Microbial Air Sampler NMAS-201 is a controlled air monitoring instrument used to detect and quantify airborne microorganisms. It collects viable particles from air onto sterile culture media for laboratory incubation and microbial analysis.
It is widely used in contamination-sensitive environments where air quality validation is required.
Microbial Air Sampler NMAS-201 is used for:
Monitoring airborne microbial contamination
Cleanroom environmental validation
Pharmaceutical production quality control
Sterility assurance in healthcare environments
Food and beverage hygiene monitoring
Environmental microbial testing
Device works in a controlled sampling cycle:
Air is drawn into the system at a defined flow rate
Air passes through sterile collection media (agar/filter/impactor)
Microorganisms impact and stick onto the media surface
Media is incubated in laboratory conditions
Growth is measured as CFU (colony-forming units)
Results are used for contamination assessment
Microbial air sampling is essential for:
Preventing contamination in sterile environments
Maintaining product safety in pharma manufacturing
Ensuring regulatory compliance
Monitoring environmental microbial load
It supports:
ISO 14698 (Biocontamination control in controlled environments)
GMP (Good Manufacturing Practices for sterile production)
Adjustable airflow control (50–500 L/min)
Compatible with agar plates, filters, and impactors
Digital display for real-time monitoring
Portable design for lab and field use
High sampling accuracy and repeatability
Supports regulatory environmental monitoring
Pharmaceutical cleanrooms
Biotechnology laboratories
Hospital sterile zones
Food production facilities
Environmental monitoring labs
Use Microbial Air Sampler NMAS-201 when:
Airborne contamination must be measured precisely
Regulatory validation is required
Sterile production environments must be monitored
Microbial load tracking is part of QA/QC
Depending on requirements:
Compressed Air Sampler → for pressurized air systems
Particle Counter → for real-time particle monitoring
Ambient Air Sampler → for general environmental air quality
1.What does a microbial air sampler do?
It collects airborne microorganisms for laboratory incubation and CFU analysis.
2.How does Microbial Air Sampler NMAS-201 measure contamination?
It captures microbes on sterile media and measures growth after incubation.
3.Can it be used in cleanrooms?
Yes, it is designed for controlled cleanroom environments.
4.What microorganisms can it detect?
It detects bacteria, fungi, yeast, and spores.
5.What standards does it follow?
It follows ISO 14698 and GMP guidelines.
6.What is CFU?
CFU (Colony Forming Units) represent the number of viable microorganisms in a sample.
Microbial Air Sampler NMAS-201 is a precision instrument used to detect and quantify airborne microorganisms such as bacteria, fungi, yeast, and spores in controlled environments. It draws a measured volume of air and captures viable microbes on sterile agar plates or filters for incubation and colony-forming unit (CFU) analysis. Widely used in pharmaceutical cleanrooms, biotechnology laboratories, hospitals, and food processing facilities, NMAS-201 supports effective contamination control and compliance with ISO 14698 and GMP standards.
