Gelatine membrane filters in conjunction with the MD8 air samplers (gelatine filter method) are used for the collection of airborne microbes and viruses. These filters are completely water-soluble, therefore, microbes in one sample can be cultivated in different nutrient media or low and high bacteria counts can be measured.

• Pre-sterilised and ready to use
• Maintains viability of the collected microorganisms
• Solubility of the filter is a prerequisite for virus sampling
