all Geotech filter membranes, they are Triton-free and non-reactive to pyrogens (<0.005ng/cm 2filter area). PTFE Membrane: Are highly porous and resistant to most acids, bases and chemically aggressive solvents. They are naturally hydrophobic making them difficult to use in common filtration of aqueous solutions. They must be pre-wetted with
Here, we've created a quick reference membrane filtration guide, listing membranes' compatible (and incompatible) solvents, helping you choose the most appropriate membrane for your sample. Polytetrafluoroethylene (PTFE) Membrane. Hydrophobic, highly inert, and durable, PTFE is a popular material with a wide operating temperature range and
MilliporeSigma™ Isopore™ Membrane Filters, 0.4 μm. Use for analyses of airborne contaminants and other particles using optical or electron microscopy. Isopore™ Polycarbonate Membrane Filters have a smooth, glass-like surface for clearer sample observation. Available in a variety of pore sizes/flow rates, diameters and colors.
They have a slightly higher extractable level at 3% (by wt.) and are composed of glycerin and wetting agent. As with all Geotech filter membranes, they are Triton-free and non-reactive to pyrogens (<0.005ng/cm 2 filter area). PTFE Membrane: Are highly porous and resistant to most acids, bases and chemically aggressive solvents. They are
