The Multipycnometer is the most versatile manual pycnometer. It gains its name from its multiple volume feature that offers three sizes of interchangeable sample cells: 135 cc, 20 cc, and 4.5 cc. In addition, there are three different calibrated reference volumes which provide peak performance for each cell size. The operating sequence is reversed from that of the
Stereopycnometer... pressurizing the reference volume first, then expanding the gas into
the sample cell.
