V-Sorb 2800 Surface Area and Mesopore Analyzer Introduction

V-Sorb 2800 surface area and mesopore analyzer is researched by Gold APP Instruments for surface area and mesopore size testing by 

utilizing static volumetric principle. Equipment designed from the user perspective and with fully automated operation system, user-friendly 

interface makes it easy to learn, branded accessories assure stability and prolong working life. 

V-Sorb 2800 Surface Area and Mesopore Analyzer Specifications

1. Analysis Principle: volumetric adsorption principle

2. Testing Abilities: Adsorption/ desorption isotherms, single & multi-point BET (Brunauer-Emmett-Teller) surface area, Langmuir surface area, 

external surface area, BJH (Barrett-Joyner-Halenda) total pore volume and pore size distribution

3. Measuring Ranges: 0.01 m²/g (by nitrogen)/ 0.0005m²/g (by krypton) to no known upper limit (specific surface area); 2 to 500nm (pore size)

4. Accuracy: repeatability errors within 1%

5. Coolant Level Prober: V-Sorb original coolant level probe system with temperature probe, ensure the coolant level unchanged when compares with sample cells in the whole analysis process

V-Sorb 2800 Surface Area and Mesopore Analyzer Technical Features

1. Unique integral manifolds system, decrease connecting points apparently, reduce leak rate, improve ultimate vacuum.

2. Modularity design can configure as customer requests, benefits future functions extension and instrument maintenance.

3. Programmable solenoid valve system, strong anti-interference ability, convenient for installation and uninstallation.

4. Separated analysis and pretreatment manifolds can avoid foreign matter to contaminate manifolds during sample pretreatment.

5. Pioneered gas outlet and inlet control system can efficiently prevent sample splash in vacuuming and gas input process, guarantee clean 

manifolds and sample weight unchanged, avoid zero and liner drifting caused by transducer macro-change.

6. High precision and integration data acquisition module is easy to connect, minimal errors and strong anti-interference ability; standard 485 

communication mode is good for analyzer applications extension and interconnection, can also conveniently switched to RS232 & USB modes.

7. Multi calculating methods for data reduction provides all-round sample analysis options; powerful data archiving and searching system helps a lot for data management.
