General description

These membranes are used to quantitatively evaluate microorganism counts. The liquid is filtered through a membrane and microorganisms collect on the membrane surface. The filter is incubated on a nutrient medium and the individual colonies can then be evaluated. The method is also suitable for large sample volumes and low microorganism counts.

  • Mixed cellulose ester membrane
  • Economical
  • Specifically for aqueous solutions
  • Hydrophilic
