  • The unique stainless steel analysis manifold is corrosive resistant and designed for highly-accurate gas management
  • Improved dewar design provides more than 40 hours of continuous temperature control
  • Available in a krypton capable model for the analysis of very low surface area materials
  • Intuitive MicroActive software gives the user the ability to interactively evaluate isotherm data and reduces the time required to obtain surface area and porosity results
  • User-defined reporting options allow direct modeling
  • Powerful Python scripting language allows users to develop extensions to the standard report library available within the TriStar II PLUS software  application
  • An innovative dashboard monitors and provides convenient access to real-time instrument performance indicators and maintenance scheduling information
  • Capable of utilizing two isoterms (CO2 and N2) for caculating pore size diameter via NLDFT for micropore analyses of carbons

Data Reduction Benefits

  • Interaction with adsorption data is direct. By simply moving the calculation bars, the user is immediately updated with new textual properties.
  • One-click access to important parameters allows the user to focus on the result rather than the parameters
  • Interactive data manipulation minimizes the use of dialog boxes and tunneling of dialogs to specify calculation parameters. This allows the user to accurately and efficiently determine surface area and porosity of their materials
  • Improved ability to overlay files (up to 25) including mercury intrusion data with file add and subtract feature
  • User selectable data ranges through the graphic interface allows direct modeling for BET, t-plot, Langmuir, DFT interpretation, and much more
  • Report Options editor allows the user to define up to five reports with on-screen previews. Each report has the ability to possess multiple summary, tabular, and graphical information pane

 Gemini Series

  The Micromeritics Gemini Series of surface area analyzers rapidly and reliably produces accurate and repeatable surface area and porosity determinations of your sample material. It’s simplicity of use and ruggedness has earned the Gemini its place in laboratories worldwide as an essential tool in both research and quality control environments.Availible with Windows based software or as a key pad controlled instrument

ASAP 2460

The ASAP 2460 Surface Area and Porosity Analyzer incorporates a unique expandable system designed for high-performance and high sample throughput. The base ASAP 2460 is a two-port master control unit. For more throughput, additional two-port units can be connected to the master unit expanding the system to either a four-port or six-port analyzer. The instrument also includes intuitive MicroActive software that combines user-defined reports with the ability to interactively evaluate isotherm

  • All analysis ports can be operated independently and concurrently, allowing the user to load and unload samples at any time, regardless of the analysis stage. A new analysis can begin as soon as another is finished.
  • An analysis in excess of 60 hours can be performed without refilling the dewar. This allows unattended analysis of high resolution adsorption/desorption isotherms that take much longer to complete because the system must equilibrate at each data point.
  • With a master unit and two auxiliary units, BET surface area analyses utilizing six parallel runs can be achieved in as little as 30 minutes.
  • Servo control for dosing and evacuation provides a higher degree of gas management and speeds collection of data points through reduction of dosing overshoot.
  • Up to five different nonreactive adsorptives, plus helium for free space, can be attached to the analyzer simultaneously. Each analysis port can accept a range of sample tube sizes.
  • Long-duration dewars and isothermal jackets assure a stable thermal profile along the length of both the sample and saturation pressure (P0) tubes throughout lengthy analyses. The P0 value can be entered, or measured either continuously or at selected intervals.
  • Intuitive MicroActive software combines user defined reports with the ability to interactively evaluate isotherm data, reducing the time required to obtain surface area and porosity results. User selectable data ranges through the graphic interface allow direct modeling for BET, t-plot, Langmuir, DFT interpretation, and new advanced NLDFT methods
  • In addition to the standard 2460, low surface area krypton and micropore models are available.
    Low surface area (Krypton) model includes the addition of a 10-mm Hg transducer  and permits accurate measurement of very low surface area on materials such as API (active pharmaceutical ingredient), powdered metals, etc. The micropore model includes the addition of a 1-mm Hg transducer which extends the low pressure measurement capabilities and allows enhanced performance for characterizing microporous materials using nitrogen, argon, carbon dioxide, hydrogen, and other fixed gases. The transducer also increases pressure resolution in the range necessary for micropore analysis

 ASAP 2420

  The fully automated ASAP® 2420 Accelerated Surface Area and Porosimetry System is designed for high-performance/high sample throughput to help today’s busy laboratories expand their workflow while providing highly accurate and precise surface area and porosimetry measurements. With six independently operated analysis ports, a new analysis can begin as soon as another is finished. This provides an important advantage over many multi-port instruments that require all samples to be prepared or analyzed at the same time. In addition, a key, standard feature of the ASAP 2420 is a programmable and fully automated sample preparation module with twelve independently operated ports. Samples may be added or removed from degas ports without disturbing the treatment of other samples undergoing preparation or analysis.

ASAP 2050

  The ASAP 2050 Xtended Pressure Sorption Analyzer is an easy-to-use instrument capable of collecting high-resolution, high-pressure adsorptive isotherms from vacuum to 10 atmospheres. While retaining
many design elements of the popular ASAP 2020, the ASAP 2050 offers an extended range of capabilities that enables the instrument to obtain data in an elevated-pressure environment. The instrument is particularly well suited for fuel cell, hydrogen storage, and pressure swing adsorption research applications.
