Description

Precision quartz pyknometer, accession no.71; circa 1970s

Precision quartz pyknometer designed by Dr. Theodore Shedlovsky for determining the specific gravity of a solution by weighing a known volume. The usual apparatus resembles a flask with a glass stopper. In this novel version made of quarts in U-shape, precision quartz capillary tubes are fused to its ends. Calibration of the contained column has been made for various temperatures, as seen through the magnifying glass.
