Burets are used to titrate liquids. A buret is filled with a specific volume of a liquid, and placed beneath it is a container such as an Erlenmeyer flask. By opening the valve on the buret, the liquid in the container will then be titrated. High-quality burets have a venting mechanism with which they can be very easily refilled with the exact volume for which the buret is calibrated.
Bureta likidoak neutraltzeko erabiltzen da. Bureta likidozko bolumen jakin batekin betetzen da. Honen azpian Erlenmeyer- en matraze baten moduko ontzi bat jartzen da. Buretaren balbula irekitzean ontziaren likidoa neutralduko da. Kalitate handiko buretek, bureta kalibratu deneko bolumen zehatzarekin berriro betetzea errazten duten deskarga mekanismo bat dute.
