A rotary evaporator,also known as a spin distiller,is a commonly used piece of laboratory equipment for the continuous distillation of volatile solvents under reduced pressure.Rotary evaporator as a laboratory and production of commonly used evaporator products,with excellent distillation extraction performance has been recognised by the majority of users.Today I come to explain to you the rotary evaporator working principle and structural characteristics,I hope this article can help users better apply our products.
Rotary evaporators are widely used in the fields of chemistry,biochemistry,pharmaceuticals,etc.They are especially suitable for solvent removal of heat-sensitive substances.By rotary evaporation,rapid and efficient solvent evaporation and sample concentration can be carried out at lower temperatures.
What is the working principle of rotary evaporation apparatus?
The rotary evaporator works simply by electronically controlling the distillation flask to rotate at a constant speed at a suitable speed to increase the evaporation area.At the same time through the vacuum pump to make the evaporation flask in a negative pressure state.Evaporation flask in the rotation at the same time placed in a water bath at a constant temperature,the solution in the bottle under negative pressure in the rotating flask for heating diffusion evaporation.The evaporation system can be sealed and depressurised to 400 to 600 mmHg;the solvent in the distillation flask is heated with a heating bath to a temperature close to the boiling point of the solvent;it can also be rotated at 50 to 160 rpm to form a film of solvent to increase the evaporation area.In addition,under the role of efficient cooler can be quickly liquefied hot vapour to speed up the evaporation rate.The above is the working principle of rotary evaporator.
What is the structure of a rotary evaporator?
After introducing the working principle of rotary evaporator,let's take a look at what its structure is.The main six parts of the composition,respectively,is the condenser tube,collection bottle,evaporation tube,rotary motor,vacuum system and bath.Among them,the condenser tube using double serpentine condensation,adding condensate such as dry ice,acetone to condense the sample;collection bottle effective recovery of condensed samples,samples cooled by the collection bottle and was collected;evaporation tube first play the role of the sample rotating support shaft,followed by the evaporation tube through the vacuum system will be sucked out of the samples;rotary motor through the motor's rotation driven by the evaporation of samples held in bottles;the vacuum system is used to reduce the rotary evaporator system The vacuum system is used to reduce the air pressure of the rotary evaporator system;the back bath is used to heat the sample with water or oil as medium.
