Membrane filters are surface filters used to remove particulate or collect microorganism for analysis from solutions, on and near the surface of the filter matrix by mechanical means. Our wide range 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 sterile.
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 suitable for a wide range of applications such as basic research, environmental testing and pharmaceutical, as well as food and beverage industries. We offer membrane filters by industry leaders such as Sartorius and Whatman.
In the second info box you will find more information about the application areas and the chemical resistance of the individual polymers.
