Product Details
Laboratory Rotary Vacuum Evaporator
(Dual Column Condenser Design)






How It Works: The Three Key Principles
Principle | How It Helps | Why Its Important | ||
Rotation | Spins the sample flask, spreading the liquid into a thin film. | Dramatically increases surface area for faster evaporation. | ||
Reduced Pressure (Vacuum) | Lowers the air pressure inside the system. | Lowers the boiling point of the solvent, allowing evaporation without high heat. | ||
Controlled Heating | Gently warms the sample flask in a temperature-controlled water or oil bath. | Provides energy for evaporation while keeping the temperature safe for sensitive compounds. | ||
As the solvent vaporizes, it travels into a cooled condenser where it turns back into a liquid and is collected in a separate flask for easy recovery and potential reuse. | ||||
