Components of Manual Rotary Evaporator

01/

Rotary motor
A rotary evaporator consists of an electric-powered motor that plays an important role by rotating the evaporation flask at a continuous and constant speed. This results in an increased surface area for evaporation as well as even mixing, heating hence a stable and even evaporation.

02/

Vacuum source
This is the system responsible for creating a vacuum within the airtight set-up, thereby reducing the pressure within the system. The vacuum source can be simply a water aspirator consisting of a water immersed trap, or a complex mechanical vacuum pump consisting of a refrigerated trap.

03/

Glass tube
The glass tube has two functions, the first is to protect and support the sample during rotation while the second is to help in the creation of a vacuum.

04/

Heating bath
The mainly used heating bath is a hot water bath. The function of the heating pot is to heat the sample and help in temperature regulation.

05/

Condenser
It is mainly found in a double snake shape and the function is to condensate the evaporated sample as well as enhance convenient sample collection.

06/

Receiving flask
The function of the collecting flask is to receive the distilled sample.

Multiple Uses of Manual Rotary Evaporator

Solvent Evaporation
The primary use of manual rotary evaporator is to distill large amounts of volatile solvents under reduced pressure continuously. The reduced pressure in the system lowers the boiling point of the solvent, making it easier to evaporate.

Sample Concentration
Manual rotary evaporators are used to concentrate samples by evaporating off solvents. It is common in biology, where it is often necessary to concentrate a sample before analysis or to recover a solvent for reuse.

Crystallization and Precipitation

By carefully controlling the evaporation process, manual rotary evaporator can be used to drive crystallization or precipitation processes, enabling the purification or isolation of specific components from a mixture.

Powder Drying

Manual rotary evaporator can be used to dry powders or granules without causing agglomeration, which can occur with other drying methods. It is particularly important in the pharmaceutical industry, where maintaining the integrity of active ingredients is necessary.

Recycling of Solvent

In industries where the same solvent is used repeatedly, manual rotary evaporator can be used to recycle solvent, reducing waste and saving money.

FAQ

Q: What factor decides the working efficiency of manual rotary evaporator?

A: For products of the same specification, the major factors include the steam temperature, the vacuum degree and the cooling water temperature. Restricted by bad heat resistance of some materials, the steam temperature cannot be improved indefinitely while working. The high vacuum degree and low cooling water temperature are two main factors to improve the working efficiency. (The cryopump can be selected to lower the temperature.)

Q: What's the working principle of manual rotary evaporator?

A: The principle is that the boiling points of liquids can reduce with the decreasing pressure. As a result, the solvents are capable of being vaporized at much lower temperature than their boiling points at the normal pressure.During the operation, the rotating flask is heated thermostatically and can rotate at a constant speed. Then the material forms a large area of thin film on the inner surface of the flask. The solvent vapor is recycled in the collecting bottle after being cooled by high-efficiency glass condenser.
What's the feature of manual rotary evaporator comparing to other Compared to other evaporators, the manual rotary evaporator is compact, efficient and easy to observe, with no metal ion pollution. It's used for laboratory test, pilot production and the extraction of valuable materials. The sealing performance is comparable to those made in foreign countries. But the appearance and the humanization design still have some room for improvement.
