Gas pycnometer - Wikipedia
A gas pycnometer is a laboratory device used for measuring the density —or, more accurately, the volume —of solids, be they regularly shaped, porous or non-porous, monolithic, powdered, granular or in some way comminuted, employing some method of gas displacement and the volume:pressure relationship known as Boyle's Law.

Pycnometers are used for measuring and comparing densities or specific gravities of liquids and solids, including soil. What Is a Pycnometer? Pycnometer bottles are usually made of glass and have a ground glass stopper with a capillary tube for air bubbles to escape.
Pycnometer - Chemical Engineering - University of Utah
The pycnometer (from the Greek puknos, meaning “density”, also called pyknometer or specific gravity bottle), is a flask with a close-fitting ground glass stopper with a fine hole through it, so that a given volume can be accurately obtained (Figure 1).
Pycnometer - an overview | ScienceDirect Topics
A pycnometer allows measuring the volume and the density of solid objects in a non-destructive manner. The latter is accomplished by employing Archimedes’ principle of fluid displacement and Boyle’s law of volume-pressure relationships, respectively, for liquid and gas pycnometers ( Tamari and Aguilar-Chavez, 2005 ).
