In the laboratory, how to choose an efficient and reliable flow pump has attracted much attention. As a special pneumatic pump, Peristaltic pump is used by more and more laboratories. Peristaltic pump flow is efficient and reliable, can withstand various chemical media, protect the integrity of experimental materials, is an indispensable tool in the laboratory.

The peristaltic pump is a pipe sandwiched between a rubber rotor and a compression plate. The rotor continuously compresses the pipe through the action of the compression plate, pushing the fluid forward. Therefore, the peristaltic pump will not have the phenomenon of leakage, there is no risk of gas-liquid mixing, reducing the possibility of experimental contamination and cross-contamination, in addition, the experimental material will not come into contact with the pump itself, protecting the integrity and purity of the experimental material.

The flow of peristaltic pump is reliable, accurate, not easily affected by environmental factors such as temperature and pressure, and can meet the various requirements of the laboratory in different precision and different flow ranges, so it is widely used in the field of experiment, analysis, research and development.

The selection of peristaltic pump needs to pay attention to the following aspects:

1. Flow requirements: Different experiments have different requirements for flow, so different types of pumps should be selected according to the flow requirements specified in the specific experiments.

2. Accuracy requirements: peristaltic pump can achieve the function of flow reversal, so the flow size can be changed, but it is necessary to consider the accuracy of the flow required by the experiment, and choose a peristaltic pump with high-precision function.

3. Fluid characteristics: the peristaltic pump can withstand various chemical media, but the material of the pump body and pump pipe should also be selected to avoid experimental pollution.

4. Pressure range: peristaltic pump has different performance in different pressure ranges, and it is necessary to choose a pump suitable for the experimental requirements.

The use of peristaltic pump also needs to pay attention to the following points:

1. Before use, ensure that the pump pipe and pump head are clean and clean to prevent contaminants from affecting the test results.

2. In use, the flow rate, pressure and other parameters of the pump should be adjusted in time according to the experimental requirements to ensure the smooth progress of the experiment.

3. After use, clean the pump head and pump pipe in time to avoid impurities and pollutants, which will destroy the service life of the pump.

In summary, the peristaltic pump is popular as an efficient and reliable flow pump in the laboratory. In the selection of peristaltic pump, it is necessary to choose the appropriate peristaltic pump model according to the requirements of the specific experiment and fluid characteristics. At the same time, before, during and after use, it is also necessary to pay attention to various details to ensure the normal operation of the peristaltic pump and provide stable and reliable flow support for the experiment.
