Physical Influences and Calibration
Analytical balance readouts can be affected by changes in the sample and/or container as well as other physical influences.
Use clean and dry containers for samples, and avoid beakers with large or wide openings. Pick the smallest container possible, and cover it if needed.
Condition the sample/container to the prevailing temperature, to avoid issues with repeatability and weighing results. You may also find drifts in the readout value (even with a stable display when the balance isn’t loaded) otherwise.
Evaporation may occur in uncovered samples/containers, or they may absorb water if handled with bare fingers. Readouts could increase or decrease continuously, or you may find drift (even with a stable display when the balance isn’t loaded).
