Fitting a Needle Valve to a Standard Burette
This needle valve is sized for standard, hand-filled burettes rather than the automatic-refill type, giving titration users fine control over dispensing speed without abrupt on/off action. The PTFE needle resists attack from acids, alkalis, and most laboratory solvents, and requires no lubricating grease. For a version dimensioned specifically for automatic burettes, see the PTFE Needle Valve Stopcock, Automatic Burette.
