Rotary Evaporator Mixology

Rotary Evaporators Fisher Scientific.

A rotary evaporator is an essential toolAnd an investment in quality is an investment in the quality of your product.

A complete rotary evaporator is generally composed of the following parts which cooperate with each other and all play an essential role in the working process of a rotary evaporator.

A rotary evaporator rotovap or rotavap refers to a kind of equipment for solvent evaporation under reduced pressure which is composed of a vacuum system a heated water or oil bath a condenser and a motor that rotates the evaporation flaskAs its name suggests what is special is that the evaporation flask can rotate.

A rotary evaporator or rotavap is a piece of equipment that efficiently and gently removes volatile solvents from your product through evaporationThe main components of a rotavap are An evaporation flask which contains the sample materialA motor that rotates the flaskA vacuumsealed vapor pathway which draws vapor off the sample.

After gasphase substances got condensed into liquidphase the liquidphase substances will be transferred into the receiving flask which is the final destination of extracted substancesAnd then users will take down the receiving flask from the rotary evaporator equipment.

During the whole working process there is always a vacuum pump providing a vacuum environment for the rotary evaporator which guarantees the whole system work in a reduced environment and the automatic feeding system formed by the pressure difference between atmosphere pressure and vacuum pressure.

Feb 14 2022nbsp018332Rotary evaporators rotovaps are devices employed for removing solvents efficiently via the process of evaporation.

For the cannabis industry we recommend one model of rotary evaporator.

In both traditional chemistry labs and our culinary technology lab the rotary evaporator or rotovap is an instrument used to distill a solventEveryone calls it a rotovap even though rotovap is a brand nameThe purpose of distillation is to separate a given mixture into its components based on their respective volatilities through the process of evaporation and condensation liquidgasliquid.

In order to achieve the highest possible solvent recovery rate several individual rates of the rotary evaporation process must be tuned to match or complement each otherThe defining characteristic of continuous operation is the slow and constant addition of fresh solution into the rotary flaskOnly as much solvent as can be evaporated and condensed should be added to the rotary flask per unit of timeIn other words the volume solvent dripping off the condenser should be equal to the volume of solvent containing solution dripping into the rotary flask.

Keeping the constants in mind there are several factors which must be tuned in order to achieve maximum recoveryThenbspΔTnbspfor each system is unique and largely dependent upon the refrigeration unit tuning the following rates to keepnbspΔTnbspfrom changing is the essence of continuous operation of a rotary evaporator.

Lucky molecular mixologists who can afford purchasing a Rotary Evaporator which costs over 6000 use this equipment to extract essential oils of a solid ingredient by boiling in a vacuum at low temperature without damaging the fresh aroma compoundsThe essential oils can then be mixed with other ingredients to be used in a cocktail.

What are Rotary Evaporators A rotary evaporator also called as rotavap or rotovap is a device used in labs for the efficient and gentle removal of solvents from samples by evaporationThe picture on the right shows what a typical rotary evaporator includes.

Rotary evaporator is an instrument used to distill a solvent generally is applied in chemical laboratory now is becoming  more an more popular in kitchen for family cooking.

The cannabis industry is one of the fastestgrowing markets in the world and its transforming before your eyesWhich makes it imperative to gain and maintain a competitive edge and set your brand apartThe right tools and the right partner can help you lead.

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 Rotavapor174 R300 meets the highest expectations of convenience and versatility in rotary evaporationIts modular design allows the R300 to be extended to a fully integrated system where a central interface regulates each componentEvaporating flask size 50 – 5000 mLLift mechanism Manual or automaticTemperature range 20 – 220 176C.

The working process of rotary evaporator is a consecutive process under a reduced environment.

These important constants are listed in order of increasing difficulty and cost to achieveHeating water is a very easy and low cost part of the system the vacuum pump is more specialized but relatively simple while the refrigeration unit is the most complex and costly componentHaving insufficient cooling capacity will dramatically decrease the maximum rate of solvent recovery possible from any rotary evaporation system.

This article explains the general process to achieve the maximum possible solvent recovery rate from any rotary evaporator.

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.
