50L Rotary Evaporator Rotovap for efficient and gentle removal of solvents from samples by evaporation Item include all the parts showed on the photos A rotary evaporator or rotavaprotovap is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.
Always turn the rotovap off before adjusting the equipmentKeep the rotovap in the fume hood to prevent inhalationOnce the evaporation is complete conduct the same steps in the reverse order turn off the hot water bath remove the flask from the water stop the rotation turn off the vacuum.
Below is a photograph of a rotary evaporatorImportant Features of the Rotovap1 The vacuum pump is the source of reduced pressure in the system2 Spin speed and bath temperature control knobsPlease do not use the rotovap if the finger is not cold.
Dimethyl sulfoxide DMSO is a polar aprotic solvent that can dissolve a wide range of organic compoundsThe high dissolving power of DMSO makes deuterated DMSO DMSOd6 a common solvent for NMROne of the major drawbacks of DMSO is the difficulty of removal after a reactionIts high boiling point 189 C makes removal by rotovap very difficultDMSO is also used as a reagent in a variety of different reactions.
Jan 10 2014nbsp018332To rotavap DMF Dow Corning high vacuum grease must be freshly applied to the joins and Keck clips used to hold the flask onto a nonreversible splashguardWith the water bath at 55 176C the vacuum will need to be lowered to 25 Torr at 70 176C the required vacuum is only 25 TorrA 100 mL preweighed flask and a 500 mL nonreversible splash.
