Description

Volumetric Glassware – Burettes: Precision Tools for Accurate Titration and Fluid Dispensing
Burettes are essential volumetric instruments designed to deliver precise amounts of liquid, primarily used in titration, a core analytical technique in laboratories. These narrow, graduated tubes are equipped with a stopcock at the bottom, allowing controlled release of the liquid.

Their high level of accuracy makes them indispensable in chemical analysis, pharmaceutical testing, quality control, educational labs, and research and development environments.
Manufactured from high-quality borosilicate glass or durable plastic, burettes are resistant to chemicals and thermal shock.

Glass burettes provide superior clarity for accurate reading of meniscus levels, while plastic options offer increased break resistance. Graduations are printed or etched for long-lasting visibility and precision.

Burettes come in several forms, including manual, digital, and self-zeroing burettes, each suited for specific applications. They are available in class A and class B accuracy ratings, with class A being the highest standard used in high-precision work.

Applications of Burettes:

  • Titration Analysis: Used to add titrant precisely to the analyte solution until the reaction reaches its endpoint.
  • Pharmaceutical Testing: Ensures accurate dosing in drug formulation and testing.
  • Food and Beverage Quality Control: Used for acidity/alkalinity testing in products like wine, dairy, and juices.
  • Environmental Testing: Determines water hardness, pollution levels, or chemical composition of samples.
  • Academic Labs: Teaches students precise measurement techniques and titration procedures.
