MCE Black Membranes

  • Suitable for microbiological analysis of light-coloured
    or transparent bacteria
  • Black membranes provide excellent contrast between cell colour / residue and the filter, without having to counter-stain the membrane
  • Most used for manual counting procedures, analysis of yeast, mould and Legionella sp.
