Particle Counters
Viable Particle Counters for Microbial Assessment
Viable particle monitoring remains essential for comprehensive cleanroom environmental monitoring programs. Our active air sampling equipment represents the gold standard in microbial detection systems.
How Viable Particle Counting Works
Our viable particle counter systems draw ambient air through a calibrated inlet and direct the airstream onto culture media plates. This methodology ensures:
- Accurate quantification of airborne microorganisms
- Identification of specific contaminant species after incubation
- Compliance with USP <797> and EU GMP Annex 1 requirements
- Documentation of microbial control effectivenes
Strategic Monitoring Applications
When implementing a viable particle count program, strategic placement of samplers provides critical data about:
- Primary Engineering Control (PEC) Conditions – Verifying aseptic conditions within critical zones
- Room Environment Assessment – Detecting microbial contaminants in surrounding workspaces
- Personnel Impact Analysis – Measuring human contribution to bioburden
- Process Validation – Confirming effectiveness of cleaning and disinfection protocols
Surface and Personnel Monitoring
Beyond airborne viable particle monitoring, our comprehensive approach includes:
Surface Sampling Equipment – Critical for evaluating contamination on:
- Laminar airflow workbenches
- Equipment surfaces
- Hard-to-reach areas including filling needles and tubing
- Floor areas and vertical surfaces
Fingertip Testing Kits – Essential for validating:
- Effectiveness of hand hygiene protocols
- Proper gloving techniques
- Personnel aseptic competenc
Non-Viable Particle Counters for Precision Measurement
Non-viable particle counting forms the foundation of cleanroom classification and continuous monitoring. Our instruments provide real-time data on particulate levels across all critical size ranges.
