Qosina part number 28700 is a high-performance fluid storage and transfer bag chamber ideal for upstream and downstream bioprocessing applications. Manufactured with medical-grade Renolit 9101 film, a multilayer film composed of high-purity biocompatible polyethylene (PE) contact layer with internal ethylene vinyl alcohol (EVOH) oxygen barrier, this film provides superior clarity, flexibility, strength, chemical resistance, stability in a temperature range of -45°C to 60°C and an extremely low extractables and leachables profile. It features a TruFLO port design, made of POE, which facilitates optimized edge-seal integrity and superior flow rates. This bag includes a robust PP hanging grommet for improved handling.

Qosina offers an extensive line of Check Valves, available in a variety of styles that are in stock and ready for immediate delivery. Qosina part # 80393 features a clear, 0.138 inch OD tubing port inlet and a blue, 0.138 inch OD tubing port outlet. Made of polycarbonate and silicone, this in-line valve and has a low, 0.25 psi cracking pressure, determining when the component starts to open and can withstand 45 psi of back pressure. Qosina offers a variety of flow rates, materials, cracking pressure and back pressure options. Check Valve sample kits are also available which are ideal for testing.
