Black Polycarbonate (PCTE) Membrane Filters

For epifluorescence microscopy

  • Smooth flat surface- micro-organisms are retained in one plane on the surface
  • Do not stain
  • Essentially zero autofluorescence
  • Recommended for: epifluorescence microscopy; water testing; observation of bacteria (0.2-5 µm), yeasts and molds (0.6, 0.8 µm) and spores (5 µm); direct count of micro-organisms
  • pH range: 4-8

Standard polycarbonate membrane filters are treated by a proprietary irgalan black process to render them dark gray. This essentially eliminates the natural autofluorescence of the membrane. Except for a reduction of transparency, the membranes have the same characteristics as standard Poretics polycarbonate membrane filters. Ideally suited for fluorescence microscopy because:

  • The surface of the membrane is flat and smooth, assuring that no micro-organisms are captured within the filter structure as with ordinary tortuous pore filters.
  • They exhibit extremely low non-specific absorption
  • The elimination of autofluorescence assures high visibility against a non-distracting background
