Sartorius 12602--47----ALN 1.9" Gelatin Membrane Filter, Pack of 100

Gelatine filters in conjunction with the MD8 air samplers (gelatine filter method) are used for collection of airborne microbes and viruses - individually, sterile packaged membranes guarantee reliable and accurate results.

Features

• "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
• Water soluble, pore size 3µm, thickness approx. 250µm
• Bac. subtilis niger spores 99.9995% at 0.25m/s inlet velocity
• Coli-Phages: phage T1, 99.9% at 0.3m/s inlet velocity and 50% rel. air humidity
• Phage T3, 99.94% at 0.3 m/s inlet velocity and 80% rel. air humidity
