The most common model for "Anti-static biological-specimen-carrier Wholesale" buyers is the WL2305 (230×180×45 mm OD, 240 g empty weight, PP+PC body).
Shell material for Anti-static biological-specimen-carrier Wholesale is selected per use case: standard PP for general purpose, PP+GF for heavy-duty (10% glass fiber improves impact strength by 35%). Foam is 25 kg/m³ closed-cell PE, 0.5mm CNC cut tolerance. Anti-static ESD foam (10^6-10^11 Ω) available for electronics.
The shell is rated IP67 ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 1.5m). Temperature range is -80 ~ +50 (depending on PCM/VIP configuration) °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.
Here are 3 real Anti-static biological-specimen-carrier Wholesale foam layouts from 2024-2026: (A) Sony A7 IV + 24-70mm + 70-200mm + 3 filters + 2 batteries — fits WL2808. (B) DJI Mavic 3 + RC + 4 batteries + charger — fits WL2005. (C) RED Komodo + 2 lenses + monitor + cables — fits WL5020. We share these at the 12h quote stage.
Cheap Anti-static biological-specimen-carrier Wholesale: $3-8/unit, 6-month lifespan, 200-cycle latch, 15 kg/m³ foam. Our Anti-static biological-specimen-carrier Wholesale: $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.

Yes. Silver-ion anti-microbial additive in the PP compound, effective against 99.9% of bacteria per ISO 22196. Common in medical cases. Adds $1.50-3 per unit depending on size. Lead time +5 days.
UV-resistant: UV-stabilized PP compound, ASTM G154 500-hour tested, ΔE < 2.0 after exposure. Fire-retardant: UL94 V-0 rated material, no toxic flame retardants. Both add $1-3 per unit, 5-day additional lead time.
Standard: 3.0-3.5mm. Thinnest: 2.0mm (with reduced drop rating). Thickest: 5.0mm (with reinforced ribbing). Wall thickness <2.0mm requires special tooling. We optimize wall thickness per use case during the DFM review.
Standard foam: 3-axis CNC, 0.5mm tolerance, ±0.2mm cut precision. 5-axis foam: 0.3mm tolerance, for complex cavities (lenses, irregular shapes, multiple small items). Adds 3-5 days lead time, $5-15 per foam set premium.
Stock modifications: 15-20 days. New mold: 25-30 days after design approval, plus 5-7 days for sample. Full process: 30-40 days from spec confirmation to first production batch. We expedite (10-15 days) for orders >5,000 units with surcharge.
