How to Read a Burette? A Comprehensive Guide for Accurate Laboratory Measurements


In the precise world of laboratory experiments, mastering the skill of reading a burette accurately is crucial. Burettes are essential tools in volumetric analysis, particularly in titrations, where they measure the volume of a liquid with high precision. This guide provides a systematic approach to burette reading, ensuring accuracy and reliability in your laboratory measurements.

What is a burette?

A burette is a long, cylindrical piece of glassware, marked with a scale, and equipped with a tap at the bottom. It is designed to dispense known volumes of a liquid, especially in titrations. The accurate reading of a burette’s scale is crucial for the success of volumetric analysis.

The Art of Reading the Meniscus

The meniscus is the curved surface of a liquid in the burette. For accurate readings:

Eye Level: Ensure your eye is level with the meniscus to avoid parallax errors.
Center of the Meniscus: For clear liquids, read the bottom of the meniscus. For opaque liquids, align the top of the liquid with the scale mark.

Steps for Accurate Burette Usage

Cleaning: Start with a clean burette to avoid contamination. Rinse it with the solution to be used.

Filling: Fill the burette above the zero mark, ensuring no air bubbles are present.

Initial Volume: Record the starting volume, aligning your eye with the meniscus.

Performing Titration: Carefully dispense the liquid, observing the change in volume.

Final Volume: Note the final volume at the end of the titration, again at eye level with the meniscus.

Volume Calculation: The difference between the initial and final volumes gives the dispensed volume.

Electronic Burettes: A Modern Twist
Electronic burettes offer digital readings, eliminating the need for manual meniscus interpretation and enhancing precision.
