Viable air monitoring is crucial for pharmaceutical companies' contamination control strategy. According to GMP guidelines, compressed gases must also be monitored for microbial contamination. The MAS-100^® microbial air and compressed gas samplers meet requirements for cleanrooms, isolators, and RABS in pharmaceutical, food, beverage, and cosmetics manufacturing. They offer precision, ease of use, and complete validation, ensuring reliable air sampling. Using Anderson impaction, MAS-100^® samplers maintain a constant air flow rate, adjusting for variables to ensure accurate results.
