Vacuum Cavity: V-sorb unique assembling-installed manifolds and electromagnetically operated 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
Measurement Modes: “N2” and standard “N2+He” modes are available. The “N2+He” mode accords with international criterion, can guarantee the accuracy and consistence; it is not suitable to employs He to measure free space due to some samples can adsorb He in low temperature, but, ideal analysis results can get by using “N2” mode
Gas Dosing: Can choose He (99.999%) to dose the cold volume, not only “He+Empty cell” one type
Measuring Ranges: 0.01㎡/g to no known upper limit(specific surface area), 0.35 to 2nm (micropore), 2-500nm (mesopore and macropore)
Accuracy: repeatability errors ≤1.5%
Coolant Level Controller: V-sorb original coolant level control system, 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
Data Acquisition: high-precision and high integration data acquisition and archiving system, minimal error, strong anti-interference ability
Sample Ports: two samples’ analyzing and two samples’ degassing concurrently
Control System: programmable controller electromagnetically operated valve system with high integration and strong anti-interference ability, enhance instrument’s stability and life
Pressure Measurement: imported sectional measuring dual pressure transducer, notably improve the measuring accuracy at low P/Po point, 0-1000Torr (0-133Kpa), 0-10Torr (0-1.33Kpa)
Transducer Accuracy: imported silicon thin film pressure transducer, accuracy can reach 0.15% of real reading, better than 0.15% of F.S.(full-scale), far accurate than Pirani resistance vacuum gauge(general error is 10%-15%)
Vacuum Pump: built-in bipolar vacuum pump controlled by patented software which can auto control pump’s start/stop
Dewar Vessel: imported 4 liter metal made Dewar can provide at least 72 hours of unattended measurement without refilling the Dewar
Partial Pressure: P/Po controllable accuracy range is 5x10-6-0.995
Ultimate Vacuum: bipolar pump: 4x10-2Pa (3x10-4Torr), molecular pump: 5x10-6Pa
Sample Types: powders, particle, fiber, flakes and other materials
Adsorbate Gas: high purity nitrogen(≥99.999%), Ar, Kr etc. optional
Data Reduction: Windows®-base independent developed Gold APP softwareTM, perfect versatility, produced full featured and multi-model reports

Carbon Black / White Carbon Black
Tire and rubber manufacturers find that the specific surface area of carbon black has great influences on the service life, friction and rubber performance. The carbon black or white carbon black with proper specific surface area can be selected according to the tire or rubber purposes.
Nanometer Materials
Surface area and porosity of nanometer materials are decisive for their hydrogen storage, oxygen storage and special substance adsorption, such as the typical CNT (carbon nano tube).
Electric Field
The inner filling materials of capacitor require high specific surface, so as to produce capacitor with smaller volume but larger capacity. Likewise, in the design of ordinary batteries, it is also necessary to consider the material's specific surface area, so as to gain smaller volume and larger storage power.
New Energy Battery
New energy battery is the hot field for research currently. It controls the proper stored energy density by controlling the material's specific surface.
Paints and Coatings
Filler surface area of paints and coatings affects the smoothness, texture, color, color saturation, brightness, solid content and film's adhesion property. The porosity can control the application program's performance, such as liquidity, curing time and coating thickness, etc.
Catalyst's active specific surface area and pore structure have great influence on the conversion ratio. Choose the aperture size to filter or transit some substance selectively, so as to create a selective catalyst, and in turn, produce the desired products.
Automobile Exhaust  
Purification of resultants of the automobile exhaust requires special catalyst material. The exhaust purification using transition metal is of important practical significance and economic value. The specific surface and porosity decide the efficiency, service life and economical efficiency of the exhaust conversion device.
Combustion Control
In the research and development of rocket propellant and explosive, it is necessary to control the combustion rate by controlling the material's specific surface. If the speed is too high, it may be more dangerous; while if the speed is too low, it may cause failure and inaccuracy.
Active Carbon
Besides serving as an extremely great carrier material, the active carbon is also an ideal filtering material. The filtering effects can be controlled by controlling the active carbon's specific surface and porosity. It has important application in the gas and liquid purification fields.
The tablet dissolution rate and medical effect action time can be controlled by rationally distributing the effective constituents of the medicines on the filler with certain specific surface area and porosity.
Currently, dealers, distributors, agents, wholesalers are recruiting. If you interest or deem your country has a big and unexplored market, pls. let us know. Thanks!
