Low temperature coolant circulating pump


Also supports L/C,D/A,D/P,T/T,Western Union,MoneyGram payments for offline orders.


RE-201D Rotary evaporator is a small scale rotary evaporator. The maximum capacity of the evaporating flask is 2L, and the maximum capacity of the collecting flask is 1L. It is suitable for continuous or intermittent distillation and extraction of materials under normal pressure or vacuum conditions, and is especially suitable for heat-sensitive materials. Concentration, crystallization, separation and recovery are essential basic instruments for chemical, pharmaceutical, universities, scientific research laboratories and other units.

Rotary evaporator usually consists of four parts:
Glass parts
Water bath parts
Sealed parts
Motor parts

Glass part:
All use high borosilicate glass, the physical and chemical properties are more prominent.

2L rotary evaporator

Condenser: The rotary evaporator evaporates the liquid under constant temperature control. The evaporative airflow returns to the condenser. After constant temperature cooling, it is converted into liquid and then returned to the recovery bottle. The condenser plays an important role.

Evaporating flask: The evaporating material is placed in a rotating flask, and usually the solvent capacity cannot exceed half of the evaporating flask capacity.

Receiving flask: the material extracted by distillation is stored in the receiving bottle.

Water bath parts:
Provide a heating source for the materials in the evaporating flask. Different types of rotary steamers have different powers in the water bath.

Sealed parts:
The flange is made of rubber wood and PTFE, which has strong hardness, high temperature resistance and more wear resistance.

Motor part:
1) Adopt international standard copper wire.
2) Long continuous operation time and good stability.
3) CE certification.

The usual supporting equipment for rotary evaporator:
Circulating water vacuum pump: Vacuuming provides a vacuum environment for material reaction. It is divided into two types: desktop (SHZ-D) and vertical (SHZ-C). You can choose and match according to the type of rotary evaporator.
