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

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.
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.
The current generation vacuum degasser in the BELPREP line, preparing samples for gas adsorption analysis by heating them under vacuum until adsorbed species are removed. It is used ahead of BET surface area and pore size measurements.
