A laboratory burette with a stopcock is used for highly precise dispensing of liquid volumes, primarily in titrations to determine unknown concentrations by adding a known solution (titrant) drop-by-drop or in a controlled stream into another solution (analyte). The stopcock, a valve at the bottom, offers controlled flow, while the graduated scale allows accurate reading of dispensed volumes, crucial for analytical chemistry, pharmacy, and educational experiments.
