Precise Liquid Measurement: A burette is a long, graduated glass or plastic tube designed for accurately dispensing variable volumes of liquid, crucial for titration and quantitative chemical analyses.
Controlled Flow with Stopcock: Equipped with a stopcock at the lower end, allowing precise control over the release of liquids, from dropwise to a steady stream.
Graduated Markings: Features fine graduations, typically in 0.1 mL increments, enabling accurate volume readings by measuring the difference between initial and final readings.
Material Variants: Commonly made from borosilicate glass for chemical resistance and clarity, or plastic (such as polyethylene or PTFE) for durability and shatter resistance.
Essential for Titrations: Widely used in titration experiments to determine the concentration of unknown solutions by delivering a titrant until the reaction reaches its endpoint.
