The Air Trace® Environmental Air Sampler is a state of the art slit-to-agar microbial air sampler. The sampler rotates a 150mm agar plate 360° while maintaining the agar plate at a fixed distance from a precision cut slit. This is a critical feature to ensure maximum validated recovery of impacted organisms on the agar surface. After incubating the plate, growth on the medium can be interpreted to exactly when the contamination occurred during sampling, enabling the operator to pinpoint a particular event during a process or procedure that may have raised the bio-burden to above acceptable limits. The user sets the rotation speed of the agar plate, as well as the percentage of the plate area exposed, thus ensuring the flexibility to monitor virtually any process for biocontamination.

The airflow through the instrument is automatically controlled at 1CFM (28.3 LPM). The built-in software automatically stores user ID and unique location information for each run, and an RS232 serial printer can be used to download data. A specially-designed version of the instrument, the Air Trace Compressed Gas, is available for the monitoring of compressed gases.
