A peristaltic pumps is used for pumping a variety of fluids, typically are used to pump clean/sterile or aggressive fluids because cross contamination with exposed pump components cannot occur. The fluid is contained within a flexible tube fitted inside a circular pump casing (though linear peristaltic pumps have been made). Laboratory peristaltic pumps depending on the function and pumped liquid can be divided into: Flow Rate Type peristaltic pump, Dispensing Type peristaltic pump, Industry Type peristaltic pump, Filling System and Mini Type peristaltic pump.
Advantages: No contamination: the only part of the pump in contact with the fluid being pumped is the interior of the tube, it is easy to sterilize and clean the inside surfaces of the pump.
Typical applications: Widely used in medicine and chemicals, such as oral liquid, diagnostic reagents, cosmetic dispensing, such as perfume, lip gloss, university research institutes, key Laboratory of environmental engineering etc.
