When to use a pipette and burette


They both have gradations to measure the quantity of chemical substances. While burette is used to deliver a chemical solution with a known concentration into a flask, pipette is used to measure the quantity of the analyte- the chemical substrate whose concentration is to be determined.

When should a burette be used?

Burette is commonly used in the titration process for quantitative analysis in many industrial chemical testing where a solution of known concentration is used to find the concentration of an unknown solution.

What is the difference between a pipette and a dropper burette?

(1) Release mechanism : Burettes have a stopcock at the bottom whereas a pipette has a dropper like system that releases liquid in the desired amount by lessening the vacuum. (2) A pipette is smaller than burette. (3) Pipettes are more accurate in releasing liquid in smaller quantities than burettes in a .

Why are pipettes and burettes used?

Volumetric pipette had more accuracy as compared to buret and mechanical pipette. Also, as the sample size increased accuracy also increased for volumetric pipette and buret, but there was no large change in the accuracy of mechanical pipette.
