C-FLEX® Biopharmaceutical tubing

C-Flex® is the original patented thermoplastic elastomer tubing specifically designed to meet the critical demands of pharmaceutical and biopharmaceutical applications for fluid processing.

C-Flex® tubing for Biopharma Manufacturing is specifically designed for aseptic welding connections and sealing disconnection. C-Flex is suitable for sterilization by gamma irradiation and autoclave. It is moldable, bondable and formable, ideal for single-use assemblies, overmolds, and tubing with bags manifolds. 

C-Flex® tubing is manufactured from pharmaceutical-grade thermoplastic elastomer, is fully characterized, validated and tested to a variety of specifications. Extensive biological, chemical, physical properties and extractable testing is available to assist in the validation of C-Flex applications.
