Innova Ultra-Nano Porometer

Series: Innova Ultra-Nano Porometer (UNP / iUNP)

  • Innova Ultra-Nano Porometer is a combination of Capillary Flow Porometer (gas-liquid method) that measure large pores of 500 um to 0.013 um and has liquid-liquid Porometer function to accurately measure much smaller pores.
  • The Innova-UNP is the only commercially available pore size measurement system which can accurately measure pores from macro, micro, ultra and nano range.
  • Capillary Flow Porometer and Liquid Liquid Porometer in a single machine
  • Measures Through Pores from 2 nm to 500 um
  • Mean Pore Size, Bubble Point (Largest Pore), Pore Distribution
  • Cumulative Filter Flow % and Liquid Permeability

According to ASTM F316-03

  • Where a nontoxic wetting liquid can spontaneously fill the pores in the sample and a non reacting Gas (Liquid) can displace liquid from pores.
  • First the largest pores will get emptied, as they require lower pressure than smaller pores.
  • As the pressure is increased, more and more smaller pores are progressively emptied.
  • The pressure and flow rate of Gas (Liquid) through the emptied pores provides the through pore distribution. The pressure at which through pores empty is inversely proportional to the pore size.
  • Through pores are the pores connected from one side of material to the other side. Innova Porometer measures the pore throat diameter, which is the most constricted part of the entire pore path.
