Settle plate exposure under unidirectional airflow

Settle plates play an important part in the environmental monitoring programme and for the assessment of microbial settlement at key locations within cleanrooms, particularly when situated within unidirectional airflow devices. It is important that the exposure time of the settle plate is assessed to ensure that the proportion of weight loss (through the loss of moisture) does not result in a loss of growth-promoting properties. A second important concern is with avoiding cracks in the agar which might render reading sections of the exposed plate impossible. This paper outlines a case study to assess the exposure time through microbial growth promotion.

In relation to this key aspect of environmental monitoring, Tim Sandle has written a paper which has been published in the European Journal of Parenteral & Pharmaceutical Sciences.
