General description
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 – 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 for certain microorganisms.
Application
- Epifluorescence microscopy
- Environmental analysis
- Cell biologyEPA testing
- Fuel testing
- Bioassays
- Parasitology
- Air analysis
- Water microbiology
Features and Benefits
- 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
