A rotary evaporator[1] (rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.

Sep 21, 2023 · Rotary evaporators are used to extract essential oils from plants and herbs in the food, cosmetic, and fragrance sectors.

Mar 31, 2023 · How does a rotary evaporator work? How to evaporate ethanol from extract without rotary evaporator? A rotary evaporator is very important laboratory equipment mainly used for extracting, distilling, and purifying chemical samples. These are commonly known as Rotavap.

Begin rotating the flask at a medium rate by adjusting the rotation notch (to roughly 110rpm 110 rpm, or to one-third of the maximum rotation value, Figure 5.69b). Close the stopcock on the evaporator by turning it perpendicular to the bleed valve (Figure 5.69c).

Aug 15, 2021 · Rotary evaporation is the process of reducing the volume of a solvent by distributing it as a thin film across the interior of a vessel at elevated temperature and reduced pressure. This promotes the rapid removal of excess solvent from less volatile samples.

Mar 27, 2023 · A rotary type evaporator, also known as a rotovap or rotavapor, is a laboratory instrument used to evaporate solvents, usually from a sample in a round-bottomed flask. It is an essential tool in many chemistry and biology labs and is widely used in the pharmaceutical, chemical, and biotech industries.

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, and rotated while the system is partially evacuated (by a water aspirator or vacuum pump).

May 22, 2018 · Modern rotovap technologies support advanced methods which require precise temperature and pressure control, in addition to robust and demanding operation conditions. The concept of the rotovap entails motorized rotation of a solvent under reduced pressure.

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.

Rotovap chillers are specially designed. They have a much higher cooling capacity compared to refrigerated circulators. However, they usually don’t have as large of a temperature range. That’s because you won’t need extremely cold temperatures for evaporation: just a higher cooling capacity. The solvent vapor is warm when it hits the condenser.
