RESEARCH IN SELF-DIFFUSION IN LIQUIDS. THE MANUFACTURE OF MAGNETIC MICROFLOATS FOR DENSITY MEASUREMENTS

Abstract

IN CONNECTION WITH DIFFUSION MEASUREMENTS IN LIQUIDS USING HEAVY ISOTOPES AS TRACERS, A MAGNETIC FLOAT METHOD FOR MEASURING LIQUID DENSITIES IN VERY SMALL SAMPLES WAS DEVELOPED. A detailed description of the methods used to make the magnetic microfloats for density measurements in liquid volumes down to 0.03 ml is given; the volume of the float is about 0.020 ml. Although the floats were made to match cyclohexane at 25 C, density 0.775 g/cc, no particular difficulty was encountered in matching the float to, for instance n-hexane (0.657 g/cc at 25 C).
