Gelatine Membrane Filters, Diameter 25mm, Pack Size 50

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
