Being biologically inert, they are suitable for a wide range of applications: sterile filtration, bio-assays, clear filtration, particle analysis in liquids and in air. Sterile, with grid, MCE These CME membrane filter have a high-contrast grid. The grid lines are spaced at 3.1 mm and do not affect colony growth. Sterile, packaged individually.

These filters enable high filtration quantities and thus reduce the need for filter changes. CA membrane filters are ideally suited for the filtration of proteins and enzymes, sterile filtration of cell culture media and other applications, i.e. wherever the preservation of the original protein composition and concentration is important.
