ABSTRACT:
A method for determining air borne bacteria which includes successive steps of passing a volume of air by a timed suction pump through a membrane filter at a membrane passing velocity of not more than 15 cm/sec and under a constant transmembrane pressure of not more than 100 mmHg to collect the air borne bacteria on the surface of the membrane filter. The membrane filter has a multiplicity of minute holes and is provided on a medium-absorbing pad housed in a holder. A medium is injected into the medium-absorbing pad housed in said holder. The bacteria thus collected are incubated and the number of the colonies developed on the surface of said membrane filter is measured.
