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.


Rotary evaporator is mainly used for the concentration, crystallization, drying, separation and solvent recovery in medicine, chemical engineering and biopharmacy industry. Under vacuum condition, thermostat heating and make rotate bottle rotate in constant speed, material formed a large area thin film in bottle wall and evaporate efficiently. Solvent steam cooling by efficient glass condenser and collect to bottle, greatly enhanced the evaporation efficiency. Especially suitable for the concentration and purification of easily decomposed biological products.

RE-5299 is an essential basic instrument for analysis experiment in higher education units, medicine companies, chemical industry and scientific research units, beneficial for its small volume and electric or manual up and down electrical machine. The specific application as follows:

1.Medicine: various application in laboratory of quality control, research and development departments: distillation/concentration/drying;

2.Chemical: daily application in quality control and research laboratory: distillation/backflow reaction/re-crystallization/sublimation;

3.Education: widely application in academic education: comprehensive evaporation application;

4.Food/beverage: used for quality control and research of new ingredient: distillation/concentration/drying;

5.Environmental analysis: used for prepare supervision sample of environment pollution: Soxhlet extraction/concentration;

6.Fodder: used for quality control and research of new ingredient: distillation/concentration/drying.
