Weighing in a Filtered Fume Hood?

This white paper shows that accurate weighing results can be attained when choosing the proper combination of a balance within the appropriate ductless filtering fume hood. Weighing requires accuracy, especially when the readability of a balance reaches 0,01mg or more. In many applications the samples being weighed might be harmful or dangerous for the operator to inhale and the use of a filtered fume hood is required for the protection of the laboratory personnel. When using a hood, air flow, drafts, and vibrations can adversely affect the weighing performance of a balance and eventually cause errors to the measurement.
