Laboratory peristaltic pump is an important equipment widely used in scientific research laboratories, medical institutions and industrial fields. It plays a key role in the field of liquid transport with its unique working principle and excellent performance. This article will give you a detailed introduction to the working principle, characteristics, application areas and how to buy and maintain the laboratory peristaltic pump, to help you better understand and use this efficient, reliable and accurate liquid transfer tool.

First, the working principle

Laboratory peristaltic pump adopts the peristaltic principle, through the alternate compression and expansion between the peristaltic rotor and the pipeline in the pump head, to achieve the suction and discharge of liquid. Specifically, when the rotor moves forward, the pipe is compressed and the liquid is sucked in; As the rotor moves backwards, the pipe expands and the fluid is pushed out. This characteristic of peristaltic movement makes the laboratory peristaltic pump have the characteristics of high conveying accuracy and almost constant pump head resistance, and can precisely control the flow and pressure of the liquid.

2. Characteristics and advantages

1. Efficient and reliable: Laboratory peristaltic pump adopts advanced control system, which can achieve high precision and stable liquid transmission to ensure the accuracy of experimental results. At the same time, since the pump head is completely isolated from the liquid being transported, no cross contamination will occur, ensuring the reliability and consistency of the experiment.

2. Strong adaptability: Laboratory peristaltic pump can adapt to different types of liquids, including a variety of solutions, suspensions, high-viscosity liquids, etc. And the flow and pressure of the pump can be adjusted to meet the needs of different experiments.

3. Easy operation: the laboratory peristaltic pump uses an intelligent control system, with a humanized operating interface and operating guidelines, so that users can easily and quickly operate and control the operation of the pump.

4. Easy maintenance: the pump head of the laboratory peristaltic pump is easy to disassemble and clean, reducing the workload of maintenance and maintenance. At the same time, the pump head material is diverse, and the appropriate pump head material can be selected according to the characteristics of different liquids to extend the service life of the pump.

3. Application fields

Laboratory peristaltic pumps have a wide range of applications in the field of scientific research, including but not limited to the following:

1. Life science research: Laboratory peristaltic pumps can be used for liquid transport and trace reactions in biological experiments such as cell culture, protein purification, gene sequencing, etc.

2. Chemical analysis: Laboratory peristaltic pump can be used for liquid chromatography, gas chromatography, mass spectrometry and other analytical instruments in the solution transport and flow control.

3. Pharmaceutical process: Laboratory peristaltic pumps can be used for precise liquid delivery in pharmaceutical processes such as drug synthesis, drug delivery and drug testing.

4. Industrial field: Laboratory peristaltic pump is widely used in chemical industry, food, environmental protection and other fields, can be used for liquid mixing, feeding, transportation and other processes.

4. Purchase and maintenance

1. Select the right specifications: Select the right specifications and models according to the experimental requirements and liquid properties to ensure that the flow and pressure requirements of the experiment are met.

2. Pay attention to the material of the pump head: select the appropriate pump head material according to the characteristics of the liquid being transported, such as PVC, PTFE, etc., to extend the service life of the pump.

3. Regular maintenance: regularly clean the pump head and pipeline, and keep the pump in normal working condition. Pay attention to check the wear of the sealing ring and the peristaltic rotor, and replace it in time.

4. Reasonable use: Avoid overload work and long-term continuous operation, so as not to damage the pump head and control system.

Laboratory peristaltic pumps, with their efficient, reliable and precise liquid transfer capabilities, have become indispensable equipment in the laboratory and industrial fields. I hope this article will help you to understand the laboratory peristaltic pump and choose and use it reasonably in practice.
