Isopore^TM Membrane Filter

32031602

NB.24

The Isopore^™ membrane 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 many 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. Matched-weight filters are not usually required because of low, constant tar and ash weights.

Isopore^™ membrane filter has been used:

• in air monitoring
• in epifluorescent microscopy,
• in chemotaxis assays
• for culturing organotypic brain slices
• organotypic vibrosections
• as a working electrode for the synthesis of Helical nanomotors.

Possible reduction in flow rates may occur after autoclaving.
