Introduction: FSC-A6 six-stage impact planktonic bacteria sampler is composed of impactor and host. The impactor is a 6-layer aluminum alloy disc with tiny perforations. An agar plate is placed under the disc, and there is a sealing rubber ring between each disc, and the discs are firmly connected together by three spring hooks. Each disc has 400 holes of accurate size in a circular arrangement, decreasing layer by layer, with a standard sampling flow rate of 1 cubic foot per minute. When the airflow containing microbial particles enters the upper sampling port, the microbial particles of different sizes impinge on the corresponding agar surface according to the aerodynamic characteristics due to the increase of the airflow velocity layer by layer. The size range of particles trapped at each stage is determined by the airflow velocity of the perforations of this stage and the particle interception rate of the previous stage. The first and second stages of the FSC-A6 six-stage impact planktonic sampler are similar to the particles captured by the upper respiratory tract of humans, and the third to sixth stages are similar to the particles captured by the lower respiratory tract of humans. Penetration and deposition sites of the respiratory tract. Technical parameter: Measuring range: Capture rate: ≥98% Captured particle range: first stage: >7.0μm aperture 1.18mm Second stage: 4.7μm – 7.0μm aperture 0.91mm Third stage: 3.3μm – 4.7μm aperture 0.71mm Fourth stage: 2.1μm – 3.3μm aperture 0.53mm Fifth stage: 1.1μm – 2.1μm aperture 0.34mm The sixth grade: 0.65μm – 1.1μm aperture 0.25mm Sampling volume: 28.3L/min error <5% Sampling period: 1-99 minutes can be set arbitrarily Noise: ≤50db Working power: 220V/AC Power: ≤ 45W Host size: 210×250×130(mm) Weight: 4.7Kg Impactor size: 110×110×850 (mm) Weight: 1.1Kg
