Applications

Liquid-liquid extractions, organic phase washes, separations in organic chemical synthesis and quality control. The conical body aids visualisation of the phase interface and allows complete drainage with no residue on the walls.

Usage Notes

The ground glass stopcock resists most organic solvents without degradation — an advantage over PTFE stopcocks when working with certain halogenated solvents. For highly aggressive solvents or pressurised applications, verify chemical compatibility before use.
