Surface Area and Pore Size Analyzer

Redefining “Fully Automatic”: Switching between Degassing and Testing Fully Automatic
Redefining “high throughput”:12 analysis bits,mesoporous + micropore
Eliminate helium pollution:helium gas test dead volume → vacuum heating degassing → adsorption test

Main Function

• High throughput rapid specific surface area analysis
  Pore volume and pore size distribution (mesopores, micropores, ultra micropores)
  Conventional gas adsorption, such as N2, O2, Ar, CO, CO2, etc
  Adsorption of flammable gases, such as H2, CH4, C2H6 and other alkylene alkynes


• 12 samples were analyzed simultaneously


• BET multi-point method test results


• Isotherm(P/P0<E-9)


• Gas adsorption isotherm diagram

Technical Advantages

1. High throughput and efficiency: Support analysis of 3/6/9/12 samples at a time


2. Truly fully automated: the world's first degassing furnace and dewar cup automatically switch, no manual transfer of sample tube or degassing furnace
   Completely eliminate helium pollution:helium gas test dead volume → vacuum heating degassing → adsorption test,taking the lead in solving the problem of helium contamination in microporous analysis internationally and improving testing accuracy


3. High time utilization rate: solves the time waste of conventional instruments being degassed after work and unable to start testing, making it a reality to install samples after work and read data at work;


4. Program controlled pressure degassing: supports "program controlled pressure" and "program controlled temperature" degassing, automatically lifting and lowering the degassing furnace according to pressure changes to prevent sample flying;


5. Full constant temperature of the gas circuit system: The internal gas circuit system of the instrument is fully constant temperature to 40 ℃, with an accuracy better than 0.1 ℃;


6. Sample tube sealing: The one-time sealing technology for 6 sample tubes in a single analysis station eliminates the need for individual tube sealing, providing an ultimate efficiency experience;


7. Multiple intake: optional with 8 independent intake channels; It can support the adsorption of CO2, O2, Ar, CO, H2, CH4, C2H6 alkynes and other gases;


8. Upward moving door: user-friendly and easy to open and close, saving laboratory space;


9. Electric turbine liquid nitrogen pump: humanized liquid nitrogen addition, stepless speed regulation, random movement, safety and convenience, and no pollution of liquid nitrogen;


10. Scale communication: Connect the scale, voice broadcast the weight and automatically input it;


11. High reliability: an international supplier system, with core components imported with original packaging;
