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.
Evaporator mempunyai dua prinsip dasar, untuk menukar panas dan untuk memisahkan uap yang terbentuk dari cairan.

Bagian-bagian dari alat rotary evaporator 1. Water bath dan hot plate 2. Labu alas bulat tempat pelarut yang menguap dan labu alas bulat tempat sampel ...
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.
