3P micro 200

The 3P micro 200 is a fully automated volumetric sorption analyzer for measuring adsorption and desorption of Nitrogen and other non-corrosive gases on two independent analysis stations. The instrument can be fitted with a turbomolecular pump and low-pressure sensors for micropore analysis and Krypton physisorption. Depending on customer requests, the instrument can be equipped with two mesopore stations (A version), one micro- and one mesopore station (B1 and B version) or two micropore stations (C1 and C version). Each analysis station has its own dosing manifold for optimal analysis duration. Regardless of the starting time, the analysis will take the same amount of time! Each analysis station comes with its own p0-cell with a dedicated pressure sensor. The stations are fully independent from one another, analysis can be started at any given time. Two separate degassing stations are integrated into the 3P micro 200 and can be operated parallel with the analysis stations.
