A gas pycnometer is also sometimes referred to as a helium pycnometer. The instrument invented by al-Bīrūnī, which functions on the principle of water volume displacement, is essentially the …

The density measured by Helium Pycnometry is often referred to as “helium density” implying that open pores excluded in the calculation. Since He cannot access closed pores, they are …

The AccuPyc gas pycnometer from Micromeritics is trusted around the world to provide the most reliable determinations of true density. More labs choose an AccuPyc than any other …

Measure density of solids and semi-solids in under 10 minutes with built-in temperature control and contamination prevention across models.

Gas (helium) pycnometer is a laboratory or field instrument that measures volume (density) of materials using gas displacement method by employing the ideal gas law, pV = nRT.

The gas pycnometer replaces the classical method of liquid displacement, utilizing a probing gas such as Helium which can reach even the smallest pores with less than one nanometer in …

The MicroMeritics AccuPyc II Pycnometer is an easy to use, fully automatic gas displacement pycnometer. It determines density and volume by measuring the pressure change of helium …

Jul 17, 2025 · The Micrometrics Gas Pycnometer uses high purity helium gas to determine the true volume of a sample. The sample is stored in in an air tight container, which is filled with …

Gas pycnometry, also known as helium or He pycnometry, can be used to measure the volume and calculate the density of powders and other solid materials.
