Using water pycnometer allows for the determination of the density of material with open pores and cracks, measured through the water volume. Helium pycnometer uses helium gas to determine the volume of the material, including its internal pores. Based on the known weight of the material, its density can be determined. By comparing and converting the results of these methods, the porosity of the material can be determined.

Water pycnometer:

-Analytical balance Kern ABS-N_ABJ-NM

-YDB-03 kit for density determination

Helium pycnometer:

-Pycnomatic ATC (Thermo scientific Porotec)

-Using helium gas of quality 6 (minimum 4) as the medium. Minimum required weight of the sample is 1 g

y 6 as the medium. Minimum required weight of the sample is 1g.
