摘要:Planktonic bacteria sampler is a porous inhalation dust bacteria sampler. It is designed according to the principle of particle impact and the theory of isokinetic sampling. The sampling is direct, and the wind speed at the sampling port is basically the same as the wind speed in the clean room, which can more accurately reflect the microbial concentration in the clean room.

Planktonic bacteria sampler is a porous inhalation dust bacteria sampler. It is designed according to the principle of particle impact and the theory of isokinetic sampling. The sampling is direct, and the wind speed at the sampling port is basically the same as the wind speed in the clean room, which can more accurately reflect the microbial concentration in the clean room. When sampling, the air with dust bacteria passes through the micropores at high speed and is hit on the surface of the agar in the petri dish; these living microorganisms undergo dynamic rehydration during the culture process and grow at a high speed, so that the results can be obtained faster.

In the atmospheric environment, to detect the planktonic bacteria in the air, we need to use the air planktonic bacteria sampler. What if it is to detect planktonic bacteria and microorganisms in compressed air? In fact, this air planktonic bacteria sampler is also used, but an additional compressed air collector is needed to connect between the compressed air and the planktonic bacteria sampler. In this way, even the planktonic bacteria and microorganisms in the compressed air can be detected.

Product structure of planktonic bacteria sampler


Operating rules description:
  1. Purpose
Establish a standard operating procedure for the plankton sampler to ensure the correct use and reasonable maintenance of the instrument.
  2. area
is suitable for planktonic bacteria sampler.
3. Responsibilities
QA personnel comply and execute.
4. Content
4.1 Preparation basis
Planktonic bacteria sampler instruction manual.
4.2 Preparations
4.2.1 Pour the prepared culture medium into a sterilized petri dish, pre-incubate at 30~35°C for 48 hours, and use it after confirming the sterility.
4.2.2 After irradiating the instrument with ultraviolet light or wiping it with 75% alcohol, it shall be introduced into the clean room in a sterile state.
4.3 Operation method
4.3.1 Place the sampler on the work surface and use the sampling port to sample directly. If the measurement position is high, a sampling tube can be used to extend the tube to the space to be sampled.
4.3.2 Turn on the power supply, and press the set key according to the selected period. The setting button can be set for 1~10, 20, 30~90 minutes in 18 steps, that is, every time you press the setting button, 10 minutes will be added.
4.3.3 Place the petri dish containing the culture medium on the turntable, put on the outer cover, and press the pressing block to seal the outer cover and the base.
4.3.4 Adjust the dial and rotate the adjustment knob to keep the slit and the culture medium at a distance of 2mm.
4.3.5 Press the start button, the machine will wait for 15 seconds, the pump will start to pump air, the turntable will start to rotate 360°, adjust the flow knob to make the upper end of the flowmeter float level with the 50L scale line. After sampling is completed, unscrew the cover, quickly put the lid on the plate and take it out, and put in a new plate according to the above method for the second sampling (if a sampling tube is used, replace the pre-sterilized second sampling tube) .
4.3.6 Place the removed plate in an incubator at 30~35°C, and count it after 2 days.
4.3.7 After use, fill in the "Inspection Equipment Use Record".
4.4 Matters needing attention
A. In order to achieve the best test results, preheat the instrument for 30 minutes before using it.

B. At the beginning of sampling, the operator leaves the scene to prevent the bacteria on the human body from being sucked in.
