Brand: Microtrac MRB | Category: Scientific & Laboratory Equipment
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.

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.
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.
Vacuum degassing station that removes adsorbed moisture and gases from samples before an adsorption measurement. Incomplete degassing is the commonest source of error in BET surface area work, because residual water occupies the sites the measurement is meant to count.
