A rotary evaporator evaporates solvents from samples by utilizing the principle that the solvent will have a lower boiling point at a reduced pressure. Specifically speaking, the stepless speed regulation is adopted to make the evaporation flask rotate at a constant speed. By the rotation, materials can form a large area of uniform thin film on the inner wall of the flask. The evaporation flask is heated evenly by a water or oil bath, and materials, with a lower boiling point, is evaporated rapidly under the vacuum condition. The solvent steam is recycled in the receiving flask after being cooled by the high efficiency glass condenser.

Our Rotary Evaporators feature large easy to read digital and LCD & LED displays, controlling temperature, rotation speed and time. Some models feature motorized towers and range from 5L to 20L capacities. Vertical coil condenser or vertical dry-ice condensers are available for water and oil use to a maximum temperature to 180°C.
