General description
Need a custom membrane filter? Click here to request a custom membrane filter or unique and large package sizes that may not be available via our website.
The Isopore™ membrane comprises polycarbonate film, with a smooth, glass-like surface that aids in clearer sample observation. This track-etched screen filter is recommended for sample analysis on the membrane surface. Isopore™ membranes are useful in airborne contaminants analysis using electron microscopy.
