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.

• Monitor separate cleanrooms with a single external command unit and two satellites connected to 5 meter long cables
• Use separate culture media at the same time to determine bacterial and fungal counts
• Ideal for use with Isolators or RABS (Restricted Access Barrier Systems)
• 100 or 200 liter per minute formats, contact plate or Petri plate formats available
• Charges via cable; sample up to 70000 liters on a single battery charge

Per USP 797, Volumetric active air sampling of all classified areas using an impaction device must be conducted in each classified area [e.g., ISO Class 5 PEC and ISO Class 7 and 8 room(s)] during dynamic operating conditions at least every 6 months.
