5 Litre Lab Chemical Rotary Vacuum Evaporator Stainless Steel Frame

A rotary evaporator (rotovap or rotatvap) refers to a kind of equipment for
solvent evaporation under reduced pressure, which is composed of a vacuum
system, a heated water or oil bath, a condenser and a motor that rotates the
evaporation flask. As its name suggests, what is special is that the
evaporation flask can rotate.
A complete rotary evaporator is generally composed of the following parts,
which cooperate with each other and all play an essential role in the working
process of a rotary evaporator.


1. Better security.
The stainless steel and aluminum alloy are widely used in the mechanical
structure, and all glass parts are made of heat-resistant high borosilicate
glass, which ensure a better security. Besides, the water/oil bath can be
equipped with transparent covers to prevent splashing, and anti-explosion
frequency changer and dynamo are available as well. All of these designs
contribute to better security.

2. Higher evaporation efficiency.
There are several factors contributing to higher evaporation efficiency.
Firstly, the rotating flask can rotate at a constant speed, and materials can
form a widespread film on the inner surface of the flask, which improves the
evaporation efficiency greatly. Secondly, the high-efficiency glass condenser
can improve the evaporation efficiency as well. Last but not least, continuous
feeding and high vacuum degree are another factors.

3. More convenient operation.
It's much more convenient to use a rotary evaporator, because the electrodeless
speed regulation, digital display K type sensor and intelligent temperature
control and other designs adopted by it.
