Quick Answer: A Glass Straight Stopcock is a standalone ground-glass valve with a simple open-or-closed bore, supplied separately from a burette for use as a replacement part or for fitting into custom glassware assemblies. Its ground-glass key offers excellent chemical resistance and a precision seal, typically maintained with a thin film of stopcock grease.

Using a Standalone Straight Stopcock
Because this stopcock is supplied as a standalone part rather than pre-fitted to a burette, it is commonly used to replace a worn or damaged stopcock on an existing burette, or fitted into custom laboratory glassware assemblies that call for a simple open-or-closed valve rather than fine needle-valve control. For applications needing precise, dropwise flow control instead, Lab Glassware Manufacturer also supplies the PTFE Needle Valve Stopcock Straight.
