Polyscience Rotary Evaporator

The main working principle of polyscience rotary evaporator is to use the combined effect of centrifugal force, vacuum environment, and heating generated by rotation to rapidly evaporate liquid samples.

When the rotating cup rotates at ultra-high speed, the liquid sample will be thrown onto the wall of the rotating cup due to centrifugal force, forming a thin film. At the same time, the heater heats this thin film to quickly evaporate. The evaporated gas and water vapor are continuously extracted by a vacuum pump to maintain a low-pressure state inside the evaporator. In this process, due to the maintenance of vacuum degree and temperature control, it is possible to effectively avoid problems such as oxidation and decomposition of liquid samples during the evaporation process, thereby obtaining high-quality evaporation products.

The vacuum environment of the ultra high speed rotating vacuum evaporator can effectively reduce the influence of air on liquid samples and obtain purer evaporation products.

At the same time, a vacuum environment can also increase the evaporation temperature and accelerate the evaporation rate by reducing the air pressure. These characteristics make the high-speed rotating vacuum evaporator an indispensable and important equipment in fields such as chemistry, biology, and medicine.

◆ Rotational action

The rotation effect of the multi science rotary evaporator is not only to evenly distribute the liquid sample on the inner wall of the rotary cup. The centrifugal force generated by this rotation also causes the liquid sample to form a thin film on the inner wall of the rotating cup, and the thickness and uniformity of this film can be controlled by adjusting the rotation speed. Due to the rapid outward movement of the liquid sample, the evaporation process is more efficient, and this thin film can also increase the contact area between the liquid sample and the heat source, further improving the evaporation efficiency.

In addition, the rotational effect of the high-speed rotating vacuum evaporator also causes the molecules in the liquid sample to continuously collide with the inner wall during the movement process, increasing the molecular kinetic energy and thus improving the evaporation rate. This high-speed rotating evaporation method can evaporate a large amount of liquid samples in a short period of time, which is very suitable for experiments that require a large amount of solvent evaporation.

◆ Vacuum environment

The vacuum environment of polyscience rotary evaporator is one of its most important characteristics, which can greatly reduce the influence of air on liquid samples. Evaporation in vacuum can prevent liquid samples from being affected by substances such as oxygen and moisture in the air during the evaporation process, resulting in purer evaporation products.

Firstly, a vacuum environment can effectively prevent the oxidation of liquid samples. In the air, many liquid samples will react with oxygen, leading to oxidation reactions that alter their chemical properties and molecular structure. In vacuum, the liquid sample does not come into contact with oxygen, so its original properties can be maintained.

Secondly, a vacuum environment can also reduce the influence of moisture and other impurities in liquid samples. During the evaporation process, moisture and other impurities may react with substances in the liquid sample, or only occupy the evaporation space, thereby affecting the evaporation rate and product purity. In vacuum, these impurities can be effectively removed, resulting in purer evaporation products.

In addition, a vacuum environment can also increase the evaporation temperature by reducing the air pressure. Under normal pressure, the evaporation of liquids requires the absorption of heat, so a certain temperature is required to achieve it. In vacuum, due to the decrease in air pressure, the boiling point of the liquid also decreases, so evaporation can be achieved at lower temperatures. This can not only accelerate the evaporation rate, but also protect the thermosensitive substances in the liquid sample from high temperature damage.
