Nuclepore Membrane Circles, Black 47mm 0.2µm, 100/pk

Details

Cytiva's Nuclepore black membrane filters are polycarbonate track-etched (PCTE) membranes with high particle visibility for standard plate count and epifluorescence microscopy applications.

Smooth, gridded PCTE membrane surface efficiently supports microorganism enumeration in a standard plate count
Irgalan black membranes for reduced background fluorescence in support of epifluorescence microscopy
Extremely low nonspecific absorption

Explore the full range of Whatman NucleporeÂ polycarbonate membrane filtersÂ from Cytiva's business for hydrophilic, hydrophobic, black, and gold-coated membranes

Black membranes for rapid standard plate count results

Cytiva's Nuclepore membrane filters are compatible with the direct epifluorescent microscopy filter technique (DEFT), which allows microorganisms to be counted directly on a filter. DEFT can be conducted in under half an hour, sidestepping the standard > 24 hour process of incubating a microbial sample.

Cytiva's irgalan black membranes greatly reduce background fluorescence, improving visibility and helping to distinguish microorganisms from other particulates.

Microscopic membrane filters

Cytiva's microscopic membrane filters are made by track-etching â€“ the polycarbonate is bombarded with radiation and chemically treated to create sharp, uniform filter pores. The PCTE membrane is designed to trap microbes efficiently, and can be more effective than other filter media forÂ certain microorganisms.

Looking for a filter paper, membrane filter, or syringe filter Let Cytiva help youÂ find the optimal filterÂ for your needs to ensure reliable analysis.
