Certificate of Calibration for Serialized Class A Glass

Accurate, reliable scientific work relies on precision in measurement wherever it is applied. This includes equipment like balances and scales but also manual tools like graduated cylinders or burettes. Volumetric glassware calibration helps ensure the measuring accuracy of laboratory glass pieces wherever they are used prior to being sold. There are also recommendations available for the recalibration of older pieces to ensure they are still measuring accurately after a certain period of time, based on the type of glass.

Below you will find an example of a certificate created for a calibrated piece of serialized Class A glassware manufactured by Glassco. This type of certificate describes the calibrated piece of glass, the test method, the item batch, and the testing results.
