Power on the hot water bath and set the temperature to approximately 30°C or lower. This will gently heat the flask during evaporation.
▶ 00:26
2
Enable cooling and water flow
Close the air inlet on the rotovap bath and turn on the cold water to begin cooling the condenser.
▶ 00:38
3
Generate vacuum with water aspirator
Turn on the water aspirator to create a vacuum inside the system. Ensure the tap is fully open to achieve proper pressure reduction.
▶ 00:48
4
Attach splash trap and flask
Attach the splash trap to the rotor valve, then attach your round bottom flask containing the solution and product. Hold firmly until pressure exceeds 40 on the manometer.
▶ 01:06
5
Rotate flask and apply heat
Enable the rotation function and gently rotate the round bottom flask. Lower the flask into the hot water bath for gentle heating during evaporation.
▶ 01:48
6
Stop rotation and cool compound
Once solvent evaporation is complete and crystals have formed, turn off the heater and gently lift the flask out of the hot water bath. Stop the rotation function.
▶ 02:14
7
Release vacuum and disassemble apparatus
Hold the round bottom flask securely and release the vacuum. Remove the glassware from the rotor valve.
▶ 02:42
8
Shut down system and collect solvent
Turn off the water aspirator and cooling water flow. Empty any residual solvent from the receiving flask.
