How Does The Peristaltic Pump Work In The Laboratory?

  • by

Peristaltic pumps are widely used in the laboratory, such as chromatography, medium transport, tissue perfusion, etc. Let’s explore how peristaltic pumps work in these applications?


Chromatography is a kind of mixture separation technology, which is widely used in analytical chemistry, organic chemistry, biochemistry and other fields.

Chromatography can be applied to the determination of protein molecular weight, the separation and purification of protein, the determination of polysaccharide molecular weight, and the separation and purification of polysaccharide. Chromatographic column, detector, collector, peristaltic pump and other equipment are generally used for chromatography.

In the natural state, due to the permeation speed of the liquid in the chromatographic column, it is necessary to use appropriate external pressure to strengthen the permeability of the liquid, and at the same time, it is also necessary to ensure that there is no cross contamination during the liquid transportation.

The peristaltic pump can provide a certain fluid pressure to enable the fluid to smoothly pass through the chromatography column with large resistance (the smaller the pore of the packing, the greater the resistance); The fluid can pass through the chromatography column with high flow accuracy to achieve the expected chromatography effect.

The Reeve peristaltic pump has low shear force, which can reduce the damage to the effective components in the solution when pumping macromolecular solutions such as proteins.

2.Culture medium

The culture medium refers to the nutrient matrix prepared by the combination of different nutrients for the growth and reproduction of microorganisms, plants or animals (or tissues). It can not only provide the basic material for cell nutrition and cell proliferation, but also provide the living environment for cell growth and reproduction.

In the process of manufacturing and transporting the culture medium, the measurement shall be carried out according to different proportions, and the accuracy shall be strictly required.

Peristaltic pump can just meet these requirements. It is widely used in the laboratory. It is not only used for medium manufacturing, but also a good partner for medium loading and medium packaging.

Rev peristaltic pump has wide flow range and high transmission accuracy. It has the functions of timing measurement, distribution times, timing start and stop, etc. When the peristaltic pump transfers the medium, the medium only contacts the hose. It can ensure that the liquid is not affected by the pump body and the cleaning index is higher. Group

3.Tissue perfusion

Tissue perfusion is one of the experimental means of pharmacology or physiology research in medical colleges and scientific research institutions. For example, when studying the distribution area of neurons in the isolated brain tissue, in order to ensure the physiological activity of the isolated tissues and organs during the experiment, it is necessary to continuously deliver oxygen-containing culture solution to the isolated tissues or organs. This process is called tissue perfusion.

In vitro tissues or organs, external nutrient solution needs to be delivered to keep the activity. The Leifer peristaltic pump can set the rated flow and total delivery volume to continuously input the nutrient solution into the perfusion tank, so as to ensure that the tissues or organs can be in good physiological conditions.

At the same time, the waste liquid after irrigation can also be discharged in time through the peristaltic pump to keep the nutrient liquid stock in the irrigation tank balanced.

The Leifer peristaltic pump has reliable quality and stable performance, which can ensure the rapid replacement of the perfusion fluid in the perfusion tank, maintain the good physiological state of the isolated tissues and organs, and make the relevant experiments smoothly.

Lead Fluid peristaltic pump has the advantages of low shear force, high transmission accuracy, high cleanliness and stable performance. It is a good partner worthy of trust in the laboratory. Do you know which peristaltic pumps are used in the laboratory? Welcome to contact us.
