Optimal Distillation parameters for a rotary evaporator vary according to solvent in use 1Set water bath temperature to 60oC – It does not need to be higher 2The cooling water temperature should be below 20oCAdjust the needed vacuum for a solvent boiling point of 40oC according to list below.
Potential explosion risk if solvent vapors accumulate within the instrument housingAlways use the instrument in a well ventilated areaBeware of damaged or cracked glass parts2 Other hazards WARNING Certain solvents in or in the vicinity of the Rotavapor can form peroxides andor are highly inﬂ ammable.
Potential explosion risk if solvent vapors accumulate within the instrument housing• Always use the instrument in a well ventilated area• Beware of damaged or cracked glass parts.
Rotary evaporation is a technique most commonly used in organic chemistry to remove a solvent from a higherboiling point compound of interestThe rotary evaporator or rotovap was invented in 1950 by the chemist Lyman CThe primary use of a rotovap is to dry and purify samples for downstream applications.

Rotovap Solvent Table Rotary evaporator De QumicaA common basic operation in the organic chemistry laboratory is the removal of a volatile organic solvent from a reaction mixture or a process such as liquidliquid extractionAlthough this operation could in principle be performed by simple distillation the fastest and most convenient.
The 10liter rotavap is used in the extraction of solvents and the extracted solvents are in crystalline formsOther than distillations this machine purifies the solutions without bringing unwanted side effects such as higher billsIt can also be used in mixing solutions and also separating vaporsFurthermore the machine is used in the food industry in activities such as preservation processing and handling a wide variety of foods.
The 10liter tabletop rotavap has a spacious capacity so it is capable of evaporating large volume samples at onceIt also has a motorized water bath thus giving you the benefits of controls as well as minimizing errors that would arise during operationsFurthermore it has a speed and temperature display giving you easy visual operationThe appliance also has a PID temperature controller thus you are able to maintain accurate temperatures.
The equipment is suitable for any experiment involving distillation evaporation or separation of chemicalsIt is also good with biological samples since it has a short elution time hence the samples are not denatured.
The rotavap also features awesome mobility since it possesses sturdy swivel caster which assists in turning it aroundAdditionally the machine is durable since it has a solventresistant PTFE and Viton gaskets as well as a high borosilicate glass that is hightemperature resistant alkali resistantIt also has a quiet operation since its motors are extremely compact and they are also vibrationfree.
The solvents or low boiling compounds are removed by a simple distillationThe rotovap is designed to be operated under a vacuum to lower a compounds boiling point while heating the sample at the same timeA cold finger is used to condense the vapors to a liquid which are trapped in a separate flask.
