Quick Answer: A Glass Key Stopcock For Burette is a ground-glass valve fitted into a burette to control the flow of titrant during titration and other liquid-dispensing laboratory work. Its ground-glass key seals against the stopcock barrel by precision fit and typically needs a thin film of stopcock grease to turn smoothly and seal reliably, offering excellent chemical resistance for a wide range of reagents.

Maintaining a Glass Key Stopcock

A ground-glass key stopcock delivers excellent chemical resistance and a precision seal, but unlike a PTFE-key stopcock it typically needs a thin film of stopcock grease applied periodically to turn smoothly and prevent the key from seizing if left dry or unused for extended periods. Buyers running frequent titrations with aggressive reagents, or who prefer a grease-free valve, may instead consider Lab Glassware Manufacturer's PTFE Key Stopcock Burette, which is self-lubricating.
