Sigma-Aldrich Swinnex®Filter Holder, polypropylene

Swinnex™ Filter Holders allow you to build your own syringe filters by choosing the membrane material and pore size that best fit your application. These reusable holders are designed to accommodate a variety of membrane diameters and are ideal for ultracleaning or sterilizing small to moderate volumes of liquid using a syringe or by in-line setup.

The holders are autoclavable with the membrane in place, making them well-suited for sterile filtration workflows in laboratory and research environments. Constructed for convenience and flexibility, Swinnex holders are available in 13 mm, 25 mm, and 47 mm formats to suit a range of process volumes.
