4-Slot Absorbent Sleeve for UN3373 Leak-Proof Biohazard Bag Bio Specimen Bag
Water absorption rate is an important indicator to measure the water absorption capacity of absorbent materials. 4 Slot Absorbent Pocket Sleeve uses highly absorbent materials and combines them with a porous structure design to achieve a very high water absorption rate. This sleeve uses high-absorbency porous material, soaking up liquids in 30 seconds to reduce contamination risks during transport. Ideal for clinical trial sample shipping, it helps labs efficiently manage bio-specimens
Product Parameters
Product Details
Four-compartment absorbent bags are a safe packaging solution specifically designed for transporting biohazardous materials classified as UN 2814, UN 2900, and UN 3373. Meets IATA/ICAO standards, 95 kPa pressure-tested certification (third-party report available upon request). Suitable for UN 3373 biohazard substances, including viral and bacterial samples,These bags are usually made of high-quality polyethylene materials with good chemical resistance and durability, which can effectively prevent leakage and contamination.
When handling these biohazardous materials, make sure to use appropriate personal protective equipment (PPE), such as gloves, masks, and protective clothing to prevent direct contact. At the same time, follow all applicable safety regulations and operating procedures to ensure personnel safety and environmental protection.
The Sleeves can be produced in our brand name or ai650 ® or in OEM brands or customized labels of customers.
