Rotary Evaporator

A rotary evaporator (sometimes abbreviated to rotavap) is a piece of equipment primarily used to remove solvent from a sample through “evaporation under reduced pressure”. The presence of reduced pressure in the apparatus causes the solvent (in the round bottom flask) to boil at a lower temperature than normal.

Why Do We Use Rotary Evaporator? - WKIE

A rotary evaporator allows for a precise and gentle distillation conventional machines cannot provide. The main reason why rotary evaporators are better than traditional devices is that it removes the solvent under vacuum. Vacuum lowers the boiling point, therefore eliminating the need for high temperature for the distillation process to occur.

How Does a Rotary Evaporator Work - USA Lab

Mar 01, 2021 Rotary evaporators are a widely used tool in many laboratories—from chemical to biology laboratories. Also known as rotavaps, the primary purpose these useful instruments serve is to remove solvents from a mixture through the process of evaporation.

How Does a Rotary Evaporator Work - USA Lab

Mar 01, 2021 To begin the process of rotary evaporation, a solvent is placed in a round-bottomed flask in the water bath of the rotary evaporator system. The system’s pressure is then reduced below atmospheric pressure through the use of a vacuum pump. Reducing the pressure in the rotary evaporator has numerous benefits. Namely, the reduced pressure ...

Falling Film vs. Rotovaps: the fracTron solution - extraktLAB

Mar 10, 2020 A thin film improves mass transfer and speeds evaporation while a vacuum is used to decrease the boiling point of the target solvent. The key difference between a rotovap and a thin film is in how that film is created and how much throughput can be produced. In the case of a falling film evaporator there is a series of vertical bundles of metal ...

Do Rotary Evaporators Need Chillers? - BV Thermal Systems

May 30, 2019 Why use a Rotary Evaporator? A rotary evaporator is often utilized because it is the fastest and most efficient method to remove low boiling organic chemicals from a mixture of compounds. The rotovap works by employing three simple methods. The first is to increase the rate of evaporation of the solvent by reducing the pressure to lower the ...
