Rotary evaporator is an evaporation instrument in the laboratory. It consists of a motor, a distillation bottle, a heating pot, a condenser tube and other parts.

  1. Unattended mode with safe operation function, which is in automatic standby mode after the experiment
  2. Vacuum protection design which prevents vapor from vacuum pump, so the vacuum pump is more durable
  3. Sealing made up of imported PTFE with special technique
  4. DC rotating motor of 70w power starts steadily
  5. Vertical condenser with drip point design prevents backflow
  6. Intermittent positive and negative rotating function with timer function for drying process
  7. Oil and water heating bath with safe handle, whose temperature range is from room temperature to 210℃
  8. Anti-dry auto-lifting and automatic standby function
Rotary-Evaporator details
  • Big color LCD screen with menu interface displaying several data; rotary switch easy to operate
  • Both touch screen control and button press type automatic lifting function
Special design of bottle
  • Special design of bottle pulling switch, which is easy to disassemble the evaporation flask(only REV-2000AX)

Temp. range/precision Microcomputer PID controller; Water Bath:RT.-99℃±0.5℃;Oil Bath:RT.-210℃±2℃
Bath Material Integral Teflon compound heating bath with safe handle, which prevents from scald; the medium sized bath volume makes distillation fast.
Bath Size φ23*13cm(about 5.4L) φ26*15cm(about 8L) φ29*17cm(about 11L)
Positive&Negative Rotating Intermittent positive and negative rotating function with timing function (0-60s) for drying process.
Lift Automatic balance lifting which can be controlled by either button-press or Color LCD screen; the lifting length is 150mm, with fixed safety distance of 60mm, which prevents crashing.
Temp. Set Rotating switch coding for temperature setting with big LCD screen display.
Safety Anti-dry prevention function which makes flask automatic lifting; instrument will stop at the set timing (0-999min); automatic lifting and standby alarm protection in abnormal or over temperature state.
