Digital rotary vacuum evaporator
The distillation flask is an eggplant-shaped or round-bottomed flask with a standard ground mouth interface. It is connected to a pressure reducing pump through a high reflux serpentine condenser tube. The other opening of the reflux condenser tube is connected to a receiving flask with a ground mouth. Used to receive evaporated organic solvents. There is a three-way piston between the condenser tube and the decompression pump. When the system is in communication with the atmosphere, the distillation flask and the wetted flask can be removed to transfer the solvent. When the system is in communication with the decompression pump, the system should be in decompression. 压State. When in use, the pressure should be reduced first, and then the motor should be turned on to rotate the distillation flask. When it is finished, the machine should be shut down and then vented to the atmosphere to prevent the distillation flask from falling off during rotation. As the heat source for distillation, it is often equipped with a corresponding constant temperature water tank.
1,the moveup and down lift system adopts motor revolved lifting structure.
2,the condenser adopted two kinds of optional structure , one is double line convection principle, the other one is a single line with interlayer water, ice, and dry ice container. Used in organic solvent evaporation. And the vertical condenser saves space.
3, the axis of rotation use high temperature high borosilicate glass, heat resistant and good sealing. Sealing parts use teflon + teflon two-way sealing, and the effect is good.
4, it is equipped with heating trough, and built-in resistance wire heater, heating temperature is from room temperature to 99 ℃.
5, the device is equipped with temperature indicator, intelligent temperature controlling, digital display, temperature control implemented by PT100 sensors. When the water temperature reaches primary temperature, the controller automatically cut off the heater power; When is lower than the water, temperature controller automatically turn on the heater power; To realize the tank water temperature be constant.
6, B type, E type is equipped with speed display, can accurately display rotation speed, E type is LCD screens.
Rotators consists of a set of stable and reliable micro motor, speed motor and integrated circuit control device. In the role of electronic speed, it can rotating steadily in 10-180 RPM range, it has reached the advanced level at home and abroad.
