Millipore's Isopore™ membrane filter is a polycarbonate, track-etched screen filter recommended for all analyses in which the sample is viewed on the surface of the membrane. Isopore membrane offers distinct advantages for the analysis of airborne contaminants and other particles using optical or electron microscopy. The Isopore™ membrane is composed of polycarbonate film, which has a smooth, glass-like surface for clearer sample observation. The unique manufacturing process of the membrane ensures a precise pore diameter and a consistent pore size for accurate separation of samples by size. Isopore™ membranes do not stain resulting in low background interference. Clearing is not necessary for most transmitted light microscopy. Matched-weight filters are not usually required because of low, constant tar and ash weights. Isopore membranes are non-hygroscopic, which permits rapid drying and reduced sample analysis time. NOTE: Brown color may fade after autoclaving for sterility. Brown membranes are compatible with immersion oils, including Type B and Type F.
