Paul N. Gardner Company's (Pompano Beach, FL) VF2095 pressure density cup has a fixed internal volume of 100 ml. which is to be compressed by the mechanism of the density cup. After rotation, agitation or dispersion, gas and air can be entrapped within the material.
Under pressure the air will dissolve better into the liquid and any bubbles that are left undissolved will be compressed to a fraction of their original size. Density of the liquid is defined at a very high level of repeatability by weighing. The VF2095 can easily be taken apart to allow easy cleaning.
The Pressure Density Cup takes a fixed volume (100 ml) of the sample and compresses it so that any errors due to entrapped air or gas are eliminated. By weighing the pressurized sample, its true density can be calculated, enhancing the repeatability.
