Rotary Evaporator

The RV131 Rotary Evaporator stands out in many advantages. It comes with a large LED display and touch keys, along with an adjustable knob that helps you easily set and monitor parameters. The double-layer vertical condenser with 1500cm² cooling surface provides efficient vapor collection and sample recovery. The PID controller ensures precise temperature control.


The Rotary Evaporator, also known as rotovap, is a laboratory equipment for liquid distillation and purification. It is widely used in chemical, pharmaceutical, biotechnology industries and R&D labs to separate and concentrate samples. It usually works with  Diaphragm Vacuum Pump and  Recirculating Chiller  as a whole system to meet the production and experimental requirements.







● Large LED display to easily set and monitor process parameters

● The touch keys and adjustable knob let you easily set the rotation speed, heating temperature, operation time, and cycle times (clockwise and/or counterclockwise cycles).

● The device also comes with a mistouch prevention lock to avoid changes through accidental touch

● The adjustment knob can be turned fast or slow to change parameters rapidly or accurately.

● The 5L water-oil heating bath with heating temperature range of up to 180℃ (oil)

● The device comes with a Brushless DC motor with rotation speeds ranging from 20 to 320 rpm

● Comes with PID temperature controller, overheat protection, dry-burning protection, and automatic power-off functions

● Double-layer vertical condenser with 1500cm² cooling surface for efficient vapor collection and sample recovery

● High elastic graphite filled PTFE seal and compression spring bring excellent sealing as well as high-temperature, corrosion, and abrasion resistances.

● Manual lift for precise positioning of the glassware; the lifting height ranges up to 180mm and the tilt angle range is 0-360° (evaporation flask can be positioned on the left or right side)

● Ejection mechanism ensures easy removal of evaporating flask
