The Applications and Features of Rotary Evaporator
What is rotary evaporator? How to use it? Why it is very necessary to use this equipment? People may often think a series of questions and this reactor is often applied as laboratory instrument evaporator. It is said from http://www.toption-china.com/rotary-evaporators/ that this device is mainly used in pharmaceutical, chemical and biopharmaceutical industries including concentration, crystallization, drying, separation and solvent recovery. It is said that this equipment was invented by Lyman C. Craig. Moreover, it also has important effects on removing solvents from reaction mixtures and they are found in almost every organic laboratory, because they allow performing this task quickly. Generally speaking, the typical equipment usually has a water bath that is heated by using a metal container and crystallization dish. As we all know, the main components of the device may include motor unit, vapor duct, vacuum system, condenser and other components. What’s more, it can keep the solvent from freezing during the evaporation process and the solvent is removed
under vacuum. Meanwhile, it can’t be advised to be used for air and water-sensitive materials unless there are some special warnings that are taken. Actually, the rotary evaporation is regarded as the process of reducing the volume of a solvent across the interior of a vessel. Generally speaking, the solvent distillation flask will be heated with a heating bath to reach certain temperature that is the boiling point of the solvent accessible. And the evaporator is more used in a lot of continuous distillation under reduced pressure. In order to increase the evaporation area, a constant rotational speed may be reached at the most suitable speed of flask. As a matter of fact, the work principle is that large area thin film material is formed in the sidewall, by constant temperature heating, constant speed rotation of the rotating bottle, and efficient evaporation under vacuum conditions. The basic principle is that it may distill under reduced pressure while the distillation flask can go on rotating as solvent is distilled. More importantly, the evaporator develops the crucial effects on continuous distillation under reduced pressure. Moreover, it can also be in the vacuum state by vacuum evaporation flask that is placed in a rotary evaporator while heating thermostat water bath. And the heating temperature is the boiling point of the solvent accessible. Maybe many people hear that this evaporator is very fit for being used for reflow operation or a large number of rapid evaporation of the solvent. Mention again, it develops the significant role in pharmaceutical, chemical and bio-pharmaceutical industry, drying, dissolution of coal recovery etc. Certainly, there are some usage of rotary evaporators are not mentioned in above. Meanwhile, it is the process of reducing the volume of a solvent. Actually, the rotary evaporation can promote the rapid removal of excess solvent from less volatile samples and the evaporator is the use of vacuum and constant temperature heating conditions, and high evaporation equipment installations. For year, the evaporator equipment plays an important role in our lives and we should not ignore its wide applications.
