BELSORP-miniⅡ

Automatic specific surface area/
pore size distribution measurment

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.
