Rotary evaporation instrument is a medical, chemical, biological products, such as industry research and production in the process of evaporation, concentration, crystallization, drying, such as separation, solvent recovery process essential equipment.

Rotary evaporator is applied under the condition of vacuum negative pressure, constant temperature heating, thin film evaporation and the principle of research. The instrument adopts imported high-grade inverter control, stepless speed regulation to spin glass bottles of constant speed rotation, the formation of large area uniform thin film of wall material in the bottle, and then by the controllable constant temperature water-bath water of rotating bottle of uniform heating, in high speed under the condition of vacuum evaporation system, solvent vapor through efficient glass double condenser cooling, recycling in the collection bottle. The instrument also has charging interface and feeding mechanism, is advantageous for the automatic, continuous work in the process of evaporation.
