Manual for Rotary Evaporator

I. Introduction of usage

Rotary evaporator is a kind of device with the operation principle as follows: put the rotary

evaporation bottle (flask used to increase the evaporation area) in water bath under the
condition of reduced pressure, and make it rotate while heating it, so as to make the solution in
the bottle diffuse and evaporate. It is a relatively ideal basic instrument necessary for the
concentration, drying and recycling relied on by the production and experimental analysis which
is conducted by the chemical industry, pharmaceutical industry, universities and colleges, and
research laboratories and so on.

II. Structural features

1. Rotation of principal machine
The principal machine consists of a group of reliable micro-motors, speed motors and
integrated circuits. Under the action of electronic speed control, it can realize the stepless
speed regulation within the range of 0-150 r / min.

2. Elevation of principal machine
RE-52AA-type principal machine adopting the method of micro-motor speed change can be
automatically ascended and descended only by pressing the switch with hand. The elevation is
