Introduction: The HKM-MAS-6L six-stage perforated air microbial sampler (plankton microbial sampler) can be widely used in disease prevention and control, environmental protection, pharmacy, fermentation industry, food industry, biological cleanliness and other environments on the number of air microorganisms and The particle size distribution monitoring of the particles attached to microorganisms, in addition, scientific research and teaching departments can use the equipment to sample and study air microorganisms, providing a scientific basis for evaluating the hazards of environmental air microbial pollution and real treatment measures. working principle: The complete set of equipment consists of a six-stage sampling impactor, a sampling control host, and a special tripod for the six-stage sampling impactor. The six-stage sampling impactor is composed of six hard-oxidized aluminum porous impact sampling disks. The porous impact sampling disk can be placed on a sterile plate with sampling media. All porous impact sampling disks are composed of Three spring hooks tightly connect the porous percussion sampling discs together. There are 400 precision micropores with the same pore diameter arranged circularly on the same-level porous impact sampling disk, and the pore diameters of the impact sampling disks of different levels are different. When the air containing microbial particles enters the sampling port, the gas sampling flow rate of the sampling host is constant, and when the gas passes through the sieve holes of the different apertures of the sampling disc at each stage, the microbial particles of different sizes collide at different speeds according to the aerodynamic characteristics. On the surface of the corresponding sampling medium. The first-second level is similar to the particles captured in the upper respiratory tract of the human body, and the third-sixth level is similar to the particles captured in the lower respiratory tract, which simulates the penetration and deposition of these particles in the respiratory tract to a considerable extent. Features: 1) Comply with ISO/DIS 14698-1 sampling standard; 2) Reliable air sampling design, with up to 400 micro-holes in each sampling head, so that the collected microorganisms can be evenly distributed on the surface of the culture medium, reducing the overlap of dust and bacteria, and improving the accuracy; 3) With real-time flow display, the sampling flow rate can be easily adjusted to ensure the accuracy of the sampling volume. 4) High-definition LCD touch screen, rich display of inner kiln, user-friendly menu settings, simple and intuitive operations; 5) USB communication connection shortcut, simple and quick access to PC, through data management software, realize efficient traceability management, and export sampling report (some models) through PC. 6) The start-up time and sampling volume of the sampler can be directly set through the operation panel, and the control of the sampler can also be achieved through the Bluetooth function on the mobile phone; 7) The calibration operation is simple, and the flow can be calibrated directly through the flow adjustment knob. The calibration is simple and easy; 8) Fully automatic loop sampling function, which can achieve up to 99 consecutive sampling within 100 hours; 9) Easily realize the traceability of equipment operation, large-capacity equipment operation storage, can automatically record 4000 sets of sampling data (including the set sampling location number, sampling group number, sampling amount, sampling time, etc.), which can be entered by time period Query the sampling record data of the corresponding time period at any time 10) High-efficiency sampling pump, which can realize long-term continuous sampling by the sampler 11) The housing of the whole machine is made of high-quality aviation aluminum, and the sampling head can be steam sterilized or wiped and sterilized with 75% alcohol 12) Use standard universal petri dishes φ70mm or 90*13-15mm, no need to use expensive special consumables 13) Built-in imperial unit and metric unit sampling settings 14) Built-in processor temperature measurement, monitoring equipment operating status at any time 15) Built-in Chinese and English operation interface Technical Parameters: Number of micro-holes in each layer of sampling head: 400 Sampling flow: 28.3 L/min Microbial capture rate: ≥98% Sampling volume: Metric unit: 10-6000 (L) arbitrarily set (take 10L as the unit) Applicable petri dishes: φ70 or 90×13-15mm standard petri dishes Display: touch, high resolution 800×480 Bluetooth remote control: the sampler can be turned on by Bluetooth control Program loop sampling: can achieve up to 99 consecutive sampling within 100 hours Sampling parameter setting: 99 groups of 30 points Recording function: 400 sets of sampling data records Power supply: AC110V-240V 50/60HZ to DC24V
