Rotary Evaporator

Laboratories carry out a wide variety of tests, experiments and endless chemical, medical and biological procedures; this characteristic of the laboratories makes the use of certain equipment to facilitate the activities carried out; one of these equipment is rotary evaporators; which are used in different areas and institutions such as: chemical industry, pharmaceutical industry, laboratories and hospital sector; they are also used in the manufacture and analysis of experiments to concentrate, dry and recycle. 

Rotary Evaporator is designed to evaporate organic or aqueous solvents; these equipment have a sample rotation system, revolution control and a thermoregulated bath to keep the sample at a controlled temperature; these characteristics of the apparatus make it indispensable in laboratories to be able to handle certain samples and to extract from them important aspects such as solute separation, extract flavorings from the samples, separate low boiling solvent.


Types of Rotary Evaporator a lab may need

Rotary Evaporator YR02307 // YR02310

The large capacity, wide aperture flask provides a larger evaporation surface. The evaporative flask continues to spin when constantly heated by a water bath, and the solvent evaporates more efficiently under vacuum conditions. Can be used for…


Rotary Evaporator YR02306

It is suitable for evaporation, distillation or chemical separation experiments. It usually works with a water circulation vacuum pump and recirculation cooler as a complete system to meet experimental and production requirements…


Our best-selling Rotary Evaporator

Rotavapor is an instrument that facilitates distillation; through the distillation flask it attaches to the evaporator tube that carries the solvent vapors into a coil-like coolant, once the vapors condense, the solvent is collected in the second flask, which serves as a collector; the rotary evaporator has a function that prevents the solvent from jumping violently while the vacuum is applied, called a rotary motor, this same procedure allows the inside liquid to moisten the surface of the flask and facilitates evaporation in a controlled manner.

At the same time the distillation flask can be heated externally through a thermostatic bath, thanks to a metallic arm that allows the whole assembly to go up and down; by attaching the distillation flask to the mouth of the rotary evaporator tube by means of a jack and holding with a clamp prevents it from falling into the water bath; continue distillation until vapor condensation is present in the collecting flask and the volume of the distillation flask content does not decrease further.

Process of using a Rotary Evaporator

Rotary Evaporator are certainly used for the process of removing organic solvent that occurs in a sample or the liquid-liquid extraction of a test; although there are several types of rotary evaporators, they all serve the same purpose, only some are better for certain applications; and although for these functions we can use a simple distillation equipment; with the rotary evaporator it is much more efficient and faster.

When Rotary Evaporator it is possible to attach a vacuum system that reduces pressure, another advantage is that it has a rotation system, which when rotated shows, the contact area is larger so evaporation is faster; if we want to list the reasons why rotary evaporation is essential in the laboratory, it has a controlled heating system that makes the process more efficient; so we can establish the importance of rotavapor compared to other equipment for distilling and heating samples; and perform the applications for which the rotary evaporator is used.
