Choose the time, temperature and type of culture medium according to your
microbiological application, for instance, Standard, Caso or Plate Count Agar are suitable
for determining the colony count; Sabouraud, Malt Extract or Wort Agar for detecting
yeasts and molds; and Blood Agar for detecting pathogenic microbes causing hemolysis.
You can obtain the number of colony forming units per cubic meter of air by relating the
colony count obtained to the volume of air sampled (cfu/m
3
).
We recommend that you plate the gelatin filter on a suitable agar immediately after
sampling is completed, as this avoids possible inactivation of very sensitive bacteria due
to drying-out effects.
If the filter is transported to the laboratory, then the filter unit should be protected
from contamination by covering it with a sterile petri dish lid or wrapping it in sterile
aluminium foil, until its removal under sterile conditions (sterile bench, laminar-flow
glove box or isolator).
