1. Instrument Description
FA‑1H Microbial Air Sampler (hereinafter referred to as the sampler) is designed and manufactured based on the particle impaction principle and the classic Stokes equation, complying with international standards for microbial air samplers. The sampler is applicable to various air microbial sampling and testing tasks. It can directly collect airborne microorganisms onto the surface of semi‑solid nutrient agar. After incubation, counting and calculation, the microbial colony count per cubic meter of air can be determined. This instrument features high collection efficiency, short sampling duration and a full detection range.
2. Scope of Application
It is widely used for airborne microorganism monitoring in health and epidemic prevention, biological cleanrooms, pharmaceutical industry, as well as sampling research by relevant research and teaching institutions. It provides data support for assessing the hazards of airborne microbial contamination and corresponding control measures. It meets national standard requirements and is suitable for CDC, health supervision authorities, entry-exit inspection and quarantine bureaus, third-party testing laboratories, research institutes and universities.
3. Applicable Standards
- JJF 1826-2020 Calibration Specification for Microbial Air Samplers
- GB/T 18204.3-2025 Examination Methods for Public Places — Part 3: Air Microbial Indicators
