Rotary Evaporator
A rotary evaporator is a laboratory instrument designed to gently and efficiently remove solvents from samples by evaporation.
Commonly used in chemical, pharmaceutical, and academic research laboratories, rotary evaporators are essential for processes such as solvent recovery, sample concentration, and purification.
Their ability to perform evaporation under reduced pressure makes them ideal for handling heat-sensitive substances while minimizing the risk of degradation.

Torontech's Range of Rotary Evaporators
Torontech offers a comprehensive selection of rotary evaporator for sale, tailored to meet diverse laboratory and industrial needs. Whether you require a compact bench-top model, a versatile lab-scale system, or a robust pilot-scale unit, Torontech has the right solution. Our rotary evaporator machines are designed for high performance, safety, and ease of use, with features such as precise temperature control, advanced vacuum systems, and durable construction.
1. Gentle Solvent Removal
By evaporating under vacuum at a low bath temperature, the rotary evaporator removes solvent without overheating heat-sensitive samples.
2. Rotating Evaporation Flask
Rotation spreads the sample as a thin film over the flask wall, which increases the surface area and speeds evaporation while preventing bumping.
3. Efficient Condenser
A cooled condenser recovers the evaporated solvent quickly, which improves recovery and keeps the process clean.
4. Controlled Heating Bath
A precise water or oil bath holds the chosen temperature steadily for consistent, repeatable distillation.
5. Vacuum Compatibility
The system works with a vacuum pump and controller to lower the boiling point, which allows faster evaporation at gentler temperatures.
6. Easy Flask Handling
A motorized or manual lift raises and lowers the flask into the bath safely, which simplifies setup and cleaning.
How Rotary Evaporators Work
The rotary evaporator consists of a rotating flask that holds the sample, a water bath to provide controlled heating, a condenser to cool and collect the evaporated solvent, and a vacuum system to reduce pressure and lower the boiling point of the liquid. This design enables rapid solvent removal while helping protect heat-sensitive samples.
As the flask rotates, the liquid spreads into a thin film over the inner wall, which increases surface area and speeds evaporation. The reduced pressure allows the solvent to boil at a lower temperature, and the vapor then passes to the condenser where it cools and is collected in a receiving flask. This combination of rotation, mild heat, and vacuum improves evaporation efficiency while reducing bumping and thermal degradation.
