Microbial Air Samplers – Laboratory & Cleanroom Monitoring

What is a Microbial Air Sampler?

A microbial air sampler is an instrument used to collect and measure airborne microorganisms in controlled environments.

It helps ensure air quality, contamination control, and compliance with ISO 14698 and GMP standards.

What Do Microbial Air Samplers Measure?

These devices measure:

• Bacteria

• Fungi and yeast

• Airborne spores

Results indicate microbial contamination levels in the air.

How Do Microbial Air Samplers Work? 

1. Air is drawn into the sampler

2. A defined volume of air is measured

3. Microorganisms are captured on agar plates or filters

4. Samples are incubated or analyzed

5. Microbial colonies are counted and evaluated

Controlled airflow ensures accurate microbial sampling.
