Why burets are accurate?

Burets are accurate because they provide precise control over the volume of liquid dispensed, allowing for small, incremental changes in volume. Their design includes a stopcock that enables fine adjustments, which is crucial for titrations and other analytical procedures. Additionally, the uniform diameter of the buret ensures consistent fluid flow and minimizes the risk of air bubbles, enhancing measurement reliability. This level of precision makes burets essential tools in laboratory settings for quantitative analyses.
