Membrane Filters

MicroAnalytix offers membrane filters covering pore sizes from 0.015 to 12 µm.


Our broad offering of membrane materials (PTFE, regenerated cellulose, nylon, cellulose nitrate, polycarbonate, aluminum oxide, etc.) provides the user with an array of solvent compatibility options, porosities, and pore sizes according to individual specific needs. Some membrane materials are also available in sterile format.


Membrane filters are typically used in both liquid and air filtration. They offer accurately controlled pore size distribution with high strength and flexibility and are a suitable choice for a wide range of applications such as basic research, environmental testing, and pharmaceutical as well as food and beverage industries.
