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.

A Schlenk Line is a tubular glass apparatus commonly used in chemistry or material laboratory research to carry out experiments under a vacuum and an inert atmosphere (like nitrogen or argon). It is used when samples are sensitive to air/moisture and the vacuum is also often used to remove the last traces of solvent from a sample. A Schlenk ...

into the Schlenk manifold (pictured above) before exiting through a one-way gas bubbler. One-way bubblers are preferred because, in the event of an under-pressurization, they prevent the backflow of oil from the bubbler into the Schlenk manifold. Vacuum: A vacuum pump is connected to the upper line of the Schlenk manifold via a solvent trap. In the
