Is rotary evaporator distillation?

Rotary evaporation is a technique most commonly used in organic chemistry to remove a solvent from a higher-boiling point compound of interest. The rotary evaporator, or "rotovap", was invented in 1950 by the chemist Lyman C. Craig. The primary use of a rotovap is to dry and purify samples for downstream appliions.

2. The flask with the solution is placed on the rotary evaporator. The use of a bump trap prevents the solution from accidentally splashing into the condenser (and being contaminated). It is highly advisable to start with a clean bump bulb in case something bumps over after all! This would allow the experimenter to recover the solution or solid. 3.

Rotary Evaporator Bump Traps - Safety Emporium

Product Description. These are the most traditional rotary evaporator bump bulbs/traps which are used between the vapor tube and evaporation flask on a rotary evaporator to prevent the contents of the flask from being drawn into the condenser in the event of solvent bumping.

After filling the cold traps, you then have to attach a glass bump trap to prevent the solution from entering into the main part of the rotary evaporator. This is made firm by securing it with a Keck clip. After attaching a Keck clip, attach the pump trap and the flask to the adaptor of your rotary evaporator.

Rotary evaporator - Wikipedia

In particular, bumping can often be prevented by taking homogeneous phases into the evaporation, by carefully regulating the strength of the vacuum (or the bath temperature) to provide for an even rate of evaporation, or, in rare cases, through use of added agents such as boiling chips (to make the nucleation step of evaporation more uniform).
