Rotary Evaporator

Rotary Evaporator

A rotary evaporator (or rotavap)[1] is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. ... (For instance, both DMF and DMSO will boil below 50 C if the vacuum is reduced from 760 torr to 5 torr [from 1 bar to 6.6 mbar]) However, more recent developments are often applied in ...

good correlation with the evaporation rates observed for the in-line evaporator.9 Removal of high boiling solvents such as water, DMF, DMSO, pyridine and N-methyl-2-pyrrolidone (NMP) is extre-mely slow and consumes large amounts of energy using stan-dard rotary evaporators. In a typical reaction work up it is

High boiling point solvents like DMF (boiling point:

High boiling point solvents like DMF (boiling point: 153 C), DMA (boiling point: 165 C) and DMSO (boiling point: 189 C) are often used for drugs synthesis. In an attempt to remove small amount of DMF (around 5 ml) used as solvent for small scale Pagoclone synthesis (an anti-anxiety drug) through rotary evaporation with a water bath, large ...

Putting the Rule of 20 Into Practice Blog -

May 08, 2020 In general, your bath temperature should be 20C higher than the boiling point of the substance you want to evaporate. And your coolant should be 20C or more lower than the vapor temperature. For example, if the boiling point of your substance is 40C, a bath temperature of 60C and coolant temperature of 20C should provide an optimal setup.

Thin films of lipids are prepared by rotary evaporation from solutions in dichloromethane (CH 2 Cl 2).The lipid film is rehydrated with an aqueous solution of the reactant and/or other additives and agitated at a temperature above T c until the film has completely detached from the flask (Fig. 12.4).This results in the separation of the lipid sheets, which close on themselves to form a ...
