BELSORP-miniII is a compact, volumetric adsorption measurement instrument used for specific surface area and pore distribution measurement. Up to 3 samples can be measured simultaneously and independently with dedicated software, which makes operation of the instrument straightforward.
Overview
BELSORP-miniII uses a new method for free space measurement (AFSM), which enables high accuracy and reproducible data analysis to be performed. BELSORP-miniII can be widely used for both research and QC in industry and academia.
