Measuring Ranges: 0.01m²/g to no known upper limit (surface area)

0.35 to 400nm (pore size)

Accuracy: repeatability errors ≤1%

Vacuum System: V-Sorb unique monolithic manifolds and solenoid valve control system, greatly reduce the dead volume; improve the adsorbate micro-change sensitivity; enhance pore size distribution analysis resolution; decrease connecting points; strengthen sealing performance and prolonged instrument life

Coolant Level Prober: V-Sorb original coolant level control system with temperature probe, ensure the coolant level unchanged when compares with sample cells in the whole analysis process, completely eliminate the analysis errors caused by dead volume change

Sample Treatment: the whole treatment procedures are controlled by dedicated software, as well with a start time preset function which can realize unattended operation at night

Control System: programmable solenoid valve system with high integration and strong anti-interference ability, enhance instrument’s stability and life

Sample Ports: two samples’ analyzing and two samples’ degassing concurrently

Pressure Measurement: imported sectional measuring dual pressure transducer, notably improve the measuring accuracy at low P/P_o point, 0-1000Torr (0-133Kpa), 0-10Torr (0-1.33Kpa)

Transducer Accuracy: imported silicon thin film transducer, accuracy can reach 0.1% of real reading, better than 0.1% of F.S.(full-scale), far accurate than Pirani resistance vacuum gauge(general error is 10%-15%)

Partial Pressure: P/P_o controllable accuracy range is 5x10^-6-0.995

Ultimate Vacuum: 4x10^-2Pa (3x10^-4Torr)

Vacuum Pump: built-in bipolar vacuum pump controlled by patented software which can auto control pump’s start/stop

Sample Types: powders, particle, fiber, flakes and other materials

Adsorbate Gas: high purity nitrogen (≥99.999%), Ar, Kr, CO, CO2 etc. non-corrosive gases area optional

Data Acquisition: high-precision and high integration data acquisition modules, minimal errors, strong anti-interference ability

Data Reduction: Windows®-based independent developed Gold APP software^TM, perfect versatility, produced full featured and multi-model reports
