5.5A: Overview of Rotary Evaporation - Chemistry LibreTexts

Aug 18, 2019 · The preferred method for solvent removal in the laboratory is by use of a rotary evaporator (Figure 5.65), also known as a "rotovap". A rotary evaporator is essentially a reduced pressure distillation: a solution in a round bottomed flask is placed in the water bath of the apparatus (Figure 5.66a), and rotated while the system is partially .

Rotary evaporator - Wikipedia

A rotary evaporator (or rotavap /rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.When referenced in the chemistry research literature, description of the use of this technique and equipment may include the phrase "rotary evaporator", though use is often rather signaled by other language (e.g., "the sample was .

Rotary evaporator for binder recovery, Asphalt/bituminous .

The apparatus is used for the recovery of soluble bitumen from bituminous pavement materials in a form suitable for further testing. During operation, the solution of solvent and asphalt (bitumen) from a prior extraction is distilled by partially immersing the rotating distillation flask of the rotary evaporator apparatus, in a heating oil bath while the solution is subjected to high vacuum .
