Fitting a Needle Valve to an Automatic Burette
Automatic burettes, which refill from a reservoir bottle rather than being hand-filled, benefit from a needle valve stopcock that allows the operator to fine-tune dispensing speed during titration without the abrupt on/off action of a simple key stopcock. This variant is dimensioned to fit standard automatic burette assemblies. For a general-purpose needle valve stopcock not specific to automatic burettes, see the PTFE Needle Valve Stopcock.
