Büretti kasutatakse analüütilises keemias vedeliku, eriti tiitrimisel oleva reaktiivi täpseks väljastamiseks. Selleks on büretitorul gradueeritud märgid, mille abil saab mõõta vedeliku väljastatud mahtu.
Good to know
Bürett on pikk gradueeritud klaastoru, mille alumises otsas on korkkraan ja korkkraani väljalaskeavas kitsenev kapillaartoru. Vedeliku voolu torust büreti otsa reguleerib korkkraaniklapp.
A burette is used in analytical chemistry for the accurate dispensing of a liquid, especially of one of the reagents in a titration. The burette tube carries graduated marks from which the dispensed volume of the liquid can be determined.
Good to know
A burette is a long, graduated glass tube, with a stopcock at its lower end and a tapered capillary tube at the stopcock's outlet. The flow of liquid from the tube to the burette tip is controlled by the stopcock valve.
