详细内容
1 Product Overview
The GR-1353 Air Microbial Sampler (hereinafter referred to as the sampler) is a sampling instrument specially developed by our company for collecting microorganisms in the air. It is based on the principle of Anderson＇s impact method, extracting air at a certain flow rate, causing the microbial particles in the airflow to accelerate ａnd impact on the surface of the petri dish containing nutrient agar medium, forming colonies visible to the naked eye after cultivation, counting the colonies ａnd calculating the concentration of living individuals in the air according to the The colonies are counted ａnd the concentration of viable individuals in the air is calculated from the volume sampled.
