92# Peristaltic dosing Pump Tube for Chemicals

Peristaltic Dosing Pump Tube:The main factors for selecting tubing:  Tubing’s characters: • Good flexibility, quick recovery after pressure (shore hardness:40-80) • Abrasion resistance. • Common press-endurance • No leakage (good air-tightness),low adsorption. • Good temperature-endurance and aging-resistance • No swelling, corrosion resistance • Low precipitate
Size:  The size of the tubing direct influence on the flow, the inner diameter of the tubing decided the flow, is directly proportional to the flow. Wall thickness not only influences the resilience of tubing, but also influences the life of the tubing.     Transparency:  Whether or not adopt transparent tubing, first look at whether the operator needs observe the status of tubing fluid at any time. Check the fluid is whether sensitive with the light. If the operator needs observe the status such as: the bubbles, particles, pollution case, should choose the Tygon® or silicone rubber tubing, and if the fluid is not easy to exposure, should choose not transparent tubing.     Gas permeability:  For some fluid is sensitive with the gas, some easy by oxidation, or anaerobic cell cultures. Users should consider the gas permeability factor of tubing. In general, the highest porosity is silicon tubing. So some fluid that unfavorable contact with the gas, should choose the low porosity of tubes.   The authentication:  Tubing is used for related purposes may be through the relevant authentication. Such as the United States pharmacopoeia USP, European pharmacopoeia EP, the United States food and drug administration standard FDA, the United States department of agriculture standard USDA and the national sanitation foundation standard NSF.   Working life:  Different tubes have different abilities of roller extruding, friction resistance. Different tubing type, pipe, pump head, operation speed, the life are different. Choose the long life, thick wall tubing, big flow pump, run in lower speed can be obtained more long service life.   Flow range:  Each tubing is corresponding fixed flow range, we according to our customers needs of flow range choose corresponding tubing.
It can be widely used in GMP pharmaceutical, biotechnology, molecular biology, fine chemical, environmental protection, food processing and other areas of scientific research and production.
