Pollution free: The fluid only comes into contact with the pump tube and does not come into contact with the pump body, which can avoid cross contamination. It is suitable for transporting fluids with high hygiene requirements such as food, medicine, cosmetics, etc. High precision: By controlling the roller speed or using a stepper motor, high-precision flow control can be achieved, with high repeatability and stability accuracy, suitable for situations that require precise measurement. Low shear force: The fluid moves almost smoothly inside the hose, and has a good transport effect on shear sensitive and highly corrosive fluids, such as solutions containing cells and high viscosity colloids. Good sealing: It has good self-priming ability, can rotate freely, can prevent backflow, and can easily transport solid, liquid or gas-liquid mixed phase fluids. Pump tube selection: Select appropriate materials and sizes of pump tubes based on the chemical properties of the fluid being transported and the working conditions of the pump, ensuring that they have a certain degree of elasticity, wear resistance, ability to withstand pressure, and good airtightness., Manufacturer: CHUOZI
