What is Buret?
A buret (or burette) is a graduated glass tube with a stopcock at the bottom, used in titrations to deliver a precise, variable volume of liquid solution. Burets are commonly calibrated to 0.1 mL, with readings estimated to 0.01 mL. They are essential for acid-base, redox, precipitation, and complexometric titrations in analytical chemistry.

A buret (or burette) is a graduated glass tube with a stopcock at the bottom, used in titrations to deliver a precise, variable volume of liquid solution. Burets are commonly calibrated to 0.1 mL, with readings estimated to 0.01 mL. They are essential for acid-base, redox, precipitation, and complexometric titrations in analytical chemistry.
Burets are used in acid-base titrations, redox titrations, complexometric titrations, and precipitation titrations. Microburets (≤10 mL) are used in non-aqueous potentiometric titrations and when analyte quantities are limited.
Burets are fragile glass instruments. Handle carefully to avoid breakage (laceration hazard). When filling or draining, ensure the solution is compatible with the stopcock material. If a corrosive or toxic titrant is used (e.g., KMnO₄, NaOH), wear gloves and eye protection.
