Dyed Polycarbonate Membrane Filters /
다이드폴리카보네이트멤브레인필터
These hydrophilic, 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.
Sterlitech offers two versions of the pigmented PCTE membrane filters to cover the broadest possible range of potential applications: Gray and Black.
The Gray variation has been pigmented using Irgalan Black dye and are ideal for applications where both fluorescence microscopy
and conventional optical microscopy may be performed on the same sample.
The Black variation has been pigmented using a proprietary dying process and are ideal for applications
requiring maximized contrast for optical microscopy studies of light colored particles or organisms.
