Brand: Microtrac MRB | Category: Scientific & Laboratory Equipment
Mercury intrusion porosimeter that forces mercury into a porous solid under increasing pressure to derive pore size distribution and total pore volume. It covers the macropore and mesopore range that gas adsorption cannot reach, and is used on ceramics, catalysts, cements and rock.

Gas pycnometer that determines true density of powders and porous solids by measuring the volume of gas that the sample displaces, so open pores are excluded from the volume. Helium is normally used because its small molecule penetrates fine pore structures.
High pressure adsorption instrument for measuring gas uptake well above atmospheric pressure. That is the regime that matters for hydrogen and methane storage, for carbon dioxide capture and for screening adsorbents used in gas separation. Isotherms are measured volumetrically, as on the other BELSORP instruments, but with a pressure range that ordinary surface area analysers do not reach.
Larger chamber version of the BELPYCNO gas pycnometer, for samples too bulky for the standard cell. It uses the same gas displacement principle to give true density excluding open porosity.
