Gelatin Filter

Gelatin filters are used together with MD8 air samplers, using the gelatin filter method, for the collection of airborne microbes and viruses. Disposable gelatin filter materials are individually packaged, pre-sterilized, ready-to-connect units, each consisting of a gelatin membrane filter and a holder.

Gelatin membrane filters are available for filter holder 17655, with an 80 mm diameter, supplied with MD8 Airscan® air samplers, and are also still available as filter discs in smaller diameters.

• “Absolute” retention rate: 99.9995% for Bac. sub. niger and 99.94% for T3 phages
• The filter maintains the viability of the collected microorganisms for a relevant and meaningful sampling time
• Gelatin filters are completely water-soluble; therefore, microbes in a sample can be cultivated in or on different nutrient media, or low and high bacterial counts can be measured without the sample being affected by inhibitors
• The solubility of the gelatin filter is a prerequisite for virus sampling
