When is burette calibration required?

To maintain the quality of the titration results, the burette must be in good condition and properly calibrated. It is recommended to calibrate the burette every 6-12 months depending on the following factors:

1. Frequency of burette use
2. Type of liquid dispensed by the burette
3. Long period of non-usage
4. Handling and care of burette
5. Titration applications that require superior accuracy also demand more frequent calibration

Establishing an appropriate calibration frequency minimizes the possibility of incorrect liquid delivery in the laboratory and ensures traceability, accountability and confidence in the results.
