CIQTEK EASY-V 3220 and 3210 are BET specific surface area and pore size analyzers independently developed by CIQTEK using the static volumetric method.
- Specific surface area testing, range 0.0005 (m2/g) and above.
- Pore size analysis: 0.35-2 nm (micropore), micropore size distribution analysis; 2-500 nm (mesopore or macropore).
- Two analysis stations. EASY-V 3220: 2 samples can be tested simultaneously; EASY-V 3210: 2 samples can be tested alternately.
- Equipped with a molecular pump.
- Built-in test computer, safe and stable. 10-inch capacitive touch screen, tablet control supported.
- 2 sampling ports and 1 P0 tubing port for each test module. The Po tube can be used for specific surface area testing economically.
- The protective protective door can prevent accidents caused by accidental contact with low-temperature liquid nitrogen and eliminate the influence of environmental factors on the test.
- Two independent sample processing ports can be performed simultaneously with sample testing to improve testing efficiency.
- The 4L stainless steel inner Dewar bottle overcomes the fragile defects of glass Dewar bottle, and the high thermal insulation ensures continuous testing for more than 72 hours.
- The built-in ball screw lifting system driven by stepper motor eliminates the shortcomings of ordinary screw types that are easy to jam, etc.
Technical specifications:
Test function:
Static volume principle, adsorption/desorption isotherm measurement, single and multi-point BET method, Langmuir method, t-graph external surface area measurement; BJH total pore volume and pore size distribution analysis, true density measurement, DR and DA filling theory, HK micropore analysis, SF micropore analysis, MP micropore analysis, t-graph micropore analysis; Powerful online data analysis system, as well as specific surface area and pore size distribution testing system to ensure more stable and accurate testing data.
Test ranges:
0.0005 (m2/g)～unknown upper limit (specific surface area);
0.35nm-500nm, 0.0001cm3/g-unknown upper limit (total pore volume).
Test accuracy:
Specific surface area repeatability error ≤ ±1.0%, pore size repeatability most probable deviation ≤ 0.02nm.
Sample No.:
EASY-V 3220: dual sample testing;
EASY-V 3210: Alternating dual sample testing.
Dual sample degassing processing, sample testing system and sample processing system are independent; Sample testing and processing can be performed simultaneously, which can avoid contamination of the testing pipeline, further ensuring the test accuracy and prolonging the service life of the instrument.
Testing modes:
Integrated "Single Nitrogen Testing Mode" and "Nitrogen + Helium Standard Testing Mode" for customers to choose according to their actual needs;
"Nitrogen + Helium Standard Testing Mode", which complies with international standards, can ensure the accuracy and consistency of the results, and is easy to operate;
For samples that can adsorb helium at low temperatures, helium gas is not suitable for determining the headspace. "Single Nitrogen Testing Mode" can obtain the desired test results.
