This technical report presents the validation of an external gelatin filter used with the MicronView Remote BAMS (BioAerosol Monitoring System). The objective is to demonstrate reliable culture-based recovery (CFU/m³) when the Remote BAMS is operated with an external gelatin filter under conditions representative of pharmaceutical isolators and cleanrooms. The Remote BAMS integrates biofluorescent particle counting (BFPC) with conventional particle monitoring while the external gelatin filter enables downstream culture and organism identification from the same airflow path.
