                Sources of Systematic Error

   A. Instrument Error

    All measuring devices are sources of determinate errors, such as
        uncalibrated pipets, burets, and volumetric flasks.

    Electronic instruments such as spectrometers.
     Minimise instrument errors by frequent calibration both for apparatus such
        as volumetric flasks, burettes etc., but also for electronic devices such as
        spectrometers.
