Accelerated Surface Area and Porosimetry System


Sophisted Design, Intuitive Operation, Research-Grade Results

The Micromeritics ASAP 2020 Plus integrates a variety of automated gas sorption techniques into a single, but powerful, table-top instrument. The system is designed to provide high-quality surface area, porosity, chemisorption and physisorption isotherm data to materials analysis laboratories with ever-expanding analytical requirements. The ASAP 2020 Plus provides maximum versatility over a remarkable range of applications to meet your specific needs.

With more installed instruments in more countries for more users, the ASAP family of products have proven to be the instruments of choice worldwide when researchers require precise, high-quality gas adsorption data.


Unique and Innovative Isothermal Jacket Cold Zone Control

Isothermal jackets are guaranteed for the life of the instrument and ensure a constant thermal profile along the full length of both the sample and saturation pressure (P°) tubes.


Advanced Capabilities through Optional Configurations

The ASAP 2020 Plus can be configured to your specific needs with the option of upgrading at a later date as your analytical requirements change, maximizing the utility of this instrument and your investment. Choose from low surface area, to heated vapor, to micropore capability. Add a cryostat, an external detector, or configure the unit for enhanced chemical resistance when working with aggressive vapors. The ASAP 2020 Plus permits one instrument to accommodate almost any surface characterization need in your lab.


Design Versatility
  • Two independent vacuum systems permit simultaneous preparation of two samples while analyzing another. This maximizes your personnel productivity and your return on time invested
  • Continuous saturation pressure (P°) monitoring and unique Isothermal Jacket Cold Zone Control provide a stable thermal environment for both saturation pressure and adsorption. Spend time on results instead of controlling temperature variations
  • The ASAP 2020 Plus is configurable with many optional accessories to meet your specific analytical requirements


ASAP 2020 Plus Physisorption

Research grade results in a customer-configurable instrument to meet a wide variety of applications for mesopore, micropore, and low surface area applications

  • Programmable two-station degas system for automated SOP sample preparation
  • A dedicated P° sensor allows for a faster analysis and provides P° values at the same conditions as the adsorption measurement
  • Six analysis gas inlets with dedicated vapor and helium free-space ports provide greater flexibility and automated selection of pretreatment, backfill, and analysis gases
  • Proven Isothermal Jacket Cold Zone. Control provides accurate, reproducible temperature maintenance
  • Long duration and refillable dewar provides virtually unlimited time-of-analysis capability
  • Standard, independent dual vacuum systems (one for analysis, one for sample pretreatment). Also available is an optional, oil-free system
  • Proprietary transducer system provides unequalled stability, fast response, and low hysteresis for improved accuracy and signal to noise improvement
  • Coated monolithic, temperature-controlled, stainless-steel manifold provides non-contaminating, inert surface areas


MicroActive for ASAP 2020 Plus – Interactive Data Reduction Software

Micromeritics’ innovative MicroActive software allows you to interactively evaluate isotherm data. You can easily include or exclude data, fitting the desired range of experimentally acquired data points using interactive, movable calculation bars. The isotherm can be viewed real-time on either a linear or logarithmic scale, available to you under each calculation model.
