A rotary evaporator(rotovap) is a device commonly used in chemical laboratories for the efficient and gentle removal of the volatile solvents from samples by evaporation. They are found in almost every organic laboratory. The rotation flask rotates and shapes a thin film in negative pressure condition by heating; it evaporates; and then the vapor is condensed, liquefied, and recollected for separation.

A typical thin film evaporator has a water bath that can be heated in either a metal container or crystallization dish. This keeps the solvent from freezing during the evaporation process. The solvent is removed under vacuum, is trapped by a condenser, and is collected for easy reuse or disposal.


Rotary evaporators are distillation units that incorporate an efficient condenser with a rotary flask system. As the flask containing the solvent is rotated it continually transfers a thin layer of liquid over the entire inner surface. This gives a very large surface area for evaporation that is effected by heating from the accessory water or oil bath.

Low temperature cooling liquid circulating pump


High and low temperature circulating pump

  • Rotary evaporator matching use with circulating water vacuum pump to offer a vacuum environment for reduced pressure distillation, they are widely used for vacuum filtration, vacuum evaporation, vacuum degassing, etc..
  • Rotary evaporator matching use with GDSZ series high and low temperature circulating pump to quickly cooling or warming, the circulating pump is an efficient equipment for quick temperature adjustment.
  • Rotary evaporator matching use with DLSB series low temperature cooling liquid circulating pump to conduct chemical reaction and medicine storage which requires low temperature environment.

Features of  rotary evaporator

  • Highly Chemical Resistance-All components that make contact with liquids and gases are made of borosilicate glass 3.3 and PTFE.
  • Specialized motor with extremely compact, intermeshed worm and worm gear provides precise driving for very quiet, vibration-free operation.
  • Downward-condensing vacuum connection design ensures safe vacuum operation
  •  Modular design (individual rotary and water bath modules) for extremely easy maintenance and easy future upgrades
  • Easy auto lift with secure lock for the evaporating flask
  • Easy, straight-forward and visual operation with digital speed and temperature display
  • PID temperature controller ensures accurate temperature control is maintained
  • 1-way check valve automatically turns off when draining the receiving flask. The pressure inside evaporator won’t be changed during draining.
  • Digital display of temperature and rotation speed
  • Heavy-duty SS304 support frame and epoxy-coated water/bath enclosure guarantees vibration-free operation.
  • Various options and accessories are available (vacuum pump, chiller, vacuum controller, cold trap, etc)
  • One year warranty on rotary evaporator except for glassware and all sealing gaskets.

Advantages of 100L rotary evaporator

  • Rotary evaporator’s equipped thermostat water bath kettle , keep glass part fixed and cut down damage; when evaporating in low boiling point, collecting bottle also can immerse in ice bath so as to reduce twice evaporation;
  • Beauty in appearance, clear number of vacuum meter;
  • Adopt main and vice efficient condenser, there has automatic switching device between vice condenser and receiving bottle. Below receiving bottle, equipping with tapping valve, which makes it convenient to recycle solvent and the recovery rate approach to 100%;
  • Sealing system is anti-corrosion under high temperature, long service life;
  • Among standard bottle neck glass there has PTFE clamp cover, which can prevent glass ground seizure;
  • Collecting bottle use ground connection, which has excellent performance and is easy to dismount;
  • 0-110 rotate/speed governing, digital display of rotate speed;
  • Its rotate bottle use ISO29 standard bottle neck, which can easily take off by thread and weaken glass damage, solved the problem of difficult to take off bottle under high temperature;
  • Its bath kettle’s temperature control range is between 0-399℃, can be used as water bath kettle and oil bath kettle, temperature fluctuation is only ±0.2℃, more stable evaporation, no spark control, much safer.
  • Silence design, optimal experiment environment;
  • The vertical condenser has strong mobility, three choices are available, it can equip with cold trap to do low boiling point evaporation collection.

Application of 1ooL rotovap

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.

100L rotary evaporator has a large capacity of 100L, designed for the purpose of mass production need, is mainly used for pilot plant production in biology, chemical engineering, pharmacy and food industry.
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.
