Metrology BET Surface Area

Microtrac BELSORP MAX X Surface and Pore Analyzer

A high-precision gas and vapor adsorption system for BET surface area and pore size distribution. It supports multi-sample analysis, micropore characterization, and vapor sorption studies.

BELSORP MAX X
Sample Capacity Up to 4 samples
AFSM Technology High-accuracy free space
High Pressure Model Up to 1 MPa
Reproducibility 0.4 to 1.2 percent

System Capabilities

The BELSORP MAX X measures adsorption isotherms for surface area and pore size distribution across micro to macro pores. It supports vapor sorption for hydrophilicity and hydrophobicity studies.

AFSM technology compensates for free space changes, improving accuracy for low surface area samples and advanced R and D work.
