| + | 59 | '''Displacement.''' Adding 2 mL of diluent to a vial containing 5 mg of solid produces slightly more than 2 mL of solution, because the dissolved solid occupies volume. For peptide masses of a few milligrams in a millilitre or more of diluent the effect is on the order of a few thousandths of a millilitre and is negligible against the graduation interval of the syringe. It ceases to be negligible when the solid mass approaches the diluent volume, which does not arise in the cases this tool is used for. | |
