View your post here. Mendham and others Complete list of books Titration » Burette, pipette, flask - volumetric glassware During titration experiments you will be using several types of volumetric glass. 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.
