Dec 16, 2019 Connect one socket to the rotovap (where the evaporation flask would usually go). You can secure it in place or hold it with one hand. Note, the flask should not be set to spin during this process. Use your thumb to close the second socket of the two-neck flask. Set the vacuum pump to around 250 mbar and switch it on.
Dec 22, 2020 To flush a rotary evaporator with acetone, fill up a small two-neck flask around halfway with acetone. Then, connect one socket of the flask to the rotary evaporator where the evaporation flask is typically located. Either hold the flask by hand or secure it to the machine. To close the second socket of the two-neck flask, hold your thumb over it.

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.
Rotary evaporation is accomplished using a rotary evaporator, also known as a rotovap or rotavap. It is a commonly used technique for separating a compound of interest from a low-boiling solvent, such as an organic, inorganic, or polymeric substance. Separation is accomplished by heating a mixture of solvent and compounds inside an evaporation ...
