2D Bag Solutions

Flex4Sure™ 2D Bag Systems incorporate chambers manufactured from INFUFLEX film from Renolit. This co-extruded film has a PE contact layer and offers robustness, a well-characterized extractable profile, high clarity, and excellent chemical resistance. In sizes from 250ml to 50L, Flex4Sure™ 2D Bag Systems are well suited for storing and transporting fluids used in biopharmaceutical manufacturing. Standard Flex4Sure™ 2D Bags are available with Cellgyn® TPE tubing and MPC connectors for rapid delivery or can be integrated into custom assemblies designed to meet your application.
