Microbial plankton sampler is a commonly used sampler product, widely used in the pharmaceutical industry, food industry, beverage tap water, drug testing, health and epidemic prevention, hospitals, public places and other related industries and departments. Today, Xiaobian will introduce the basic application knowledge of the microbial planktonic sampler, hope to help everyone.
Microbial plankton sampler use:
The microbial planktonic sampler is used for air microbial detection in clean rooms and aseptic environments in pharmaceutical GMP plants, dairy plants, hospital operating rooms, bio-cleaning, fermentation industries, and related research and teaching departments for air microbial sampling studies.
Microbial plankton sampler principle:
The microbial floating bacteria sampler is based on the Anderson impact principle (impact method), and collects the isokinetic sampling theory design that the air velocity is basically the same as the clean indoor wind speed. Direct sampling, the airborne microbes are impacted on the agar surface in the culture dish through the micropores at high speed. Particles larger than 1 micron are guaranteed to be captured and collected.
Microbial plankton sampler method:
Before use, wipe the surface of the sampler, the holder of the culture vessel and the sampling head with a medical degreased cotton soaked with 75% ethanol, and start the instrument to run idle for no less than 5 minutes to evaporate the residual disinfectant in the instrument. According to the cleanliness level, set the sampling amount and other parameters, put it into the culture dish containing the medium, cover the porous sampling head, place the horizontal surface at a height of 0.8m from the ground, and start the instrument to directly sample.
Microbial plankton sampler features:
1) Constant velocity sampling design: The collecting port wind speed is basically the same as the clean room wind speed, which can more accurately reflect the microbial concentration in the clean room. Optimized the impact velocity to control the false positive results, thus ensuring microbial collection efficiency;
2) Friendly and intuitive operation interface: full Chinese display menu, large screen LCD display sampling amount (0.01-6.0m3), set sampling location code, sampling delay time, screen backlight time, language (Chinese and English), date, light touch Keyboard and easy to understand interface;
3) Efficient open system: no need to buy special test paper plates or filter paper;
4) The sampling direction is adjustable: the sampling head can be adjusted from horizontal to upright 90 degrees to meet multi-angle sampling, and the tripod can also be installed in different environments (the tripod support module is optional);
5) Porous sampling head: up to 589 holes, which reduces the possibility of dust and dust overlap during effective sampling and reduces microbial counting errors. Through Feller calibration, the more the number of openings, the closer the number of colonies on the plate is to the bacteria contained in the actual air;
6) Strong traceability: Each sample is automatically generated and stored in the sampler after each sample run. It can store up to 2000 pages of data, and can quickly query the sample record: time, location, sample size and other parameters. The HKM-IIA sampler can also be connected to a computer with a data cable, allowing data to be downloaded to a computer for reporting and sampling analysis via the HKM sampler software;
7) Long use time: It can be used continuously for up to 15 hours, large capacity, rechargeable polymer lithium battery, no capacity memory effect, safe and durable;
8) 95% sampling efficiency: According to ISO 14698-1 Appendix B and Appendix C, establish a physical sampling efficiency experiment, the physical sampling efficiency of particles from 0.8 to 19.0 microns in diameter can reach more than 95%.
