3. To close the system and thus activate the vacuum, turn the stopcock knob at the far end of the rotovap to align it with the vacuum (ie. turn until the arrow on the knob points straight down towards the attached tubing ie. knob is pointing to the “ON” position). The system is now under reduced pressure. 4.
