LXIV. On the drop-weight method for determining surface-tensions

The Falling Drop Method for Determining Specific

Recognizing the increasing importance attached to water exchange in the body for the study of many clinical and physiological conditions we (1) described in 1924 a new and convenient method of determining specific gravity. Obvious advantages attach to densimetry performed with 1 drop of body fluid, in less than a minute’s time. While these ends were attained by the method as first described it ...

Rheological Method for Determining Molecular Weight and Molecular Weight Distribution

On the Surface Tensions of Binary Mixtures

For binary mixtures with fixed concentrations of the species, various relationships between the surface tensions and the concentrations are briefly reviewed.

A simple titration method for determining the specific gravity on one drop of urine.

Samples of urine which have been collected by ureteric catheterization are necessarily small in volume, often only a few drops. In order to determine the efficiency of kidney function it may be necessary to measure the specific gravity of these small samples, but it is impossible to use the hydrometer method, which requires a minimum of about 50 ml. of urine. Methods involving the suspension of...
