The TRIO.BAS™ instruments utilize the impaction method of air sampling. The air, passing through an aspirating head, impacts onto an appropriate agar plate that collects bacteria or other organic substances possibly present in the sampled area. An attached HEPA filtration system filters the exhausted air. The actual filters are replaceable and sold separately.

All of our air samplers are lightweight, with an antibacterial techno-polymer shockproof body, have a long-lasting battery, and are IP65 protected from dust and water.

Per USP <797>, “Impaction is the preferred method of active air sampling. Use of settling plates for qualitative air sampling cannot be relied upon and shall not be used solely to determine the quality of air in the controlled environment.”
