Spec sheets for Large doctor-diagnostic-bag 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.
We do not round dimensions. We do not approximate. Every line in this table is the real catalog data for Large doctor-diagnostic-bag Wholesale, measured on the production line, with QC sign-off and lot certificate. This is the data we ship with every order.
| 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 |
| WL6030-O | 600×450×300 mm | 575×420×280 mm | 4200 g | PP+PC+VIP | Organ Transport |
The most common model for "Large doctor-diagnostic-bag Wholesale" buyers is the WL2305 (230×180×45 mm OD, 240 g empty weight, PP+PC body).
Cheap protective cases use 15 kg/m³ foam that bottoms out after 6 months. Our Large doctor-diagnostic-bag Wholesale 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 1.5m). 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 doctor-diagnostic-bag 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.
Top 5 mistakes we see in 2024: (1) Over-specifying size — buying WL5020 when WL3812 fits. (2) Choosing by price alone. (3) Skipping IP certification. (4) Ignoring latch type. (5) Not requesting lot certificates. All five add up to a 2-3x higher TCO over 5 years.
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 Large doctor-diagnostic-bag Wholesale 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.
Our spec sheets include the manufacturing tolerance, not just the nominal value. That is what real engineers ask for.
