The chiller is normally set to 20 CIf you need to change this temperature for some reason do not set it below 15 CTo change the temperature rotate the knob located on the front of the chiller.
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.
Buchi 204060 rule for Rotary Evaporators 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.
How the rotary evaporator works is summarized below.
5L heating bath with a wide temperature range room tempTo180C independent temperature controlmake it can be used separatelyWateroil heating mode can be changed only through a switchManual lift combined with auxiliary lift for precise positioning of the glasswarePID control ensures high temperature accuracy at 1C.
Feb 14 2022 Rotary evaporators rotovaps are devices employed for removing solvents efficiently via the process of evaporationThe rotary evaporation process is one of the most widely used methods of solvent evaporation due to its optimal extraction and distillation performanceRotary evaporators are also used for concentration crystallization drying.

Mar 02 2016 A good general guideline to follow is the Rule of 20.
Mar 25 2019 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.
May 30 2019 Rotary Evaporators Rotovaps require cooling and ideally a recirculating chiller if sized correctly supplies accurate and precise coolingIt is true that a rotary evaporator does not require a chiller but for temperature accuracy and convenience purposes a chiller provides an effective and costefficient cooling.
Oct 11 2019 Rotary Evaporation Temperatures A vacuum pump lowers a solvents boiling point by reducing pressure within the rotary evaporatorThe water bath is deployed at 3040 degrees with an ethanol vapor temperature 1520 degrees CLower water bath temperatures prevent thermal decomposition.

The EV311H rotary evaporator features a manual glasssware lift and LED displaysThe micro lifting switch ensures easy locking and elevatingRotation speed and bath temperature of evaporating process can be easily adjusted by controller and is shown on the digital display.
The purpose of using the rotary evaporatorWe use the rotary evaporator rotovap for two main purposes 1To concentrate nonvolatile components in a mixture for example concentrating the purest and freshest flavors from a blood orange by removing the water 2To extract the volatile aroma and flavor molecules from mixtures gently and at.
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 Rotavapor 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 C.
Therefore the water bath temperature control system of a rotary evaporator was studied using the recovery rate of phthalate esters PAEs as the indicatorThe results showed that when the temperature of the rotary evaporator was set at 40C the actual temperature range of the concentrated liquid would change from 2641 to 3941C.
