A pipette (sometimes spelled pipet) is a laboratory tool commonly used in chemistry, biology and medicine to transport a measured volume of liquid, often as a media dispenser. Burette. Burette, also spelled Buret, laboratory apparatus used in quantitative chemical analysis tomeasure the volume of a liquid or a gas. Oct 12, 2020 · Burets are commonly used when performing titration reactions. A 50 mL class A buret has a tolerance of ±0.05 mL. Like most tools used to make quantitative determinations in the laboratory volumetric glassware can and should be calibrated to improve accuracy. Figure 1: 50 mL Class A buret Calibration is quite simple. The pipette or burette is used to deliver a certain volume of water. The actual volume is determined by measuring the mass of the delivered water and calculating the volume from the known density. There are, however, several factors that must be considered for accurate results. .
