What 3M does

Solventum, operating the legacy 3M™ Membrana™ medical membrane materials franchise, designs and manufactures specialized capillary membranes from engineered synthetic polymers for integration into medical devices. Its product portfolio spans three primary clinical use cases: blood oxygenation in cardiac surgery and extracorporeal support (OXYPLUS™, OXYPHAN™, X30, HEXPET™), hemodialysis and hemodiafiltration (DIAPES™, PUREMA™, SYNPHAN™), and therapeutic apheresis and plasma fractionation (SYNCLEAR™, MicroPES™ TF10, PLASMAPHAN™, FractioPES™). Each membrane family is engineered with specific pore structures — including asymmetric, sponge-like, and thermally induced phase separation polypropylene architectures — to deliver defined sieving coefficients, biocompatibility, and endotoxin barrier performance tailored to OEM device requirements. Capabilities include customer-specific membrane manufacturing alongside standard product lines.

The business operates a pure OEM/embedded B2B go-to-market, selling membrane materials directly to medical device manufacturers and integrators rather than to end clinical customers. GTM is quote-based via an 'Ask an expert' inquiry form that segments inquiries by OEM/integrator, distributor, end user, or engineering firm, supplemented by an authorized distributor network and a technical resources library of product data sheets and ISO certificates. Pricing is not publicly disclosed. The unit serves global medical device OEMs across more than 35 countries in North America, LATAM, Europe, APAC, the Middle East, and Africa.

Ownership has undergone two consecutive restructurings in an 18-month window. The business originated inside 3M's Health Care segment, was spun off into Solventum in 2024, and the broader Purification and Filtration Business — including these medical membrane materials — was acquired by Thermo Fisher Scientific in 2025. The Wuppertal, Germany facility associated with the Membrana brand employs approximately 120 people.

Core offering

3M (Membrana division, now part of Solventum / acquired by Thermo Fisher Scientific in 2025) manufactures and sells specialized capillary membranes under the 3M™ Membrana™ brand for OEM integration into medical devices. The portfolio spans blood oxygenation membranes for cardiac surgery and respiratory therapies, hemodialysis membranes for blood purification, and therapeutic apheresis membranes for plasma separation and fractionation. Products are engineered from synthetic polymers with tailored separation profiles, biocompatibility, and chemical resistance for extracorporeal blood processing devices.

Product overview

Solventum's Medical Membrane Materials portfolio comprises specialized capillary membranes designed for OEM integration into medical devices. The product line spans three primary therapeutic applications: blood oxygenation (including OXYPLUS, OXYPHAN, and X30 capillary membranes for cardiac surgery and respiratory therapies), hemodialysis and blood purification (including DIAPES, PUREMA, and SYNPHAN capillary membranes), and therapeutic apheresis (including SYNCLEAR, MicroPES, PLASMAPHAN, and FractioPES capillary membranes). These membranes serve as critical components in extracorporeal blood processing devices, enabling separation of blood components while maintaining biocompatibility and clinical efficacy. The company also offers customer-specific membrane manufacturing capabilities alongside standard product lines.
