The key to understanding any distillation is to remember that it is a separationSugars acids colors and most bitter compounds are separated from aromas alcohols water and small flavor molecules etcWhat is phenomenal about rotovap distillation as opposed to standard distillation is that it can separate food compounds from one another without altering them.

The rotary evaporator is used mainly for two cooking purposes to concentrate the nonvolatile constituents in a food mixture and to extract the volatile flavors and aroma constituents from a food mixtureA rotary evaporator is an ideal distillation apparatus different from other conventional distillation apparatus as it is capable of separating food components from one another without affecting any of the food componentsThis makes it ideal and more popular for home cooking.

The Rotary Evaporator It is commonly taught in General Chemistry classes that the vapor pressure of a liquid or solid varies directly with temperature ithe higher the temperature of a substance the higher its vapor pressure.

The setup of a rotary evaporator The first step is to pour the solvent mixture and the compound you want to work on in a round bottom flaskIt is advisable to fill the flask less than a half if you want to get the desired results.

Laws were written to prevent people from not paying taxes on distilled liquorSince I have already paid alcohol taxes on 100 of the products I use and I don’t ship or resell them at a higher proof I feel I am adhering to the spirit if not the letter of the lawI have heard people say that the distillation laws are also in place to prevent accidents conventional distillation with open flames can be quite hazardous but I disagreeI’m allowed by law to light a cigarette and bungee jump off a bridge over a tanker of kerosene if I want to.

Two key components of the rotovap allow for a gentle precise and efficient distillation not found in conventional distilling apparatuses 1 the solvent is removed under vacuum which lowers its boiling point eliminating the need for hightemperature distillation and 2 the rotation of the evaporating flask immersed in a heated water bath increases the surface area of the product greatly speeding distillation and also through forced convection keeping the mixture evenly mixed and heated to promote stable even evaporation.
