Analytical balances weigh dry substances {weighing, analysis}|. First, find weighing-paper, weighing-bottle, or weighing-dish tare weight. Find sample and container weight. Subtract tare weight to find sample weight. Weighing is at constant temperature, usually 24 C. No finger oil and no air drafts can affect sample. Analytical balances are not for sodium hydroxide, hydrogen iodide, hydrogen bromide, iodine, or bromine, which are corrosive.
