Gelatine disc filter, sterile, sealed in units of five each in a polyethylene bag

Gelatine filters in conjunction with the MD8 air samplers (gelatine filter method) are used for collection of airborne microbes and viruses. Gelatine filter disposables are individually packaged, pre-sterilised and ready-to-connect units, each consisting of a gelatine membrane filter and a holder. Gelatine membrane filters are still available as filter discs, suitable for the filter holder 17655 (80 mm diameter) supplied with the MD8 airscan® air samplers as well as in smaller diameters.

  • 'Absolute' retention rate (99.9995% for Bac. sub. niger, 99.94% for T3 phages)
  • The filter maintains the viability of collected microorganisms for a relevant and meaningful sampling time
  • Gelatine filters are completely water-soluble, therefore microbes in one sample can be cultivated in/on different nutrient media or low and high bacteria counts can be measured - the sample is not affected by inhibitors
  • The solubility of the gelatine filter is a prerequisite for virus sampling
