Skip to contentDetailed specs for Large nucleic-acid-case Wholesale from KeXinMaterials source factory. Outer/inner dimensions in mm/inch, weight, material, foam options. Compare WL2305 series. MOQ 30. 12h quote, 35-day delivery.
Spec sheets for Large nucleic-acid-case Wholesale are not always easy to read. Outer vs inner dimensions, weight empty vs loaded, foam density vs foam thickness — buyers in 47 countries ask us about these every week. Here is the honest, real-catalog data.
For Large nucleic-acid-case Wholesale, the WL series splits into Small (WL1204-1504), Medium (WL1905-2808), and Large (WL3812-5020). Within each tier, 2-3 models vary in width and depth. We help you choose during the 12h quote consultation, but the table below is the reference.
| 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 |
| WL3812 | 380×320×120 mm | 365×280×110 mm | 1100 g | PP+PC | Vaccine Carrier |
| WL5020-D | 500×400×200 mm | 480×360×185 mm | 2400 g | PP+PC+VIP | Cold Chain 96h (2-8°C) |
The most common model for "Large nucleic-acid-case Wholesale" buyers is the WL2305 (230×180×45 mm OD, 240 g empty weight, PP+PC body).
All Large nucleic-acid-case Wholesale cases use engineering-grade polypropylene (PP) or PP+glass-fiber composite (PP+GF) for the shell, with CNC-cut closed-cell PE foam inside (density 25 kg/m³). The foam density is calibrated to absorb 1.2m drops on concrete while keeping your equipment from shifting.
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.
In 2024, we shipped Large nucleic-acid-case Wholesale for: (1) Film production — ARRI Alexa Mini + accessories in custom foam. (2) Drone operators — DJI Mavic 3 + RC + 6 batteries. (3) Broadcast — RED Komodo + 2 lenses + monitor. (4) Military — rifles + scopes + ammo. (5) Medical — first aid kits + AED.
Cheap Large nucleic-acid-case Wholesale: $3-8/unit, 6-month lifespan, 200-cycle latch, 15 kg/m³ foam. Our Large nucleic-acid-case 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.
