Microtrac MRB | Surface Area and Pore Size

The BELSORP HP analyzer is used for high-pressure adsorption measurement.

The importance of high-pressure adsorption measurement is growing in various application fields like hydrogen or methane storage, pressure swing adsorption (PSA), CO2 absorption into hypolymer, and many more. However, the instruments for measuring high-pressure gas sorption are usually large-sized, expensive and difficult to use.

The BELSORP HP is a benchtop instrument for high-pressure adsorption measurement. It is compact, reasonably priced and easy to operate. Our profound expertise in adsorption science is reflected in the technology implemented in this analyzer. The BELSORP HP is used in research and industrial applications alike.

NOTE: PC, R.P. and chiller are required to operate this product. Please contact us for more information.
