CN membrane filters

Cellulose nitrate is a standard material for membrane filters and offers a wide range of pore sizes from 8 µm to 0.45 µm. The larger pore sizes (8 µm, 5 µm, 3 µm) find use for cell retention, the 0.45 µm pore size for particle collection. The high non-specific adsorption of the cellulose nitrate membrane is very advantageous for diagnostic kits.
