How do you actually order biological-specimen-carrier top 10 from a Chinese factory? Inquiry, quote, sample, deposit, production, QC, balance, ship. It sounds simple. The 5 steps below are what we actually do.
Below is the catalog data for biological-specimen-carrier top 10. Each model has outer dimensions (in mm), inner cavity (mm), empty weight (g), and material specification. Material is engineering PP or PP+GF for impact resistance. Foam set is included: 25mm base + 10mm lid convoluted.
| Model | Outer (mm) | Inner (mm) | Weight (g) | Material | Size Class |
|---|---|---|---|---|---|
| WL2305 | 230×180×45 mm | 225×150×40 mm | 240 g | PP+PC | First Aid Kit |

The most common model for "biological-specimen-carrier top 10" buyers is the WL2305 (230×180×45 mm OD, 240 g empty weight, PP+PC body).
Shell material for biological-specimen-carrier top 10 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.
We maintain 200+ foam-cut reference designs for biological-specimen-carrier top 10, covering camera bodies, drone kits, broadcast gear, military equipment, medical devices, and industrial tools. Send us your equipment list, we will match to the closest reference or draft a new layout free within 24 hours.
When evaluating biological-specimen-carrier top 10 options, focus on three metrics: (1) Foam density — cheap cases use 15 kg/m³ foam that bottoms out; ours is 25 kg/m³, 5+ year use. (2) Latch cycle rating — cheap plastic latches break after 200 cycles; ours is metal-reinforced, 5,000 cycles. (3) IP certification — every batch ships with serialized IP test certificates.
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.
Ordering biological-specimen-carrier top 10 is 5 steps: inquiry (12h response), quote (with recommendation), PO + 30% deposit, production (35 days + QC photos), balance payment + shipment. Repeat orders are 15-20 days. Custom OEM/ODM adds 25-30 days for mold.
We have 150+ custom design cases since 2014. Whatever your question is, we have probably seen it before.

We can re-cut foam for the same case. Cost: $20-50 per foam set depending on size. Lead time: 5-7 days. We keep your foam layout in our database for 3 years for easy re-order. If equipment changes significantly, you may need a different WL series.
Yes, custom colors available for orders >500 units. Color match to Pantone / RAL: $300 color matching fee, 7-10 days. Standard colors (black, gray, olive, orange) ship with no extra cost and 25-30 day lead time.
We use injection molding exclusively — denser walls, tighter tolerances, better IP rating. Blow molding produces hollow cases with thinner walls (1-2mm), cheaper, but not suitable for IP67 or MIL-STD-810H drop test. If a supplier offers 'injection' at 1/3 our price, it is likely blow-molded.
Yes for DDP and CIF. For FOB or EXW, we ship to a commercial port or address with customs broker. Residential delivery in some regions (EU, USA) requires a local broker to handle customs clearance.
