How do you set up a rotary evaporator?

Setting up a rotary evaporator involves several detailed steps to ensure efficient and safe operation.

8 Essential Steps to Set Up a Rotary Evaporator

How do you set up a rotary evaporator?

Preparation of Apparatus

Ensure that all components of the rotary evaporator, including the round-bottom flask, bump trap, and condenser, are clean and dry.

Temperature Control

Set the water bath to the desired temperature. The temperature should be appropriate for the solvent being evaporated.

Setup of Condenser

Connect the condenser to a cooling water source and allow the water to flow gently.

Loading the Flask

Fill the round-bottom flask with the solution to be evaporated. Secure the flask to the evaporator’s bump trap using a clip.

Positioning the Flask

Adjust the position of the flask using the joystick knob so that it is partially immersed in the water bath.

Activation of Vacuum Source

Turn on the vacuum source. This step is critical as it reduces the pressure inside the system.

Rotation of Flask

Switch on the rotation of the flask and adjust the speed to your preference.

Monitoring the Process

Close the stopcock on the evaporator. Monitor the solution to ensure it does not boil vigorously.
