Bacterial Air Sampler LMBAS-A100 – Portable Microbial Air Monitoring Instrument

What is a Bacterial Air Sampler?

A bacterial air sampler is a laboratory instrument used to collect airborne bacteria and other microorganisms on agar media for CFU (colony-forming unit) analysis. A bacterial air sampler collects airborne microorganisms by drawing a controlled air volume and impacting them onto agar plates for incubation and CFU counting.

What is LMBAS-A100 used for?

It is used for measuring viable airborne microbial contamination in controlled and non-controlled indoor environments.

Main applications:

• Pharmaceutical cleanroom monitoring

• Hospital sterile environment testing

• Microbiology laboratory air analysis

• Biotechnology facility monitoring

• Food production hygiene control

• Environmental microbial studies

Why is bacterial air sampling important?

Bacterial air sampling is used to detect living microorganisms in air that cannot be measured using particle counters.

It supports:

• Contamination control programs

• Sterile environment validation

• Regulatory compliance reporting

• Environmental risk assessment

How does LMBAS-A100 work? (Step-by-Step)

Step 1: Air Intake

A fixed volume of air is drawn into the system at 100 L/min.

Step 2: Airflow Control

Air passes through a calibrated perforated sampling head.

Step 3: Microbial Impact

Airborne bacteria impact onto agar media surface.

Step 4: Incubation

Petri dishes are incubated under controlled laboratory conditions.

Step 5: Colony Formation

Viable microorganisms grow into visible colonies.

Step 6: CFU Calculation

Results are expressed as CFU/m³ (colony-forming units per cubic meter).

What is CFU in microbial air sampling?

CFU (Colony Forming Unit) represents viable microorganisms that grow into colonies after incubation of air samples collected on agar media.

What microorganisms can it detect?

• Bacteria

• Fungi

• Mold spores

• Viable airborne biological particles

Where is LMBAS-A100 used?

• Pharmaceutical cleanrooms

Frequently Asked Questions 

Q1. What does a bacterial air sampler do?

      It collects airborne bacteria onto agar plates for incubation and CFU analysis.

Q2. How does bacterial air sampling work?

       Air is drawn through a perforated head and microorganisms are impacted onto culture media.

Q3. What is CFU?

      CFU represents viable microorganisms that form colonies after incubation.

Q4. Where is bacterial air sampling used?

      It is used in cleanrooms, hospitals, laboratories, and pharmaceutical facilities.

Q5. What is the difference between a particle counter and bacterial air sampler?

       A bacterial air sampler detects living microorganisms, while a particle counter measures non-living particles.
