Manifold, vacuum/inert gas

Evacuating and filling a Schlenk tube with an inert gas using a vacuum/inert gas manifold... [Pg.205]

Immediately equip the neck of the Schlenk tube with the septum and attach the side-arm to the vacuum/inert gas manifold via one of the flexible tubing connections. [Pg.206]

Adjust the vacuum/inert gas manifold to gas (Fig. 7.2c) and fill the Schlenk tube with nitrogen/argon. [Pg.206]

Adjust the vacuum/inert gas manifold to nitrogen/argon and fill the flexible tubing connection between the manifold and the Schlenk tube stopcock with inert gas. Still shaking the Schlenk tube gently, open the Schlenk tube stopcock and refill the Schlenktube with inert gas. [Pg.208]

Adjust the vacuum/inert gas manifold to vacuum and evacuate the flexible tubing connection between the manifold and the Schlenk tube stopcock. [Pg.209]

Support Schlenk tube B under its side-arm using a clamp and a stand with a heavy base. Fit it with a septum, attach it to the vacuum/inert gas manifold and evacuate it and refill it with inert gas (Protocol 1). [Pg.210]

Carefully pour the solvent system selected above to fill the column completely and fit the top of the column with a septum. Attach the side-arm of the column to the vacuum/inert gas manifold and adjust the vacuum/inert gas manifold to nitrogen/argon. Open the stopcock and compress the gel. Maintain the pressure until ail the air is expelled and the lower part of the column is cool. Note that the level of the solvent must always remain above that of the silica gel. [Pg.211]

Collect fractions in Schlenk tubes with inert gas flowing gently through them and concentrate using the vacuum/inert gas manifold (Protocol 3). [Pg.212]

Does the chemistry require the use of a vacuum/inert gas manifold Most modem synthetic laboratories have several manifolds dedicated to synthetic chemistry. As a result, most modem preparations assume that one will be available. As a result, if a vacuum/inert atmosphere manifold is not available for the proposed synthesis, each step must be carefully screened to ensure that one will not be needed. [Pg.3]
