Stopcock: 2mm glass stopcock with spring retention device for smooth turning.
Why a Spring-Retained Glass Stopcock
A plain ground-glass stopcock can loosen or stick over repeated use, especially where a reaction needs precise, repeatable control of addition. The spring retention device on this flask's 2mm glass stopcock keeps consistent contact pressure on the ground joint, giving smoother turning and a more reliable seal across many operating cycles than an unsprung stopcock.
