Porosimetry

Pure density, Porosimetry, Permeability

Buoyancy weighing (Archimedes’ principle) with isopropanol
Determination of pure density, bulk density as well as open porosity of solid rock samples

Mercury porosimeter
Analysis of pore throat diameter distribution and porosity
Large measuring range from 950 μm to 3 nm pore diameter
High sample throughput due to the presence of two low-pressure and one high-pressure station
Possibility to measure different sample geometries (cylindrical samples or single fragments) by using different sample cells

Permeability measurements
Determination of air permeability by means of Hassler cell at different pressure levels
Transportable air permeameter Tiny Perm II for permeability measurements under laboratory conditions and in the field
