2-5L Vacuum Rotary Evaporator
Components of a Vacuum Rotary Evaporator
A 2-5L vacuum rotary evaporator consists of several key components that work together to facilitate the evaporation process:
1. Heating Bath or Water/Oil Bath
- This component provides heat to the sample solution inside the rotary flask, facilitating the evaporation of solvents.
2. Rotary Flask
- The rotary flask, also known as the evaporation flask, holds the sample solution and rotates to increase the evaporation surface area, thereby improving efficiency.
3. Condenser
- The condenser collects the evaporated solvents and cools them to convert them back into liquid form, allowing for easy separation and collection.
4. Vacuum System
- The vacuum system lowers the pressure inside the rotary evaporator, reducing the boiling point of the solvents and aiding in rapid evaporation.
5. Cooling System
- The cooling system helps maintain the temperature of the condenser, preventing excessive heating and ensuring efficient condensation of the evaporated solvents.

Working Principle
At its core, a vacuum rotary evaporator utilizes the principles of heat and reduced pressure to separate solvents from samples. The sample solution is placed in the rotary flask, which is then rotated while being heated in the water/oil bath. As the solvents evaporate, they rise and enter the condenser where they are cooled and collected. The vacuum created inside the evaporator lowers the boiling point of the solvents, making the evaporation process faster and more efficient.
Advantages of a Vacuum Rotary Evaporator
A 2-5L vacuum rotary evaporator offers several advantages over conventional evaporation methods:
1. Increased Evaporation Efficiency
- The rotary flask's rotation and the vacuum environment enhance the surface area available for evaporation, resulting in faster and more efficient solvent removal.
2. Enhanced Heat Transfer
- The continuous rotation of the rotary flask ensures uniform heating, promoting better heat transfer and improving evaporation rates.
3. Solvent Recovery and Reuse
- By collecting and condensing the evaporated solvents, a vacuum rotary evaporator allows for solvent recovery and potential reuse, reducing costs and environmental impact.
