Original Title: Usage of Rotary Evaporator/Rotary Evaporator Rotary evaporator/rotary evaporator is a kind of distillation device commonly used in laboratories, which is widely used in many industries and scenarios. But many people don't know much about the use of rotary evaporation instruments. Today I will share with you briefly. Rotary evaporator/rotary evaporator 1. Rotary evaporator/rotary evaporator host height adjustment: manual lifting, hand holding head sliding up and down or hydraulic rod rotating host lifting up and down; electric lifting, with (double insurance: film button and rocker button) and up and down buttons,jacketed glass reactor, hand touch up button host lifting, hand touch down button host lowering; 2. There are two external joints on the rotary evaporator/rotary evaporator condenser,rotovap distillation, which are connected to the internal serpentine pipe for cooling water. One end is connected to the inlet water, and the other end is connected to the outlet water. Generally, tap water is connected. The lower the temperature of the condensed water is, rotary vacuum evaporator ,nutsche filter dryer, the better the effect is (it can be equipped with a low-temperature cooling circulation device). One of the nozzles is connected with the internal straight pipe for vacuumizing, which is used for vacuumizing by the vacuum pump hose; 3. Turn on the main power supply. Before starting the machine, turn the speed control knob to the left to the end, press the power switch indicator light, and then slowly turn it to the right to the required speed. Generally, medium and low speed are used for large evaporation bottles, and low speed is used for solutions with high viscosity. Flask is standard interface 24 # or 29. If the attached flask is not enough, it can be purchased separately. Generally, the amount of solution is not more than 60%; When using: turn on the cooling water first (if the cooling effect of tap water is not good, the material will be pumped away by vacuum, and a low-temperature circulation device is needed), then start to reduce the pressure,cbd crystallization equipment, adjust the heating temperature you need, generally set half of the boiling point of the material + 5C ° under the vacuum degree of about 0.095 MPa, and then start the motor to rotate the distillation flask; 5. At the end ? The rotating motor of the rotary evaporator/rotary evaporator should be stopped before the atmosphere is opened to prevent the distillation flask from falling off and the vacuum pump from sucking back during the rotation.
