Membrane Filters Microsart™ e.motion | Pore size µm: 0.45, Colour: green/dark green, Ø mm: 50
Membrane Filters Microsart™ e.motion | Pore size µm: 0.45, Colour: green/dark green, Ø mm: 50
Brand: Sartorius Lab InstrumentsAvailable in 16 variantsThe 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. Specially developed pore structures of the 0.45 ìm high Flow membrane filters permit faster filtration based on their high flow rates and throughputs.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 Polytetrafluoroethylene PORAFIL®TE | Ø mm: 220, Pore size µm: 3.00
Membrane filters Polytetrafluoroethylene PORAFIL®TE | Ø mm: 220, Pore size µm: 3.00
Brand: Macherey-Nagel GmbH & Co. KGAvailable in 31 variantsMembranes 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
