-$500 | Cross-contamination; chain of custody; temperature; swab integrity | Sealed compartment, tamper-evident, 25mm foam, temp logger, individual slots |
| Reference sample collection kit | 0.3-0.5 | $50-$150 | Contamination; buccal swab contact; tube label | Individual sealed slots, 15mm foam, label pocket |
| Tissue/bone sample transport | 0.5-2.0 | $100-$500 | Putrefaction; fluid leak; temperature; biohazard | Sealed biohazard compartment, 25mm foam, cold pack, absorbent, biohazard label |
Biological evidence case engineering: Biological evidence transport is governed by the principle that DNA degrades irreversibly above 30C, with rapid degradation above 37C. The swab (Puritan HydraFlock 6-inch sterile swab, or BD Franklin swab) must arrive with the collection tip uncontaminated, which requires a sealed tube compartment preventing contact with any surface. Blood stain cards (Fitzco/Whatman FTA card, 4×6 inch) must remain dry; moisture activates embedded chemicals and degrades the DNA sample. The chain of custody documentation (per ASTM E1492 and FBI ERT SOP) requires a tamper-evident seal system that records every access point. The case provides: (1) individual sealed evidence compartments (HDPE, medical-grade, FDA 21 CFR 177.1520, chemical-wipeable, autoclave-safe at 121C); (2) swab tube compartments (individual, 15mm foam, tube cap locked against opening, tip-up orientation preventing contact with tube wall); (3) blood stain card compartment (flat, rigid, 25mm PU foam insulation, cold pack slot adjacent maintaining 2-8C for up to 8 hours, temperature data logger LogTag TRED30-16R +/-0.5C NIST traceable recording at 5-minute intervals); (4) SAEK compartment (sealed, tamper-evident evidence tape anchor points at 4 corners, 25mm foam, individual item slots for 7 swab tubes, 2 slides, 1 comb, 1 envelope, 1 instruction sheet); (5) biohazard containment compartment (sealed, absorbent pad, biohazard symbol label per 29 CFR 1910.1030, 25mm foam, cold pack slot); (6) chain of custody form pocket (waterproof sleeve, external access without opening evidence compartment); (7) cold pack compartment (2x 200g gel ice pack, HDPE container, separated from evidence by HDPE barrier); (8) temperature data logger compartment (external display, waterproof, NIST traceable certificate pocket); (9) ShockWatch 25g label; (10) IP66 gasket seal (prevents moisture ingress and cross-contamination); (11) humidity indicator card (30-50% RH range); (12) desiccant holder (100g silica gel, sealed to prevent contact with evidence); (13) tamper-evident seal system (4-point serialized evidence tape anchors, compatible with standard evidence seals per ASTM E1492); (14) biohazard label (exterior, per OSHA 29 CFR 1910.1030); (15) UV-opaque interior (blocks 99% UV-A/UV-B, protects fluorescent evidence). For tissue/bone sample transport, the case includes a sealed biohazard container (HDPE, 500ml, with absorbent pad and secondary containment per IATA Category B UN3373 packaging instruction P650).
Digital Forensics Equipment Transport
Write Blocker and Forensic Workstation Transport
| Equipment (representative) | Weight (kg) | Value | Transport Risk | Case Design |
|---|---|---|---|---|
| Tableau T8u (USB 3.0 write blocker) | 0.3-0.5 | $500-$900 | ESD; connector; FPGA; power supply | ESD-safe foam, 25mm, connector caps, power compartment, grounding |
| Logicube Falcon-NEO (drive duplicator) | 2.0-3.5 | $5,000-$15,000 | ESD; HDD dock; touchscreen; battery; SAS/SATA | 50mm foam, ESD-safe, dock cover, screen protector, battery compartment |
| WiebeTech Ultradock (read/write) | 0.5-1.0 | $200-$500 | ESD; connector; power; dock pins | ESD-safe foam, 25mm, connector caps, dock pin protector |
| Forensic laptop (Panasonic Toughbook) | 2.5-3.5 | $3,000-$6,000 | SSD/HDD; screen; shock; vibration; ESD | 50mm foam, ESD-safe, screen protector, battery compartment, ruggedized |
| Cellphone extraction kit (Cellebrite) | 1.5-3.0 | $10,000-$25,000 | ESD; connector set; cable; touchscreen; software dongle | 50mm foam, ESD-safe, cable compartments, screen protector, dongle slot |
