1. Brief introduction and Usage of rotary evaporators :

Rotary evaporators (also called rotovaps,vacuum rotary evaporator,rotary vacuum evaporator) introduces a new concept in routine distillation/evaporation processes,safety,efficiency and durability to support lab use work.They are used to remove solvent from reaction mixtures .


Rotary evaporator is mainly used for pharmaceutical, chemical and bio-pharmaceutical industry concentration, crystallization, drying, separation and dissolution of coal recovery.

Distillation of solvent

Concentration of solutions and suspensions

Crystalization or recrystallization

Synthesis and purifying of fine chemicals

Soxhlet extraction

Powder and granules drying

Recycling of solvent and so on

Rotary evaporators are found in almost every organic laboratory

They are mainly used for pharmaceutical,chemical and bio-pharmaceutical industry .
