C-Flex® is a unique, patented thermoplastic elastomer specifically designed to meet the critical demands of the pharmaceutical, research, biopharmaceutical and diagnostics industries. C-Flex® biopharmaceutical tubing has been used by many of the world’s leading biotech and pharmaceutical processing companies.

• Non-pyrogenic, non-cytotoxic, non-hemolytic
• Chemically resistant to concentrated acids and alkalis
• Low platelet adhesion, low protein binding
• Ultra-smooth inner bore
• Available in clear or opaque formulations
• Lot traceable, safe disposal through incineration

Each coil of C-Flex tubing is extruded to precise Int.Ø, Ext.Ø.
