How does a rotary evaporator work?
Working principle and application.
A rotary evaporator is a piece of equipment commonly used in chemical, pharmaceutical, food and other industries to separate solutes from liquid substances through evaporation. Its working principle is to evenly coat the liquid substance on the wall of the container through a high-speed rotating cylindrical container, and then use a heating system to evaporate the liquid in the container to finally obtain the required solute.
Components.
The main components of a rotary evaporator include a cylindrical container, heating system, cooling system, vacuum system, rotating mechanism, collection bottle, etc. Among them, the cylindrical container is its core part. There are many pattern-like obstacles inside it, which can effectively increase the contact area between the liquid and the wall, thereby increasing the evaporation rate.
The heating system is to provide heat energy to quickly evaporate the liquid. The cooling system is to prevent the solution from overheating, thereby affecting the quality of the solute. The purpose of the vacuum system is to reduce the pressure within the system and thereby promote the evaporation process. The rotating mechanism is to rotate the container at high speed so that the liquid is evenly distributed on the container wall, thereby improving the evaporation efficiency. Finally, the collection bottle collects the liquid that evaporates from the container.
The working process.
1. First put the liquid to be separated into a cylindrical container, and then start the rotating mechanism to rotate the container at high speed so that the liquid is evenly coated on the wall of the container.
2. Then start the heating system to evaporate the liquid in the container, leaving the solute on the container wall. At the same time, the vacuum system is activated to reduce the pressure in the container, thus promoting the evaporation process. After the solute evaporates, it enters the cooling system as vapor and turns into a liquid, which is finally collected in a collection bottle.
Summary.
In short, a rotary evaporator is a device that uses a high-speed rotating cylindrical container to evenly coat liquid material on the wall of the container, and then uses a heating system to evaporate the liquid in the container to finally obtain the required solute. Its working principle is simple and efficient, can be used for the separation of various types of liquid substances, and has broad application prospects.
