Flex4Sure™ 3D Bags

Flex4Sure™ 3D Bags are 100-1000L multi-layer PE ‘bag in box’ for the storage and handling of biopharmaceutical process solutions.

The multi-layer co-extrusion film used for the 3D bags ensures minimized gas permeability, good physical strength, and wide chemical compatibility and biocompatibility of the aseptic storage bags, so that they can be safely used for the storage and transportation of various biopharmaceutical liquids. The standard 3D bags are available in chamber volumes from 100L - 1000L and can be used with a corresponding rigid tote for storage of buffers, culture media, intermediates, or drug substances. Luer connectors, CPC quick connectors, sanitary Tri-clamp connectors, or sterile connectors are available for inlet and outlet tubing and filter capsules to ensure compatibility with upstream and downstream process equipment. A variety of sampling tools can be used, such as needleless samplers, Luer female connectors, and medical heparin caps.
