Perkin triangle

<h2 id="solvent-drying">Solvent drying</h2>
<p>A Perkin triangle is also a convenient device for drying solvents. The solvent can be allowed to reflux over a drying agent housed in the still pot (shown as 2 in the figure) for a suitable time to dry solvent. The collecting tap (shown as 5 in the figure) can then be opened to collect the solvent in a <a href="/facts/Schlenk_flask/nAJ7W1I9">Schlenk flask</a> for storage. Depending on the boiling point of the solvent, a vacuum can be applied.
