Polycarbonate (PCTE) Membrane Filters, PVP-Free, Black, 0.2 Micron, 25mm, 100/pk
These hydrophobic, polycarbonate track-etch (PCTE) membrane filters have been pigmented using black dye to minimize membrane autofluorescence. The dyed PCTE membrane filters are ideal for use with fluorescence microscopy analyses that involve direct observation and enumeration of animal cells or microorganisms that have been labeled with fluorescent markers. They are also suitable for optical microscopy studies of light colored particles and microorganisms by providing a dark background for enhanced contrast.
