Phytoplankton sampler is a commonly used detection instrument, which can accurately reflect the concentration of microorganisms in the clean room. Today I will mainly introduce the basic application knowledge of the plankton sampler, hoping to help users better apply the product. Brief introduction to plankton sampler a porous suction dust sampler. It is designed according to particle impact principle and isometric sampling theory. The sampling is direct, and the wind speed at the sampling port is basically consistent with the wind speed in the clean room, which can more accurately reflect the concentration of microorganisms in the clean room. During sampling, the dusty bacteria air passes through the micropores at high speed and is hit on the AGAR surface in the petri dish. In the process of culture, these living microorganisms undergo a dynamic rehydration process and grow at a high speed, so that the results can be obtained faster. The phytoplankton sampler is used for testing air microorganisms in clean rooms and sterile environment in GMP factory, dairy factory, hospital operating room, biological cleaning, fermentation industry and other clean rooms, as well as for sampling air microorganisms in relevant research and teaching departments. Operation method of planktonic bacteria sampler before use, wipe the surface of the sampler, the petri dish pedestal and the sampling head with medical degreased cotton soaked in 75% ethanol, and start the instrument to run idling for not less than 5 minutes to evaporate the residual disinfectant in the instrument. Parameters such as sampling amount were set according to the cleanliness level, and the samples were put into a petri dish containing culture medium, covered with a porous sampling head, placed on a horizontal surface 0.8m above the ground, and the instrument was started for direct sampling.
