The rotary evaporator of our company has formed 2L 3L 5L 10L 20L and 50L series by collecting the essence of similar products at home and abroad and accumulating the successful practical experience of our rotovap distillation company The product design follows the principles of high efficiency practicality and economy Connect the secondary condenser with the gas guide bottle support it with a bracket and install a special PTFE gasket at the connection 6 Connect the collecting bottle with the secondary condenser hold it wiped film distillation with a bracket and install a special PTFE gasket at the connection 7 Insert the main condenser on the auxiliary condenser and fix it with the fixing clip 8 Installation extraction port feed valve and discharge valve 9 Install the rotating bottle on the machine head and press the locking button on the machine head to lock the rotating bottle 10 Place the water bath pot under the rotating bottle and add water to 2/3 of the pot Adjust the water bath height 11 Connect the joint above the vacuum meter with a vacuum hose at the exhaust pipe and connect the other joint to the vacuum pump 12 Connect the cooling water and feeding pipe Precautions for rotary evaporator 1 All glass parts shall be cleaned before installation 2 Apply a small amount of vacuum silicone grease on each standard port and sealing surface to increase the airtightness 3 Be sure to lock the bottle mouth bracket and machine head before the instrument works 4 Do not move the whole machine Application method of rotary evaporator The evaporation rate of the instrument depends on three conditions 1 The better the vacuum degree is rotary vacuum evaporator the faster the speed is The vacuum degree shall not be less than 0096 MPa during water evaporation 2 The higher the water bath temperature the faster the speed generally not more than 80 degrees according to the specific process requirements 3 The lower the cooling water temperature is the faster the speed is and the better the refrigeration effect is (I)
About motor temperature rise The motor of this instrument is a three-phase 220V special motor with E-class insulation The winding is made of polyester high-strength enameled wire The operating environment and altitude are not more than 1000 meters and the ambient temperature is not more than 40 degrees It is normal that the surface temperature of the motor (the difference between the surface temperature of the motor and the environment) does not exceed 45 degrees If the temperature rise exceeds 45 degrees check the relevant transmission lubrication system V Maintenance 1 Glass parts In case of serious dirt dilute sulfuric acid can be used for cleaning 2 Seal ring frequently check the wear degree of the seal ring and replace the worn seal ring in time to ensure the vacuum degree 3 Teflon interface In general it is not necessary to disassemble and wash If there is serious dirt it can be disassembled and washed 4 Water bath; if tap water is used Regularly clean the water stains on the electric heating coil To ensure good heating Return to Sohu to see more Responsible Editor toptiontech.com
