3Flex Physisorption – Surface Characterisation Analyzer

3Flex Physisorption – Surface Characterisation Analyzer

Micromeritics | Surface Area and Pore Size

The 3Flex Physisorption is a high-performance instrument for mesopore and micropore analyses which delivers superior accuracy, resolution, and data reduction. All analysis stations can be configured for micropore and are also available with krypton analysis for low surface area materials.


  • Three configurable analysis ports adapt to the specific needs of your workflow
  • Research-grade instrument provides superior mesopore/micropore, physisorption, or chemisorption analyses. Ports can be configured for krypton analysis of low surface area materials
  • Vapor sorption capability
  • Ultra-clean manifold design features hard-seal valves and metal seals to provide high chemical resistivity, ease of evacuation, and lowest outgasing rate in the industry
  • Isotherm data collection begins in the 1 o-6 torr range (10-9 relative pressure range for N2)
  • MicroActive™ Data Reduction software provides powerful, yet intuitive, data analysis
  • Advanced dosing method permits user to combine pressure and volume increments
  • Small footprint conserves valuable lab bench space
  • Analyze a sample with 3 separate adsorbent gases simultaneously, one at each port in a single analysis
