Liquid Liquid Porometer

Innova Hydro Fluid Porometer

Model: HFP-100 / HFP-200 / HFP-500

  • The Hydro Fluid Porometer is a next generation Porometer based on Liquid Liquid displacement method. The Innova HFP can measure pore size distribution and pore structure analysis of various porous materials with ease.
  • The testing method is Liquid-Liquid displace test function.
  • It is suited for R&D and QC in industries worldwide such as filtration, nonwovens, pharmaceutical, biotechnology, healthcare, household, food, hygienic products, fuel cell, water purification, and battery. Samples often tested include filter media, membranes paper, powders, ceramics, battery separators and health care products.

According to ASTM F316-03

  • Where a nontoxic wetting liquid can spontaneously fill the pores in the sample and a non reacting Liquid can displace liquid from pores.
  • First the largest pores will get emptied, as they require lower pressure than smaller pores.
  • As the pressure increases, an increasing number of smaller pores are progressively emptied.
  • The pressure and flow rate of 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.

 

Application: Non-woven, Electrospinning, Glass fiber, Filter paper, Membrane-MF/UF/NF, Hollow fiber, Hemodialysis, Ceramic, Sintered metal, PTFE, Battery Separator, Fuel cell GDL