Digital forensics case engineering: Digital forensics equipment is governed by Federal Rules of Evidence 901(b)(9), which requires that the process of producing electronic evidence be shown to produce an accurate result. A write blocker (Tableau T8u, USB 3.0, hardware-based, FPGA-controlled) must arrive with its write-blocking function intact; ESD damage to the FPGA (Xilinx Spartan, 0.5um process, ESD sensitivity 2000V HBM) can cause silent write-blocking failure, allowing the forensic examiner to inadvertently modify the source evidence and rendering it inadmissible. The drive duplicator (Logicube Falcon-NEO, 3GB/min, 4x SATA/SAS) has a precision HDD dock connector (SFF-8087, 36-pin, gold-plated, 0.5mm pitch) that can be damaged from lateral shock, causing intermittent contact during imaging. The forensic laptop SSD (NVMe, PCIe Gen4, M.2 2280) can suffer NAND cell damage from ESD, corrupting the forensic acquisition software and case database. The case provides: (1) 50mm closed-cell PE foam for duplicators and laptops, 25mm for write blockers; (2) ESD-safe conductive foam (R6 grade, surface resistance 10^6-10^9 ohm per IEC 61340-5-1) on all electronic component contact surfaces; (3) grounding snap (10mm stud, 1 megohm resistor to ground, wrist strap compatible); (4) write blocker cradle (ESD-safe foam, connector caps for USB 3.0, SATA, SAS, power; 5mm contact surface); (5) drive duplicator cradle (50mm foam, HDD dock cover, touchscreen protector 0.3mm tempered glass, battery compartment isolated); (6) cable compartment (SATA, SAS, USB-C, Lightning, USB-micro; individual coiled in 15mm foam channels); (7) software dongle compartment (anti-static foam, individual slots, 10mm foam); (8) forensic laptop compartment (50mm foam, ESD-safe, screen protector, keyboard cover, battery compartment separate for Li-ion 11.1V); (9) cellphone extraction kit compartment (50mm foam, ESD-safe, connector set compartment, touchscreen protector, software dongle slot); (10) anti-static bag supply (500x600mm, 100 count, in sealed pouch); (11) ShockWatch 15g label; (12) IP65 gasket seal; (13) humidity indicator card; (14) desiccant holder (50g silica gel); (15) tamper-evident seal points. The ESD-safe foam is verified at 10^6-10^9 ohm surface resistance per IEC 61340-5-1 using a megohmmeter (Prostat HVC-MK2) before each deployment.
Ballistic Evidence Transport
Cartridge Case and Bullet Evidence Transport
| Evidence Type | Dimensions | Weight | Transport Risk | Case Design |
|---|---|---|---|---|
| Fired cartridge cases (.22LR to .50BMG) | 15-70mm length, 5-20mm diameter | 1-20g each | Breechface mark damage; firing pin impression; extractor mark | Individual HDPE tubes, 15mm foam, foam end caps, partitioned |
| Fired bullets (complete) | 10-30mm length, 5-12mm diameter | 2-30g each | Land and groove impression; striation damage; bullet tip deformation | Individual HDPE tubes, foam-lined, 15mm foam, orientation marker |
| Shotshell (fired) | 65-75mm length, 18-20mm diameter | 10-20g each | Extracting mark; firing pin; plastic body deformation | Individual tubes, 15mm foam, rigid |
| Firearm evidence (handgun/long gun) | 150-1000mm length | 0.5-5.0 kg | Breechface; firing pin; barrel; trigger; serial number | Custom cradle, 50mm foam, locked, chain of custody, trigger guard |
| Trace evidence (GSR, primer residue) | SEM stubs, swabs | <10g each | Particle loss; contamination; temperature; humidity | Sealed SEM stub compartments, 15mm foam, ESD-safe, temp controlled |
Ballistic evidence case engineering: Ballistic evidence is uniquely sensitive because the microscopic marks on a fired cartridge case or bullet (firing pin impression, breechface marks, extractor mark, ejector mark, chamber marks, land and groove impressions, striations) are the forensic signature that links a fired component to a specific firearm. Physical contact between two cartridge cases during transport can obliterate or create false marks, potentially producing a false positive or false negative identification. The case provides: (1) individual HDPE tubes for each cartridge case and bullet (sealed, foam end caps, 15mm foam between tubes, orientation marker showing which end is the breechface); (2) partitioned compartment layout (prevents any contact between evidence items, even under ASTM D4169 DC-13 transport shock); (3) fired bullet cradle (HDPE V-block, foam-lined, prevents any contact with rifling surface); (4) shotshell compartment (individual rigid tubes, prevents plastic body deformation); (5) firearm evidence cradle (custom-cut 50mm foam, trigger guard locked open, barrel supported at 2 points, serial number area accessible without removal, chain of custody tag attachment point); (6) GSR/trace evidence compartment (sealed SEM stubs in individual containers, ESD-safe, temperature-stable, 15mm foam); (7) evidence label pocket (waterproof, external access); (8) chain of custody form pocket (waterproof sleeve); (9) ShockWatch 25g label; (10) IP66 gasket seal (prevents moisture corrosion on metal evidence); (11) tamper-evident seal system (4-point serialized evidence tape); (12) humidity indicator card; (13) desiccant holder (50g silica gel). The interior foam is lint-free closed-cell PE (Ethafoam 220, 33 kg/m3, non-particulating) to prevent fiber contamination of trace evidence. The HDPE tubes are transparent for visual evidence identification without opening, and each tube has a label slot (chain of custody number, evidence description, collection date, collector ID per ASTM E1492).
