Analytical Chemistry for Technicians by John Kenkel Complete list of books Titration » Burette, pipette, flask - volumetric glassware During titration experiments you will be using several types of volumetric glass. Check out the All Forums page What would you like to say? We will use these numbers - 50mL burette, 0.050mL volume, 0.1% accuracy - throughout the site, when discussing different aspects of titration.

These are too designed to deliver requested amount of solution and they have a scale on the side. In turn that's also about the maximum precision of the titration. The error in judging the reading is therefore bigger that the error from the stop clock.
