This technique can be used for most membrane filters with a single refractive index. The refractive index for Durapore membrane is 1.42 and for MF membrane its 1.50. Please note that this does not work for polycarbonate membranes because these membranes have more than one refractive index (1.62 and 1.58).

Product Number Product Description SDS PM2547050 PTFE membrane, The PTFE Membrane for PM2.5 Particle Monitoring is a filter disc used in conjunction with PM2.5 Environmental Monitoring equipment., hydrophobic, pore size 2.0 μm, white filter, plain filter
Merck ptfe 0.2 micron filter for chemicals Whatman® membrane filters PTFE pore size 0.2 μm, Usual pore sizes are 0.2 μm and 0.5 μm. Sterile venting of vacuum manifolds, fermentation vessels, and sterile filtrate tanks and containers utilize PTFE 0.2 μm
PTFE membrane filters have an excellent chemical compatibility (pH 1 to 14), so that they are also used for the filtration of solvents and acids, to which other filter types are not resistant. Moreover they can be used to filter aqueous solutions as well, but because of their hydrophobic characteristics, they must be pre-wetted with ethanol or methanol before the filtration of
