Study Of Single Use Device Media Dehydration And Biological Recovery Efficiency

By Sara Todisco, Advisory Analyst

In this study, we review the performance of collecting contamination from continuous three-hour samplings using the BioCapt® Single-Use under unidirectional airflow, at 22 °C with 48% relative humidity. The BioCapt® Single-Use (BCSU) is an inertial impactor with elliptic cuts (slits) used to perform microbiological analysis and monitoring of air. It is made of transparent polystyrene, with visible culture media.

All four test results aligned with acceptance criteria, and visual inspection of the media post-sampling was satisfactory. With the backing of this study, BioCapt Single-Use can be used for three hour sampling with no change to its monitoring capabilities.
