To read a burette properly, find the meniscus, which is the liquid's curved surface, and read the bottom of the meniscus at eye level. Make sure you are reading the scale from top to bottom in ascending order and that the burette marks are visible.
According to chemscience.com, a burette is a piece of glassware used in laboratories to measure and dispense exact, variable amounts of liquid, usually in analytical chemistry. By introducing a solution with a known concentration, it is mostly utilised in titration to ascertain the concentration of an unknown solution.
The accuracy of a burette is usually within ±0.05 mL per reading. A burette can therefore measure volumes to within ±0.05 mL of the actual quantity.
A 50 mL laboratory glass tube is commonly used as a burette to deliver an accurate, measured volume of liquid. Gradients, often in increments of 0.1 mL, are used to indicate the volume of liquid that it can retain. Burettes are available in quantities such as 25 mL and 10 mL, but the most popular size is 50 mL.
