True Density Gas Pycnometer for Powders

Helium pycnometer determining true or skeletal density of powders and porous solids. Used in ceramic, pharma, battery and mineral labs. Helium fills open pores, so the result reflects the real solid density of the sample.

Specification

A weighed sample in a calibrated cell is subjected to helium at fixed pressure and expanded to a reference chamber. Pressure change gives volume by gas law and density with repeatability of 0.03 percent.

Features

• Helium gas displacement
• Cell sizes 10, 35, 100 cc
• Automatic purge and run
• Temperature compensated
• Results with standard deviation
