    b All Open Pores include all pores accessible to external fluids (i.e., including blind pores closed at one end).
    c Substantially shorter in multi-station instruments capable of analyzing multiple samples simultaneously.
    d For standard BET analyses with N2 or Kr at 77 K, argon at 87 K, etc. (not needed for, e.g., CO2 analyses at 273 K).
    e Optionally used for cold trap only.

    Gas Sorption

    Autosorb iQ Series

    The Autosorb iQ series represents the gold standard in high resolution/high sensitivity gas sorption. Metal-to-metal (VCR) fittings are employed in the measurement manifold(s) for extremely low leak rates. Available with up to three physisorption analysis ports for surface area analysis and pore size measurements; any or all can be equipped for low pressure micropore analysis including 0.1 torr transducer(s). All models (except one chemisorption-only model) include four built-in degas ports which eliminates the need to degas on the analysis stations thus preventing contamination of the analysis section. One port is available as a chemisorption station, complete with a high temperature furnace coupled with fan-assisted cooling. The chemi- versions are also offered with optional flow-based measurement capabilities (TPX, pulse titration). A number of options are available, including an enclosed and fully thermostatted vapor generator and dosing system. A single PC is able to control up to 4 autosorb iQ units, and the software features the most advanced pore size calculations.

    Quadrasorb-evo

    Up to four simultaneous and independent analysis ports remove the limitations of single dewar systems allowing samples to be started as soon as previous measurements are completed. Krypton / Micropore option available for low surface area and micropore measurements. External roughing pump supplied separately. Secure PC version (21 CFR Part II) is also available. more...

    Mercury Porosimetry

    PoreMaster Series

    Automatic pore size distribution and pore volume analyzers using the rapid mercury intrusion method. Pore size range measured from approximately 1100* µm diameter to less than 3.5nm in the 60,000 psi capable units, 6.5nm in the 33,000 psi models. Both versions have two, built-in low pressure analysis ports for pore sizes above 4 µm. The high pressure cavity, for pore sizes smaller than 4 µm accommodates one sample cell in the standard unit, and two cells in the GT model for greater throughput. PoreMasters can also be used to determine the crush strength of hollow glass microspheres and for water intrusion studies on hydrophobic materials. more...

    Capillary Flow Porometry

    Porometer Series (Liquid Expulsion)

    Our capillary flow porometers for characerizing through-pores in thin, sheet-like materials provide exceptional performance in compact desk top units. They are ideal for material testing labs, research and development and quality control departments.All Porometer 3G Series capillary flow porometers conform to ASTM standard methods D6767, E128, F316-03, and similar and offer the benefits of the pressure sense line and a compact design with the sample holder options external to the control module. Having the sample holder external to the control module allows for measurement of a variety of sample configurations. more...
