What is a Portable Air Sampler?

A portable air sampler is a compact instrument used to collect airborne microorganisms such as bacteria and fungi from indoor air for laboratory analysis.It measures microbial contamination by drawing a controlled air volume onto agar media for colony-forming unit (CFU) counting.

What does a portable air sampler do? 

It collects airborne microorganisms from indoor environments and converts them into measurable CFU data after incubation. This helps evaluate microbial contamination in cleanrooms, hospitals, and laboratories.

How does a portable air sampler work?

1. Air is drawn using an internal calibrated pump

2. Air passes through a perforated sampling head

3. Microorganisms impact onto agar plates

4. Plates are incubated in laboratory conditions

5. Colonies are counted as CFU per cubic meter

What is portable air sampling used for?

Portable air sampling is used for monitoring microbial contamination in:

• Cleanrooms

• Pharmaceutical production areas

• Hospital operating rooms

• Microbiology laboratories

• Food production environments

Who uses portable air samplers?

• Pharmaceutical manufacturers

• Healthcare infection control teams

• Biotechnology laboratories

• Environmental monitoring agencies

• Quality control departments

Key Functional Capabilities

• Calibrated airflow control (typically 100 L/min)

• Adjustable sampling volume (100–3000 L)

• 90 mm Petri dish compatibility

• USB data export for documentation

• LCD display for sampling parameters

Technical Specifications

When should you use a portable air sampler?

Use this device when:

• Microbial contamination monitoring is required

• On-site sampling across multiple rooms is needed

• CFU-based air quality evaluation is required

• Portable environmental testing is required in controlled areas

What does CFU mean?

CFU (Colony Forming Unit) represents the number of viable microorganisms that grow on agar media after incubation. It is used to measure microbial air contamination levels.
