introduction

The Rotary evaporator is a commonly used Laboratory equipment, which is used to remove solvents and concentrate sample solutions. It has extensive applications in the fields of chemistry, biology, and pharmaceuticals. This section will briefly introduce the background and importance of the Rotary evaporator.

Structure and composition of Rotary evaporator

The core components of the Rotary evaporator are the rotary evaporation bottle, heater and vacuum system. Rotating evaporation bottles are usually made of glass and have a special shape that can accommodate sample solutions. The heater enhances the evaporation process by heating the sample solution in the rotating 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.

operational principle

The working principle of the Rotary evaporator is based on the evaporation of solvent and the movement of the rotary evaporation bottle. After the sample solution is placed in the rotating evaporation bottle, the rotating 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 rotating 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. During solvent evaporation, the target substance in the sample solution gradually concentrates and deposits at the bottom of the bottle. In this way, by rotating the evaporation bottle and applying vacuum, the solvent can be quickly wiped away, thereby achieving the concentration of the sample solution.
