Schlenk lines are supported by lattice lab frames that are secured to the back wall of the fumehood. It is recommended to secure the Schlenk line at a comfortable height with at least three clamps, securing both the vacuum and inert gas manifold to prevent slippage or tilting. Orient the clamp so that the weight of the Schlenk line is supported by the bottom (the non-moving arm) of the clamp – this means that the thumbscrew is always at the bottom or underneath the glassware being supported. This same principle should also be applied to boss heads.
The cold trap should also be secured to the lattice frames with a clamp after being suitably aligned with the vacuum manifold. For Schlenk lines with Teflon taps, the cold trap is commonly connected to the vacuum manifold with a greaseless O-ring ball and socket joint. For Schlenk lines with ground glass stopcocks, the cold trap is typically connected to the vacuum manifold through a ground glass joint that has been suitably greased or sealed with wax.
