Cytiva's Whatman brand Cyclopore black membrane filter is a polycarbonate track etch membrane (PCTE membrane) that provides a contrast background for epifluorescence and other microscopy applications.
High visibility black membrane filter for epifluorescence
Because of their low background fluorescence, microfiltration membranes with a dark surface can improve test sensitivity in epifluorescence. Cyclopore black membrane filters offer a consistent contrasting background for excellent visibility during particle analysis.
