World Panorama

A rotary evaporator, or rotavap, works by heating liquids under low pressure, vaporizing them and condensing that gas in a separate vessel, just like many other distillation apparatus. However, a rotavap uses both temperature and pressure changes in its functionality.

Cleavage of the Graft Bonds in PVDF–g–St Films by Boiling .

The homopolymer formed in the monomer solution was collected by removing the monomer and the solvent by using a rotary evaporator at 60 °C for 5 h. About 570 mg of homopolymer formed in the monomer solution was collected, which suggests that most of the styrene was not polymerized and remained in the solution during the graft polymerization.

Rotary Evaporation to Remove Solvent | Protocol

Rotary evaporation is a technique commonly used in organic chemistry to remove a volatile solvent from a non-volatile compound of interest. Invented by Lyman C. Craig in 1950 the rotary evaporator, or rotovap, gently removes solvents from compounds using heat combined with reduced pressure to evaporate, dry, and purify samples for further downstream use.

How to select lab vacuum pumps for high vapor-flow .

Apr 27, 2017 · In contrast to rotary evaporators, concentrators are less likely to get condensation in the vacuum tubing because the vacuum is mainly what induces the evaporation. (The speed of the rotor can elevate internal temperatures in the concentrator to 35˚C.) So the considerations are the same with respect to the need for gas ballast and its impact .

Soxhlet extractor - Wikipedia

A Soxhlet extractor is a piece of laboratory apparatus invented in 1879 by Franz von Soxhlet. It was originally designed for the extraction of a lipid from a solid material. Typically, Soxhlet extraction is used when the desired compound has a limited solubility in a solvent, and the impurity is insoluble in that solvent. It allows for unmonitored and unmanaged operation while efficiently .
