This article will provide a detailed introduction to the working principle of the Shanghai Yetuo rotary evaporator, including key elements such as the structure and function of the rotary evaporator bottle, vacuum control, and temperature regulation. At the same time, the application areas of rotary evaporators, such as organic synthesis, sample concentration, and pharmaceutical industry, will also be discussed. By delving into the working principle of the rotary evaporator, readers can better understand the importance and application value of the device in experimental research.

The Shanghai Yetuo rotary evaporator is a commonly used laboratory equipment for removing solvents and concentrating sample solutions. It has a wide range of applications in the fields of chemistry, biology, and pharmaceuticals. This section will briefly introduce the background and importance of rotary evaporators.

The core components of the Shanghai Yetuo rotary evaporator are the rotary evaporator bottle, heater, and vacuum system. Rotary evaporation bottles are usually made of glass and have a special shape that can hold sample solutions. The heater enhances the evaporation process by heating the sample solution in the rotary evaporation bottle. The vacuum system consists of a vacuum pump and a vacuum control device, used to create a vacuum environment during the evaporation process.

The working principle of the rotary evaporator is based on the evaporation of solvents and the movement of the rotary evaporator bottle. After the sample solution is placed in the rotary evaporation bottle, the rotary evaporation bottle begins to rotate. Through the action of rotation, the solution forms a thin film that is evenly distributed on the inner wall of the rotary evaporation bottle. At the same time, the vacuum pump creates a vacuum environment, reducing the boiling point of the solvent and promoting rapid evaporation of the solvent. When the solvent evaporates, the target substance in the sample solution gradually concentrates and deposits at the bottom of the bottle. In this way, through the rotation of the rotary evaporation bottle and the action of vacuum, the solvent can be quickly wiped away, thereby achieving concentration of the sample solution.
