摘要:Plankton sampler can be equipped with a special ******** bracket, the sampling height can be adjusted. Compressed gas sampling nozzle can be selected, and 8bar pressure holding sampling can be carried out when the pressure is controllable. Instrument air suction device will be through a porous sample head suction, hit the Ф 90 mm petri dishes, the microbe in air was "captured" on AGAR medium. It is an efficient multi-hole suction sampler based on the Anderson impact principle with an impact vel.
Plankton sampler can be equipped with a special ******** bracket, the sampling height can be adjusted. Compressed gas sampling nozzle can be selected, and 8bar pressure holding sampling can be carried out when the pressure is controllable. Instrument air suction device will be through a porous sample head suction, hit the Ф 90 mm petri dishes, the microbe in air was "captured" on AGAR medium. It is an efficient multi-hole suction sampler based on the Anderson impact principle with an impact velocity of 10.8m/s, equivalent to the fifth Anderson impact. Standard impact sieving working mode, equivalent to Anderson impact level of the fifth tip air flow sensor, constant current sampling, flow control precision is high. Power shortage or flow error more than 2.5% automatic shutdown. Automatic measurement of ambient temperature, atmospheric pressure, flow with temperature, atmospheric pressure change automatically maintain constant current. Dot matrix LCD, Chinese menu operation, real-time clock display. Real-time conversion of environmental parameters without recalibrating extremely high atmospheric pressure at any temperature altitude. It can be widely used in the pharmaceutical industry, food industry, beverage tap water, drug inspection, health and epidemic prevention, hospitals, public places and other related industries and departments.



Some important points to note before packing or transporting the plankton sampler:



1, the machine surface can also be wiped with alcohol or water.



2. Be careful not to splash water on the circuit or electronic connection.



3, surface dirt with a soft cloth dipped in about 70% alcohol or water or other commonly used disinfectant wipe.



4. Perforated cover and dustproof cover can be sterilized under high temperature and high pressure (15 min /121℃) 6.5.3 pay attention that the hole of the perforated cover is not blocked.



5. Sampling result correction: first, microbial colony count needs to be corrected in the Feller statistical correction table (see attachment), and then converted to the number of contaminated particles per cubic meter. The principle of the calibration table is that as the sampling volume or number of samples increases, the probability of two or more microorganisms entering the petri dish through the same hole increases.



6. Need to check regularly.
