For Parts/ Not Working. This unit powered up and the turbo pump spun up to 90k RPM. It appears it is working but we do not have the expertise to fully test so it's being sold for parts. The back panel is missing, 2 dewar covers have cracked sliders, and the lower door hinges are broken and missing.

      • Features Designed for ease of use:
      • All stations can use 12mm, 9mm or 6mm glassware for maximum flexibility.

      • Automated, independent dewar elevators for each analysis station, plus self-adjusting dewar covers.

      • RTD sensors at each station ensure automatic control of coolant at a level that ensures minimum cold zone and maximum sensitivity.

      • Each of the four analysis ports includes separate and independent dewar (coolant flask) with coolant level sensor, pressure transducer and Po (adsorbate saturated vapor pressure) measurement station for simultaneous measurements yielding maximum throughput and flexibility.

      • Long life dewar flasks for measurements lasting up to 30 hours with liquid nitrogen
      .

      • Choose from two measurement techniques: Patented NOVA® helium-free method or classical helium void volume method.

      • Multiple gas dosing methods to optimize analysis time and resolution:
        1. Standard- Intelligently adjusts dose pressure according to sample demands. 

        2. Vector Dosing - user selectable dose volumes from 0.25 to 10cc per point.

        3. Delta (volume) Max™ - adds data points in regions of large uptake so pore filling step is never missed. 

        4. Dose Wizard™ - can be used with or without QuickMode™ enabled. 
        This allows the instrument to dose more aggressively, saving significant analysis time.

      • Low maintenance, vacuum volumetric system with temperature monitored dosing manifold.

      • Each analysis port can be independently programmed with different analyses and measurement conditions.

      • Stainless steel dosing and sample manifolds with metal-to-metal (VCR) seals.

      • Soft close transparent blue cover protects sample stations and dewars during analysis operation. Opens vertically for easy access to analysis stations, and automatically closes slowly.

      • Communication port for PC control via Windows® based software.

      • Quadrawin™ software ver 3.0+ can operate up to 3 Quadrasorb™ units simultaneously, from one PC.


QUADRASORB evo™ -KR/MP for low surface area and micropore measurements.
    • All of the functions of the standard model QUADRASORB evo™ plus low surface area measurement via Krypton adsorption or low pressure micropore characterization. 

    • Includes low pressure (1 torr) sensor and oil-free turbomolecular vacuum system. 

    • Performs Krypton gas sorption measurements for very low surface area determination, eg. pharmaceutical actives, powdered metals, etc. 

    • Provides low pressure adsorption data (as low as 4 x 10-5 P/Po) necessary for more complete characterization of microporous materials such as zeolites, activated carbons, and molecular sieves.
