Pressure Density Cups or Pycnometers/Pyknometers are designed to measure the liquid sample density with minimum error. Some paints tend to pick up significant quantities of air during manufacture. This instrument operates on the principle of compressing the paint to such an extent that included air bubbles are reduced to a negligible volume.
