Six microbial air sampler JWL-6

Six microbial air sampler Model: JWL-6 Instrument: Product details works: JWL-6-type six microbial air sampler, percussive sieve six microbial air sampler in addition to the number of microorganisms capable of measuring the outside air its unique characteristics also measures the size of these particles, which is an important indicator of the determination of airborne microbial hazards. It is a combination of six impactor into one, each level is actually a single-stage sampler, use six times repeatedly hit principle, most of the particles, especially in the trachea and lung deposition of particles basically crash down, so it collected to a particle size range of natural than single-stage wide, which are some of the single-stage impactor unmatched, and round nozzle sampler sampling efficiency higher than cranny spout. Relative humidity stepwise increased (from 39% in the first grade rose to 88% of sixth grade) sampling, which is conducive to the fragile pathogenic microorganisms, especially viable virus particles. Because of its unique characteristics of these, it is widely and effectively used to monitor airborne microbes, since the advent of common ever. Experts recommended as an international standard sampler. Six microbial air sampler simulate human respiratory anatomy and physiology aerodynamic characteristics, sampling inertial impaction principle and suspended particles in the air hierarchically microorganisms collected on the sample surface of the medium, and for culture and microbiological analysis. Six microbial air sampler impact the entire instrument is made, a host (meter), timers, tripod composition. 6 striker is small perforations aluminum layer disc. Agar disk decentralization, between each disc sealing ring, linked by three springs the disc firmly linked together. There are 400 rows into the ring, layer by layer decreases on each disc standard sampling flow rate of 1 cubic foot (28.3L / min). When the stream of particles containing microorganisms into the uppermost layer of the sample port, due to the increased air flow layer by layer, microbial ions of different sizes aerodynamic characteristics are impinging on the respective agar surface. Capture at all levels of particle size range is from this level of airflow velocity and particle eyelet weir on the level and rate decision. First, the upper respiratory tract secondary human-like particles capture, 3-6 grade human-like particles in the lower respiratory tract capture, which replicate the penetration of these particles and calm parts of the respiratory tract to a considerable extent. Six microbial air sampler can offer the installation of good common nutrient agar plates. JWL-6-type six microbial air sampler technical parameters: Measuring range capture rate: ≥98% particle capture range of the first stage:> 7.0um Aperture: 1.18mm second stage: 4.7um ~ 7.0um aperture: 0.91mm third Grade: 3.3um ~ 4.7um aperture: 0.71mm fourth grade: 2.1um ~ 3.3um aperture: 0.53mm fifth grade: 1.1um ~ 2.1um aperture: 0.34mm sixth grade: 0.65um ~ 1.1um aperture: 0.25mm Sampling flow 28.3L / min ≤5% Adjustable noise ≤60db precision electronic timer range 1-24 hours, accuracy <1% Power supply 220V / AC power ≤45W Warranty 1 year warranty and lifetime service
