A Pycnometer Of Improved Design, Richard Moore

Journal of the Minnesota Academy of Science

The density of a solution must be known to laboratory medicine , biochemistry, and physical chemistry. Knowledge of the density may permit calculation of solution concentration, solute molecular weight, solute partial, or specific volume , for example. Therefore, the determination of the density of a solution is a measurement which must be made with precision, accuracy, and sensitivity. This report describes a pycnometer which permits making such measurements.
