A rotary evaporator has joint-pipe (20) of an evacuated double tube adiabatic structure. It is used, e.g. in a rotary evaporator or used with any evaporating apparatus having a heat-exchanging condensor, and avoids premature cooling and undesirable condensing of the solvent vapor ascending therethrough. Inside the joint-pipe, any reverse flow of the liquefied solvent vapor to a sample flask is .

Rotary evaporation is a technique commonly used in organic chemistry to remove a volatile solvent from a non-volatile compound of interest. Invented by Lyman C. Craig in 1950 the rotary evaporator, or rotovap, gently removes solvents from compounds using heat combined with reduced pressure to evaporate, dry, and purify samples for further downstream use.

celite and concentrated on a rotary evaporator to afford a yellow oil. The crude product was dissolved in THF/MeOH (6 mL, 1:1 v/v). K 2CO 3 (1.0 g; 7.30 mmol) was added and the reaction mixture was stirred for 2 h at 24 °C. The reaction mixture was diluted with ethyl aceate (10 mL) and washed with H 2O. The combined organic phases were .
UL and CSA Certification Now Available! The new Ai SolventVap series rotary evaporators are now UL/CSA compliant. This optional certification is required by many municipalities, and it also provides a higher standard of equipment safety and durability.
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 .
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 .
