V-Sorb 2800TP specific surface area and pore size analyzer introduction<br /><br />V-Sorb 2800TP is Gold APP self-developed surface area and porosity analyzer which utilizes static
volumetric. Compared with other companies' analyzers, multi pioneered techs make instrument's performance much better, heighten accuracy and consistence of results, enhance measurement stability,
all these lead to a leading level in domestic competitors and partial applications surpass foreign instruments. Products designed from the user perspective and equipped with fully automated
operation, user-friendly interface makes it easy to learn, imported accessories assure stability and prolong life. Perfect design, sophisticated production and strict testing guarantee to meet
customers' real demands. The high cost performance of V-Sorb 2800TP easily ensure your investment profits and flexible equipped peripheral can satisfy different users' requests.<br
/><br/><h2>Product Feature</h2><br/>V-Sorb 2800TP specific surface area and pore size analyzer features<br /><br />1. Stainless steel micro welding vacuum
manifolds system can reduce the leak rate apparently, improve ultimate vacuum, without daily maintenance and enhance stability.<br />2. Micro welding vacuum system can decrease manifolds'
volume, increases measuring sensitivity and raise accuracy.<br />3. Imported with original packaging molecular pump, ultimate vacuum can reach 5x10-6-0.995, maintenance free, convenient to
use, reduce latter utilization cost.<br />4. Micro welding vacuum system, high vacuum electromagnetically operated valve and high ultimate vacuum molecular pump unite perfectly, bring each
accessories performance into full play, precision degree can reach until 5x10-8.<br />5. Imported high vacuum pneumatic valve's sealing performance is up to 5x10-12 (Pa m3/s), can completely
remove analyzed gas temperature change caused by valve heat.<br />6. Fully metal-to-metal VCR connecting can eliminate O-ring self gas release problem when under high vacuum circumstance,
efficiently improve ultimate vacuum and analysis reliability.<br />7. Imported high-precision silicon thin film capacitive transducer, the core part, can realize auto zero by software; the 1
Torr full-scale (F.S.) transducer assists micropore to achieve a more accuracy data for low P/Po points.<br />8. Modularity design can configure as customer requests, benefits future
functions extension and instrument maintenance.<br />9. Programmable controller electromagnetically operated valve system with high integration and strong anti-interference ability, speed and
easy for upgrade and maintenance.<br />10. Fully auto and modularity design, equipped with dedicated software, can realize unattended operation at night. <br />11. Multi calculating
methods for data reduction provides all-round sample analysis options; powerful data archiving and searching system helps a lot for data management.<br /> Product Specification / Models
V-Sorb 2800TP specific surface area and pore size analyzer parameters<br /><br />Analysis Method: static volumetric nitrogen adsorption<br />Versatility: Adsorption and desorption
isothermal curve analysis, Single and multi point BET method specific surface area analysis, Langmuir method specific surface area analysis, Average particle diameter estimation, T-plot method
external surface area analysis, True density analysis, BJH total pore volume and pore size distribution analysis, T-plot method micropore analysis, MP method micropore analysis, HK method micropore
analysis <br />Vacuum System: V-sorb unique stainless steel micro welding vacuum manifolds system, metal-to-metal (VCR) fittings, reduce dead space in maximum degree and also keep long
duration high vacuum; the VCR metal fittings' vacuum leak rate can reach 1x10-10 (Pa*m3/s), absolutely without usage of any O-ring sealing which will release gas to affect vacuum purity when under
high vacuum condition<br />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<br
/>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<br />Gas Dosing: Can choose He (99.999%) to dose the cold
volume, not only He+Empty cell one type<br />Measuring Ranges: 0.01m2/g to no known upper limit(specific surface area), 0.35 to 2nm (micropore), 2-500nm (mesopore and macropore)<br
/>Accuracy: repeatability errors less than 1.5%<br />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<br />Data Acquisition: high-precision and high integration data acquisition and
archiving system, minimal error, strong anti-interference ability<br />Sample Ports: two samples' analyzing and two samples' degassing concurrently<br />Control System: programmable
controller electromagnetically operated valve system with high integration and strong anti-interference ability, enhance instrument's stability and life<br />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)<br />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%)<br
/>Vacuum Pump: built-in bipolar vacuum pump controlled by patented software which can auto control pump's start/stop<br />Dewar Vessel: imported 4 liter metal made Dewar can provide at
least 72 hours of unattended measurement without refilling the Dewar <br />Partial Pressure: P/Po controllable accuracy range is 5x10-6-0.995<br />Ultimate Vacuum: bipolar pump:
4x10-2Pa (3x10-4Torr), molecular pump: 5x10-6Pa<br />Sample Types: powders, particle, fiber, flakes and other materials<br />Adsorbate Gas: high purity nitrogen (99.999%), Ar, Kr etc.
optional<br />Data Reduction: Windowsu00ae-base independent developed Gold APP softwareTM, perfect versatility, produced full featured and multi-model reports<br
