Select models with large surface area ensures a rapid evaporation process to remove solid residues. Receiving flasks feature ball or socket joints and a choice of jacketed, coated, or non-coated versions.
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.

Pear-shaped recovery flask is usually used as boiling type flasks for rotary evaporators. Laboy glass flasks are heavy wall designed, made by hand-blowing to ensure uniform wall thickness, made of high-quality borosilicate glass and annealed at 800 degree Celsius, can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating .
Only empty evaporation flask when as needed. This is called batch feeding the rotovap, you will be able to achieve the fastest times possible with this process. Note that any weak or inefficient hardware will either over heat, or stop working properly if you choose to go down the route of using the wrong / mismatched gear.
Rotary evaporator features a specially designed motor and worm gear, which provides constant rotation at speeds from 10 to 130 rpm. As the flask containing the solvent is rotated, it continually transfers a thin layer of liquid over the entire inner surface.
Rotary evaporators work by rotating the sample, thus coating the inside of the flask with solvent to increase the surface area available for evaporation is further sped up through the application of vacuum and heat. KNF's rotary evaporators are ideal for evaporating large volume samples in up to a 3 L flask.
Using a rotary evaporator. Empty and then replace the solvent collection flask on the unit. SAFETY FIRST! You don't want to accidentally mix incompatible chemicals. Place your flask on the rotary evaporator. Most people use a bump bulb to prevent their material from accidentally splashing into the condenser (and being contaminated).

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.
