Abstract: The GMP Annex 1 2023 requests that microbial environmental monitoring by active microbial air samplers is actuated by continuous air monitoring. A prolonged sampling produces a loss of moisture in the agar of the Petri dish and therefore it is necessary that during the “continuous time†the dryness of the nutrient media is under control to guarantee a regular growing of the CFU. The purpose of this paper is to evaluate if the agar (which volume was reduced with a treatment under sterile laminar flow before aspiration) has still the correct nutrient characteristics during the incubation of the Petri dishes. The tested instrument was a AIR. BIO ONE air sampler with an aspiration rate of 25 liters / minute. The results of the study are summarized in (Tables 1 & 2).
