The ability of SKC Gelatin Filters to collect extremely low bacte-
ria counts at high flow rates makes it one of the most efficient
media to use for sampling bioaerosols.

Gelatin Filters For the Collection of Bioaerosols
Performance Profile:
Material: Water-soluble gelatin
Pore size: While having a nominal pore size
of 3.0 碌m, a higher capture effi-
ciency of sub-micron particles can
be expected due to the separations
that occur on the surface and
within the filter. It is through in-
ertial impaction and diffusional
interception that these filters can
remove particles much smaller
than 3.0 碌m.
Diameter: 25 mm or 37 mm
