Pre-cut Membranes

We offer a wide variety of filter materials including pre-filter membranes, as well as hydrophobic and hydrophilic materials, in a variety of formats to suit your product or application needs

This guide provides an introduction our membranes which are typically used in venting and filtration applications.

Also, included in this guide is a performance characteristic table which details the most pertinent product attributes and outlines the performance (e.g. flow rate, biocompatibility and average bubble point) of each of our microfiltration membranes.

We offer a wide variety of precut membranes in Nylon, Cellulose Acetate, PVDF, PES, Nitrocellose and PTFE. 

  • Sizes 13mm to 142mm
