Gelatine Membrane Filters
Air Monitoring | Gelatine Membranes Microbiological
Analysis
Gelatine filters in conjunction with the MD8
air samplers (gelatine filter method) are used
for collecting of airborne microbes and viruses.
Gelatine filter disposables are individually
packed, presterilized 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.
Gelatine filters in conjunction with the MD8
air samplers offer the following features and
benefits:
– "Absolute” retention rate (99.9995%
for Bac. sub. niger spores, 99.94% for
T3 phages).
– The filter maintains the viability of
collected microorganisms for a relevant
and meaningful sampling time.
– Gelatine filters are completely watersoluble.
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.
