　　1、 Six level impact microbial sampler portable Anderson microbial samplerProduct Introduction

　　 Six level impact microbial sampler portable Anderson microbial samplerIt is a dual function multi-stage impact sampler that can be widely used for monitoring in environments such as hygiene and epidemic prevention, biological cleanliness, pharmaceuticals, and fermentation industry, as well as for sampling and studying air microorganisms in relevant research and teaching departments. It provides a basis for evaluating the hazards of microbial pollution in the air environment and its prevention and control measures.

　　The FA-1 six stage sieve impact air microbial sampler is not only capable of measuring the number of air microorganisms, but also has the ability to measure the size of these particles, which is one of the important indicators for determining the harm of air microorganisms. It is composed of six impactors combined into one, with each stage actually being a single-stage sampler. Using the principle of six repeated impacts, the vast majority of particles, especially those settling in the trachea and lungs, are basically impacted. Therefore, the particle size range it collects is naturally wider than that of single-stage impactors, which is unmatched by some single-stage impactors. Moreover, the circular nozzle of the sampler has higher sampling efficiency than the slit nozzle. The relative humidity increases step by step during sampling (from 39% to 88% in the sixth level), which is very beneficial for the survival of vulnerable pathogenic microorganisms, especially virus particles. Due to its unique characteristics, it has been widely and effectively used for monitoring airborne microorganisms, and has been widely used since its inception. Recommended by experts as an international standard sampler.

　　This sampler simulates the anatomical structure and aerodynamic physiological characteristics of the human respiratory tract. Based on the principle of inertial impact, microbial particles suspended in the air are collected at different levels on the surface of the sampling medium for cultivation and microbiological analysis.

　　The entire instrument consists of an impactor, a main unit (flow meter), a timer, and a tripod. The impactor is a 6-layer aluminum alloy disk with tiny holes. Place the agar plates on top of the discs, with sealing rings between each disc. The discs are firmly connected together using three spring hooks. Each disc has 400 small holes arranged in a circular pattern, gradually decreasing in size, with a standard sampling flow rate of 1 cubic foot (28.3 L/min). When the airflow containing microbial particles enters the sampling port in the upper layer of Z, due to the increasing height of the airflow layer by layer, microbial particles of different sizes collide with the corresponding agar surfaces according to their aerodynamic characteristics. The size range of particles captured at each level is determined by the airflow velocity of the holes in that level and the particle interception rate of the previous level. The particles captured by the upper respiratory tract in levels 1 and 2 are similar to those captured by humans, and the particles captured by the lower respiratory tract in levels 3 to 6 are similar to those captured by humans. This largely replicates the penetration and deposition of these particles in the respiratory tract.
