Peristaltic pumps have become an essential tool in laboratory experiments due to their numerous applications and the advantages they offer. These pumps are commonly used in a wide range of scientific research fields, including chemistry, biology, pharmaceuticals, and medical research. The unique pumping mechanism of peristaltic pumps makes them particularly well-suited for various laboratory applications. As the top peristaltic tubing pump manufacturer in China, we would like share with you some applications of the peristaltic dosing pump in laboratory experiments.
A) Chromatography & Filtration
One of the primary applications of peristaltic pumps in laboratory experiments is chromatography and filtration applications. In chromatography, these pumps are used to deliver the mobile phase at a constant flow rate, ensuring optimal separation of analytes. Additionally, peristaltic pumps are commonly used in filtration setups to facilitate the filtration of samples or to maintain a constant pressure during filtration processes.
Chromatography is a type of mixture separation technology that is widely used in analytical chemistry, organic chemistry, biochemistry, and other fields. Chromatography can be applied to the determination of protein molecular weight, separation and purification of proteins, determination of molecular weight of polysaccharides, separation and purification of polysaccharides, etc. Chromatography generally uses chromatography columns, detectors, collectors, peristaltic pumps and other equipment.
In the natural state, limited by the penetration rate of liquid in the chromatography column, appropriate external pressure must be used to enhance the penetration capacity of the liquid, and at the same time, it is necessary to ensure that there is no cross-contamination during the liquid transportation process.
The Chonry peristaltic pump can provide a certain fluid pressure to allow the fluid to pass through the chromatography column with greater resistance smoothly (the smaller the pores of the packing, the greater the resistance); it can allow the fluid to pass through the chromatography column with higher flow accuracy to achieve the expected layer. analysis effect.
The Chonry peristaltic pump has a low shear force, which can reduce the damage to the active ingredients in the solution when pumping macromolecule solutions such as proteins.
B) Culture Medium
Another significant application of peristaltic pumps in the laboratory is the culture medium. Culture medium refers to a nutritional matrix prepared from a combination of different nutrients for the growth and reproduction of microorganisms, plants or animals (or tissues). It can not only provide cell nutrition and basic substances that promote cell proliferation but also provide a living environment for cell growth and reproduction. During the manufacturing and transportation process of culture media, measurement must be carried out according to different proportions, and strict requirements are imposed on accuracy.
The Chonry peristaltic pump can precisely meet these requirements. It is widely used in laboratories, not only for media manufacturing but also as a good partner for media loading, media dispensing, etc. Chonry peristaltic pumps have a wide flow range and high transmission accuracy. It has functions such as timing measurement, distribution times, timing start and stop, etc. When the peristaltic pump transfers the culture medium, the culture medium only contacts the hose. It can ensure that the liquid is not affected by the pump body when transporting liquid, and the cleanliness index is higher.
C) Organ Perfusion
Furthermore, peristaltic pumps are frequently employed in organ perfusion. Organ perfusion is one of the experimental methods used by medical schools and scientific research institutions to conduct pharmacological or physiological research. For example: when studying the distribution area of neurons in isolated brain tissue, in order to ensure the physiological activity of the isolated tissue or organ during the experiment, it is necessary to continuously deliver oxygen-containing culture fluid to the isolated tissue or organ. This process is called tissue perfusion.

For example: when studying the distribution area of neurons in isolated brain tissue, in order to ensure the physiological activity of the isolated tissue or organ during the experiment, it is necessary to continuously deliver oxygen-containing culture fluid to the isolated tissue or organ. This process is called tissue perfusion.
Isolated tissues or organs need to deliver external nutrient solution to maintain activity. Chonry peristaltic pumps and syringe pumps can set the rated flow rate and total delivery volume to continuously input the nutrient solution into the perfusion tank to ensure that the tissue or organ can be in good condition. physiological state. At the same time, the waste liquid after perfusion can also be discharged in time through a peristaltic pump to keep the nutrient solution in the perfusion tank balanced.
The Chonry peristaltic pump has reliable quality and stable performance, which can ensure the rapid replacement of perfusate in the perfusion tank, maintain the good physiological state of isolated tissues and organs, and enable related experiments to proceed smoothly.
In summary, peristaltic pumps have a wide range of applications in laboratory experiments. Their ability to precisely control the flow rate and volume of fluids, compatibility with various fluid types, gentle mixing capabilities, and suitability for chromatography and filtration make them invaluable tools in scientific research. By utilizing peristaltic pumps, researchers can ensure accurate and reproducible results, improve experimental efficiency, and maintain the integrity of sensitive samples or reagents.
