Porosity Analyzer: The Micromeritics Tri-Star II (surface area) with Micrometrics VacPrep 061 (Sample Degas System)

The Micromeritics Tri-Star II Surface Area and Porosity Analyzer allows for the analysis of surface area and porosity of powders or other nano-structures.

The Micrometrics VacPrep 061 Sample Degas System prepares samples for surface area and pore structure analysis. It offers two methods for removing contaminants such as water vapor and adsorbed gases from samples to avoid interference with surface area measurements: flowing gas method, and a vacuum mode which prepares samples by heating and evacuation.


Micromeritics Tri-Star II Surface Area and Porosity Analyzer (BET)

  • Three independent analysis ports operate simultaneously
  • Minimum surface area to measure: 0.01 m2/g (with Kr)
  • Adsorbate gas for specific surface area test: N2 (available) or Kr (upon request)
  • LN2 test temperature
  • Data points: 5-1000
  • A dedicated Po port allows for measurement of saturation pressure on a continuous basis
  • Saturation pressure can be entered manually, measured continuously, or collected over the sample

Micromeritics VacPrep 061 Sample Degas System

  • Six sets of sample kits: sample tubes (1/2” O. D.), filler rods, seal frits, tube holders, isothermal jackets
  • Heating block temperature: up to 400 ºC, with accuracy ±5 ºC
