Oilfree Vacuum Pump for Rotary Evaporator

Haico anti-corrosion diaphragm vacuum pump is used for evaporation, distillation, crystallization, drying, sublimation, filtration, decompression, degassing to provide vacuum conditions, as well as solvent recovery, various highly toxic, flammable and explosive, strong acid, strong alkali extraction, etc. With advanced design, high efficiency and long service life, it is a replacement product integrating high and new technology. In addition to the applicable occasions of circulating water vacuum pump and rotary vane vacuum pump, it is also used in the fields of medical and pharmaceutical product analysis, fine chemical industry, biochemical pharmacy, food inspection, criminal investigation technology, etc. It is a matching product for precision chromatographic instruments and one of the laboratory equipment.Application 1. Vacuum suction filtration 2. Vacuum distillation 3. Vacuum adsorption 4. Solvent filtration 5. Solid phase extraction 6. Degassing 7. For compressed and air conversion gas Characteristics of Haico diaphragm pump 1. There is no need for any working medium (no oil) and no pollution. At the same time, the gas exchange bin of this machine is equipped with filter materials, thus ensuring the purity of the air. 2. New technologies and materials are used in the production process. It is easy to move and works smoothly, thus ensuring ideal vacuum and high air flow rate. 3. The special motor has passed the EU CE certification and is provided by ODM, a professional export motor manufacturer. Reasonable rotation design, equipped with overheat power-off protector, automatically power-off after the pump body temperature reaches 130 ℃, to protect the motor from damage under long-term operation. 4. It adopts friction-free membrane movement, which does not generate heat and has no friction loss. The membrane adopts imported rubber, which is corrosion resistant and has long service life. 5. The machine body is designed with automatic cooling and exhaust system, which can ensure continuous operation for 24 hours. 6. The pressure adjustable design can meet the vacuum degree and gas flow rate within a certain range. 7. The bearings adopt imported classical bearings, which are stable in operation, low in noise and high in efficiency. 8. The parts of the anti-corrosion pump in contact with the gas are treated with Teflon, which has complete resistance to chemical corrosion. 9. Small size, light weight, convenient movement, saving laboratory space, convenient maintenance and repair. The anti-corrosion pump is characterized by that it is treated with Teflon, and the part in contact with the gas is made of PTFE material, which is resistant to strong acid and alkali, and is suitable for corrosive chemical, pharmaceutical, petrochemical gas, etc. This pump is applicable to vacuum filtration, vacuum distillation, rotary evaporation, vacuum concentration, centrifugal acceleration, solid phase extraction, etc. This is a cost-effective product with reliable quality and unique structural design, which is suitable for the needs of most experiments. Anti-corrosion PTFE features 1. It is corrosion resistant and can withstand almost all strong acids (including aqua regia), strong alkalis, strong oxidizing agents, reducing agents and various organic solvents. 2. It is resistant to high and low temperature, has little influence on temperature, and has a wide range of temperature range. PTFE material can withstand temperature of - 190~260 ℃. 3. The surface is not sticky, highly insulated, and highly lubricated. Most of the impurity particles cannot adhere to the surface.
