Features
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.
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.
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
