Skip to main contentMIL-SPEC geological-sampling-box from KeXinMaterials source factory. OEM/ODM, wholesale, factory-direct pricing. 9 WL series sizes WL1204-WL5020, IP67/MIL-STD-810H certified, MOQ 30, 12h quote, 30-day delivery to 47 countries.
IP67, MIL-STD-810H, ROHS, CE — the alphabet soup on MIL-SPEC geological-sampling-box marketing pages can be overwhelming. This page cuts through the noise. We publish every test result and every certificate we hold.
If you have not worked with the WL series before, this is the cheat sheet. WL1204-WL1504 are Small (under 200mm). WL1905-WL2808 are Medium (200-300mm). WL3812-WL5020 are Large (300-500mm). Within each tier, the model number encodes the length, width, height in cm.
| Model | Outer (mm) | Inner (mm) | Weight (g) | Material | Size Class |
|---|---|---|---|---|---|
| WL2305 | 230×180×45 mm | 225×150×40 mm | 240 g | PP | Multimeter / Caliper |
| WL2808 | 275×230×82 mm | 265×190×76 mm | 480 g | PP+AS | Surveying Total Station |
| WL5020 | 500×400×200 mm | 480×360×185 mm | 2400 g | PP+AS | Optical Microscope |
The most common model for "MIL-SPEC geological-sampling-box" buyers is the WL2305 (230×180×45 mm OD, 240 g empty weight, PP body).
Cheap protective cases use 15 kg/m³ foam that bottoms out after 6 months. Our MIL-SPEC geological-sampling-box uses 25 kg/m³ foam rated for 5+ year use. The difference is in the cell structure: 25 kg/m³ cells rebound after compression, 15 kg/m³ cells do not. We have tested both. The cheaper foam fails.
The shell is rated IP67 ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 1.2m). Temperature range is -40 ~ +80 °C. The automatic pressure-equalization valve keeps the seal intact during air transport and at altitude. Latch is a double-throw design rated for 5,000 open/close cycles. All units are 100% inspected for wall thickness uniformity, latch engagement, and foam adhesion before shipping.
Our MIL-SPEC geological-sampling-box buyers in 2024 include: 35% camera operators / filmmakers, 25% drone pilots / commercial UAS, 15% broadcast / TV stations, 10% military / law enforcement, 10% medical / first responders, 5% industrial / OEM. Profile data from 2024 buyer survey.
Cheap MIL-SPEC geological-sampling-box: $3-8/unit, 6-month lifespan, 200-cycle latch, 15 kg/m³ foam. Our MIL-SPEC geological-sampling-box: $5-15/unit, 10-year lifespan, 5,000-cycle latch, 25 kg/m³ foam. Over 5 years, our case is 4-5x cheaper per year of use. Total cost of ownership wins.
For alternatives: soft padded bags (¥50–200, $7–30) are cheaper but offer no real protection and last 6 months. Aluminum hard cases ($80–300) are heavier, prone to denting, and 2–4× the price. Carbon fiber cases ($300+) are overkill for 95% of B2B use cases. Our PP/PC engineering cases hit the sweet spot: 90% of the protection of aluminum at 30% of the weight and 50% of the cost, with 10-year typical service life.

MIL-SPEC geological-sampling-box: Lab Test Certificate Reference
Visual summary of the key specifications. Print-friendly for buyer reference.
📹 60-second factory + product walkthrough. MIL-SPEC geological-sampling-box lab test footage: water submersion, drop test, temperature chamber
5-stage QC: 100% surface resistance / dimensional check, 26 drops at 1.2m + water submersion, -40 to +80°C × 12 cycles, 5,000 latch cycles, 1,000 pressure valve cycles. Lot certificates traceable by serial number.
Both protect against dust (6 = dust-tight). IP67 = submersible 1m / 30 min. IP68 = submersible beyond 1m (typically 3-5m) / continuous. IP68 costs ~15% more due to reinforced seals and pressure valves.
ASTM B117 standard, 96 hours continuous salt spray (5% NaCl solution at 35°C). After 96 hours, no visible corrosion on metal parts, no delamination of surface coating. Standard for all outdoor-rated models.
UV exposure test per ASTM G154: 500 hours accelerated UV exposure (UVA-340 lamp, 60°C). After 500 hours, color shift ΔE < 2.0, no cracking, no chalking. Suitable for outdoor storage and direct sun exposure.
Anti-static foam option: surface resistance 10^6 to 10^11 Ω per ANSI/ESD S541. Standard foam is non-ESD. If you are transporting electronics (camera bodies, circuit boards, hard drives), specify anti-static foam.
Free 5-day prototyping. ISO 9001 factory-direct. Ships to 47 countries.
