V-Sorb 4800 BET Surface Area and Pore Volume Analyzer Introduction

V-Sorb 4800 BET surface area and pore volume analyzer is researched by Gold APP Instruments for surface area and pore size testing by utilizing static volumetric principle. It can be used for those materials which pore size is limited to mesopore (2-50nm), of course plus the surface area data determination too. High cost performance and high through-put of V-Sorb 4800 BET surface area and pore volume analyzer easily meet your demands no matter in research or quality control.

V-Sorb 4800 BET Surface Area and Pore Volume Analyzer Specifications

1. Analysis Principle: volumetric nitrogen adsorption.

2. Analysis Data: adsorption/ desorption isotherms, BET (Brunauer-Emmett-Teller) surface area, Langmuir surface area, t-plot surface area, BJH (Barrett-Joyner-Halenda) pore size distribution, pore volume analysis.

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 ≤1%.

5. Coolant Level Prober: V-Sorb original coolant level probe system with temperature probe.

6. Sample Degassing: the whole degassing be controlled by software, as well with a start time preset function which can realize unattended operation at night.

7. Sample Stations: 4 testing and 4 degassing concurrently.

8. Pressure Transducer: imported silicon thin film pressure transducer, accuracy can reach 0.1% of real reading, better than 0.1% of F.S.(full-scale). P/Po controllable accuracy range is 5x10^-6－0.998
