Laboratory Distillation Use Vacuum Rotary Evaporator

RE-52A rotary evaporator’s maximum capacity is 2000ml, rotate speed is 0-120r.p.m, motor power is 25W. RE-52A rotary evaporator use micro-motor to change speed, use lead screw up and down, hand wheel rotating makes main engine up and down. Rotary evaporator can rotate to form thin film and efficiently evaporation under thermostat heating and negative pressure, then cooling recycle the solvent, it is especially suitable for heat reactive material’s crystallization, separation and solvent recovery.

RE-52A rotary evaporator has following features:

1. Composed of reliable micro motor, speed measuring motor and integrated circuit, achieve stepless speed regulation of 0-120 rotate/min under the function of electronic speed governing; 

2. Use lead screw up and down, hand wheel rotating makes main engine up and down; 

3. Loosen cross-shaped bolt, main engine can arbitrarily lean within 0-15; 

4. Condensation system combines with head, it can lean with it and continuous feeding. The vertical efficient snakelike condenser makes it fast to condensate solvent and recovery rate approach to 100%; 

5. Digital display rotate speed and heating kettle’s temperature, it helps you observe parameter at a glance; 

6. Has the function of dry burning resistant protection and safe temperature loop; 

7. Wide speed adjustable range, can set speed freely between 0-120rpm; 

8. Smooth starting, can positive and negative inversion operate; 

9. Durable design, can choose plate bursting disk glass component as needed; 

10. Adopt closed resistance wire heating pipe, connect to temperature digital display, which can self turn-on or power off so as to automatic control the water temperature; 

11. Double sealed by PTFE and fluorine rubber sealing ring to keep high vacuum degree;

12. The water channel is made from excellent stainless steel, which can increase service life.

Rotary evaporator, also called rotavap or rotovap, is a commonly used lab instrument in chemistry laboratory, mainly used in continuous distillation of a large amount of volatile solvent under negative pressure. Especially for the concentration of extract liquor and distillation of receive liquid when chromatograph. Because evaporator is vacuumized, to be distilled solvent’s boiling point depressed. In general, ingredient which is distilled form sample is the target ingredient in chemical research, such as extracting some natural ingredient from organic synthesis sample. Rotary evaporator mostly is used for isolating low-boiling ingredient, such as hexane, ethyl acetate, that presenting liquid state under indoor temperature and normal pressure. Besides, it can dislodge some ingredient in sample by standard operation.
