A breath of fresh air
The micro-organisms naturally present in normal cleanroom conditions are not evenly distributed in the air due to the fact that they are airborne by particulates.

It has been suggested that, to obtain accurate results of the natural microbial population, two paired air samplers or a "new generation" two-head air sampler should be used to calculate an average value. The DUO-SAS-360 air sampler by International PBI has been developed with the purpose of creating a single body with two contiguous aspirating heads for simultaneous sampling. The primary benefit of the instrument is its high flow rate of 180+180 litres/min, which is ideal for low contamination environments. Two different media can be used for simultaneous sampling, and up to 10 for "in operation" monitoring, according to USP recommendations.
