Trio Bas Duo
The TRIO.BAS™ Duo (by ORUM International) is a portable, dual-head microbial active air sampler (impaction method) designed for environmental monitoring in cleanrooms, pharmaceutical aseptic filling suites, biotech facilities, hospitals, and other controlled environments. It uses two stainless steel aspirating heads to collect airborne viable particles onto agar plates (Petri 90 mm or Contact/Rodac 55/65 mm). The dual-head design allows simultaneous sampling with two different media, sequential sampling, or faster total volume collection, making it ideal for high-volume monitoring and staff rotation. This is a robust, user-friendly tool for regulatory-compliant viable air monitoring.
Manufactured in 2022.
