A rotary evaporator (rotovap) is a fast and effective method of removing solvent from a flask. A rotovap removes solvent by reducing the pressure within the flask using a vacuum, rotating the sample to increase its effective surface area, and heating the solution.

The Rotary Evaporator

bath to spread a thin film of solution on the inner surface of the round bottom flask. This encourages more rapid evaporation and minimizes a phenomenon known as 'bumping - an intermittent, uncontrolled boiling. The on-off switch is located at the upper left on the rotovap motor and the speed control knob below it.

What is Crystallization? - Rotovap

Dec 20, 2019 The rapid cooling and evaporation will make the solution reach the supersaturation state quickly, and even reach a relatively high supersaturation by directly going through the meta-stable zone to obtain a large quantity of tiny crystals. Otherwise, the slow cooling and evaporation can usually get large crystals.

Rotary Evaporation to Remove Solvent Organic Chemistry ...

The rotovap mechanically rotates a flask containing the compound in solution in a heated water bath. The rotovap is connected to a vacuum pump that reduces the pressure above the bulk solvent facilitating the draw of the evaporate away from the sample. The solvent evaporates while the compound remains.

How does rotary evaporation work? -

The rotovap works by increasing the rate of evaporation of the solvent by (1) reducing the pressure to lower the solvent boiling point, (2) rotating the sample to increase the effective surface area and (3) heating the solution. To use the rotovap, first make sure that the power is on (top right of the stand).

Distill the future: why should you care about rotovaps?

This process begins by adding a solution to a starting flask. Parallelly, a water bath is prepped. Both the solution and water bath are retained at the same temperature and the vacuum pump is switched on to put the system under pressure. ... The rotovap is a leap beyond traditional distillation methods as it can accurately capture the essences ...