Crime Scene Measurement and Documentation Transport
Crime Scene Measurement and Mapping Equipment Transport
| Equipment (representative) | Weight (kg) | Value | Transport Risk | Case Design |
|---|---|---|---|---|
| Leica BLK360 3D laser scanner | 1.0-2.0 | $20,000-$40,000 | Scanner mirror; motor; IMU; camera; touchscreen | 50mm foam, scanner lock, lens caps, screen protector, ESD |
| Faroe Focus laser scanner | 2.0-3.0 | $15,000-$40,000 | Mirror; motor; touchscreen; battery; camera | 50mm foam, mirror cover, screen protector, battery compartment |
| Trimble/Rollei total station (crime scene) | 5.0-6.5 | $15,000-$45,000 | Encoder; EDM; compensator; motor; display | 50mm foam, motor lock, lens caps, screen protector, tripod carrier |
| Bloodstain pattern analysis kit | 1.0-2.0 | $200-$800 | Calibrated string; protractor; ruler; calculator; photographic | 25mm foam, string compartment, ruler slot, calculator cradle |
| Trajectory rod kit (7.62mm/9mm) | 1.0-2.0 | $100-$400 | Rod bending; centering washer loss; probe tip damage | Rigid tube compartments, 25mm foam, washer compartment, tip protectors |
Crime scene measurement case engineering: The 3D laser scanner (Leica BLK360, Faro Focus) is the most transport-sensitive crime scene documentation instrument. The scanner mirror (rotating polygon, 9500 RPM, 360 degree/s horizontal, 300 degree/s vertical, +/-0.6mm at 10m accuracy) can shift from lateral shock exceeding 10g, degrading scan registration accuracy. The IMU (MEMS, 200 Hz, 0.1 degree drift) in the BLK360 can lose calibration from impact, affecting the scan-leveling accuracy. The total station (Trimble/Rollei, used for crime scene mapping) has an absolute angular encoder (0.5 arc-second resolution) and EDM (+/-1mm+2ppm) that can lose calibration from shock. Trajectory rods (6mm diameter aluminum, 90-120cm length, with centering washers and 7-degree tapered probe tips) must arrive straight; even 0.5mm bend introduces 1 degree angular error at 3m reconstruction distance. The case provides: (1) 50mm closed-cell PE foam on all surfaces; (2) scanner cradle (custom-cut EVA, 5mm contact, scanner lock preventing mirror rotation, lens caps for 3 cameras, touchscreen protector 0.3mm tempered glass); (3) scanner battery compartment (Li-ion 14.4V 5.2Ah, isolated in 10mm foam); (4) total station cradle (50mm foam, motor lock, telescope lens cap, EDM lens cap, compensator lock, screen protector); (5) tripod carrier slot (strapped to case exterior, 5-7kg carbon fiber); (6) trajectory rod compartment (rigid PVC tubes, individual, 25mm foam, prevents bending, centering washer compartment, tip protector caps); (7) bloodstain pattern analysis kit compartment (25mm foam, calibrated string spool, protractor, rigid rulers, scientific calculator, photographic scale set); (8) ShockWatch 15g/25g label; (9) IP65 gasket seal; (10) humidity indicator; (11) desiccant holder; (12) ESD-safe foam for scanner electronics; (13) tamper-evident seal points.

Compliance engineering: The forensic case must support the laboratory ISO 17025 quality management system by ensuring that transported instruments arrive with calibration intact and that evidence arrives free of contamination. The chain of custody system (tamper-evident seals, serialized labels, evidence tape anchor points) must comply with ASTM E1492, which requires that evidence be stored and transported in a manner that preserves its integrity and prevents unauthorized access. The ESD protection system (conductive foam, grounding snap, anti-static liner) must comply with IEC 61340-5-1, which specifies ESD control requirements for electronic components with sensitivity thresholds as low as 100V HBM. The transport qualification testing (ASTM D4169 DC-13, ISTA 3A) must demonstrate that the case protects instruments and evidence through the distribution cycle (truck, air, hand carry, forklift). The biological evidence containment system (sealed compartments, absorbent pads, biohazard labels) must comply with OSHA 29 CFR 1910.1030 (bloodborne pathogens) and IATA DGR UN3373 P650 (Category B biological substance air transport).
