M-Flex™ TPE Tubing

M-Flex™ – Meissner’s Solution to the industry’s TPE Tubing Shortage

M-Flex™ provides an immediately available thermoplastic elastomer (TPE) tubing solution that mitigates manufacturing delays caused by shortages in TPE tubing used in biopharmaceutical applications. Backed by Meissner’s robust and secure supply chain, this TPE tubing helps mitigate risk in manufacturing operations.

By benchmarking TPE tubing commonly used in biopharma, Meissner’s team of SME’s was able to produce a material and component design space for M-Flex™ that allows for direct substitution in single-use assemblies.  A comprehensive Qualification Guide provides test data that substantiates M-Flex™ tubing’s welding, sealing and pumping equivalency, and helps to expedite our client’s internal qualification process.

M-Flex™ has been tested extensively for biocompatibility in accordance with USP and ISO standards.  It meets the requirements as specified in the current USP Class VI plastics tests and is non-cytotoxic.

M-Flex™ tubing is a critical component of Meissner’s BioLink® assemblies. BioLink® modular overmolding incorporates overmolded unitized end fittings with lengths of M-Flex™ tubing and polypropylene modules to deliver next generation connectivity and increased process robustness.  These secure connections can even incorporate filters and single-use gauge tees.

For assistance in exploring an immediately available, substantially equivalent TPE tubing option, with a secure supply chain, please contact Meissner.  We understand the urgency created by alternative TPE options, and we are dedicated to helping you reduce risk in your manufacturing operations.
