Rotary evaporator manufacturer china
We are a manufacturer of rotary evaporators in China. Rotary evaporator is a distillation and extraction equipment. It is one of our main products. Our rotary evaporator includes: 2L rotary evaporator, 5L rotary evaporator, 10L rotary evaporator, 20L rotary evaporator, 50L rotary evaporator. We also provide auxiliary equipment: circulating water vacuum pump and cryogenic circulating pump.
Rotary evaporator, also called rotary evaporator, is a commonly used equipment in laboratories. It consists of a motor, distillation flask, heating pot, condenser, etc. It is mainly used for continuous distillation of volatile solvents under reduced pressure, and is used in chemistry and chemical engineering. , Biomedicine and other fields.
Structure principle
Structure: 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. 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.
The main components
1. Rotating motor: The evaporating flask containing the sample is driven by the rotation of the motor;
2. Evaporation tube: The evaporation tube has two functions. First, it plays the role of the sample rotating support shaft. Second, the sample is sucked out by the vacuum system through the evaporation tube;
s. Vacuum system: used to reduce the air pressure of the rotary evaporator system;
4. Fluid heating pot: Normally, the sample is heated with water;
5. Condensing tube: use double serpentine condensation or other condensing agents such as dry ice and acetone to condense samples;
6. Condensed sample collection bottle: After the sample is cooled, it enters the collection bottle.
The mechanical or motor mechanism is used to quickly lift the evaporating flask in the heating pot.
The vacuum system of the rotary evaporator can be a simple water suction pump immersed in a cold water bath, or a mechanical vacuum pump with a cooling pipe. The evaporating and condensing glass components can be simple or complex, depending on the goal of the distillation and the characteristics of the solvent to be distilled. Different commercial equipment will contain some basic features. Modern equipment usually adds functions such as political control of vacuum pumps, digital display of heating temperature and even steam temperature.
