Various Applications of Peristaltic Pump in Lab

Jun. 12, 2023



The peristaltic pump is the best solution for liquid transfer, especially in Laboratory. Today we would like to share different uses of peristaltic pumps in the Lab. Chonry is a leading peristaltic pump manufacturer in China. CE and IS9001 certified. 30+ patents and 200+ products. If you are interested in it. Inquire peristaltic pump now!

1. Laboratory application-ultrafiltration system

The application of the peristaltic pump in the ultrafiltration system is generally a small-scale ultrafiltration experiment, which can be widely used in concentration (polymers, cells, microorganisms, viruses, etc.) separation and clarification filtration. The peristaltic pump connects the sample and the ultrafilter and transfers the sample to be filtered into the ultrafilter.

Function: The peristaltic pump connects the sample and the ultrafilter, and sends the sample to the ultrafilter to perform the ultrafiltration experiment.


a. The action is gentle, and there is no rigid extrusion or shear to the product.

b. The inner wall of the flow channel is smooth and smooth, without sharp corners that cause cell damage.

c. No toxicity, corrosion resistance, and no foreign matter falling off.

d. Small size, reliable performance, can adjust the flow, and adjust the forward and reverse rotation as needed.

e. Easy to clean and disinfect.

2. Ion Chromatography

Ion chromatography (IC) is a method that uses the principle of ion exchange to continuously separate, characterize, and quantify coexisting multiple anions or cations. When analyzing cations, the separation column is filled with a low-capacity cation exchange resin and hydrochloric acid solution is used as the eluent.

Especially suitable for the determination of low-concentration anions in aqueous solutions, such as drinking water quality analysis, high purity water ion analysis, mineral water, rainwater, various wastewater and power plant water analysis, pulp and bleach analysis, food analysis, biological fluid And blood, etc.), and applications in the iron and steel industry, environmental protection, etc. Ion chromatography can determine the following types of ions: organic anions, alkali metals, alkaline earth metals, heavy metals, rare earth ions, and organic acids, as well as amines and ammonium salts. Typical ion chromatography application examples.

The advantages of a peristaltic pump:

No pollution: the fluid only touches the pump tube, not the pump body

Low shear force: conveys shear-sensitive and corrosive fluids

Good sealing: good self-priming ability, can be idling, can prevent backflow.

3. Scientific research

Peristaltic pump for Scientific research. Mixing different fluids stream together after the peristaltic pump and letting them crystallize.

An operation method in which separation is carried out by a crystallization method by using a difference in solubility of each component in the same solvent or in a case of cold and heat.

As long as crystals are formed, the purity of the compound is of comparable purity. Crystallization is one of the important methods for refining solid compounds. The crystals precipitated for the first time are often impure, and the process of making the pure crystals into impure crystals is called recrystallization.

The peristaltic pump acts as a dosing and solubilizing agent during the crystallization process.

Advantages of peristaltic pumps:

a)No pollution: the fluid only contacts the pump tube and does not touch the pump body;

b) high precision: repeatability, high stability; 

c) Low shear force: It is an ideal tool for conveying shear-sensitive and aggressive fluids;

d) good sealing: has a good self-priming ability, can be idling, can prevent backflow;

e) simple maintenance: no valves and seals;
