Membrane Filters Microsart™ e.motion
The membrane filters suitable for use in the Microsart™ e.motion are individually sterile-sealed,without protective paper on top of each filter, in a specially designed individual package on a band. For complete traceability, the membrane filter type, diameter, lot number and a unique serial number are printed on the package of each membrane filter unit. All Microsart membrane filters are "multi-fit" and can be used in all standard dispenser systems.The membrane filters have a diameter of 47 mm or 50 mm, and are white, green or grey with a high-contrast 3.1 mm grid.

Membrane filters Nitrocellulose PORAFIL®NC
PORAFIL® NC membranes are made from cellulose nitrate. They are easily wettable and suited for filtration of aqueous solutions. In dry atmosphere these membranes are thermally stable to 125 °C and can be autoclaved at 121 °C.
Membrane filters Polycarbonate PORAFIL®RC
Polycarbonate membranes are mainly used for the determination of AOX.
Membrane filters Polyester PORAFIL®PE
Polyester membranes are hydrophilic and particularly suited for fine filtration, dust analysis, aerosol analysis and ultra-purification of solvents.
Membrane filters Polytetrafluoroethylene PORAFIL®TE
Membranes of polytetrafluoroethylene (PTFE) are particularly suited for aggressive media, since they are chemically inert towards aqueous and organic solutions as well as towards concentrated acids and bases. These membranes are hydrophobic, thus the pressure for filtration of aqueous solutions has to be higher than the breakthrough pressure. PORAFIL® TE membranes can be used at temperatures up to 145 °C
Membrane filters PORAFIL®CM
Membranes of cellulose mixed esters are ideal for gravimetric analysis. They are particularly suited for aqueous solutions. The hydrophilic membrane is thermally stable to 125 °C and can be autoclaved at 121 °C. This membrane is often used for contamination tests.
