BELSORP MINI X: BET Specific Surface Area and Pore Size Analyser
Brand: Microtrac MRB | Category: Scientific & Laboratory Equipment
Volumetric gas adsorption analyser for BET specific surface area and pore size distribution, the routine workhorse of the BELSORP range. It measures nitrogen or other gas uptake at cryogenic temperature and derives surface area and pore structure from the isotherm.

More from Laboratory Instruments
- BELSORP MAX X: High-Precision Gas and Vapour Adsorption Analyser
High precision adsorption analyser handling vapours as well as permanent gases, so water, organic solvent and other vapour isotherms can be measured alongside nitrogen. It is the research grade instrument in the BELSORP line, used for micropore analysis and adsorbent development.
- TURBISCAN DNS: Dispersibility and Stability Analyser
Analyser that measures how readily a powder disperses into a liquid as well as how stable the resulting dispersion is, by scanning the vessel while dispersion takes place. Dispersibility and stability are separate properties, and this instrument records both in the same run.
- BELSORP MAX G: High-Precision Gas Adsorption Analyser
High precision gas adsorption analyser for surface area and pore size distribution, configured for permanent gases rather than vapours. It sits between the MINI X and the MAX X, giving research grade precision for laboratories that do not need vapour capability.
