FA 30

Filtration is the method of choice when high bacterial counts are expected. In Germany, filtration is stipulated for measurements at biological workplaces – e.g. compost works, waste sorting plants.

The filter adapter FA 30 is operated with the convenient MBASS30V3 or with separate pump.

Possible sampling media include commercially available gelatin filters in sterile disposable units (e.g. Sartorius SM 17528-080-ACD).
The use of other filter media is possible and depends for usage of the MBASS30 on the vacuum required.

The preparation and evaluation of the loaded filter is described in “Methods for determination of the mold spore concentration in the air at the workplace” in the BIA worksheet 9420. BIA is the Berufsgenossenschaftliche Institut für Arbeitsschutz (Trade Association for Industrial Safety).
