Porous Materials Inc Products - Porometers
Intelligent Porometeripore
Suitable for the measuring and analysis of pore structures of porous materials such as membrane, paper, non-woven, fabric,cartridge,nanofiber(electrospinning fiber), hollow fiber, PTFE…, asthrough poreconstrict pore(include largest pore size, bubble point, pore size distribution), liquid permeability, gas permeability and pore surface area
Feature
- Testing of small samples as well as complete parts
- Many sample geometry (Ex: sheets, rods, tubes, hollow fibers, cartridges, and powders)
- Use of many wetting liquids (Ex: water, alcohol, Silwick, and Galwick)
- Tests in QC, research, or any number of user defined modes
- See-through sample chamber available for visual observation
- Real-time graphic display
- Fully automated and computer controlled
Principle
- Base on Capillary Flow method: ASTM F316-03, F778, D6767-02, BS 3321-1986, 6410
- Where a non toxic wetting liquid is allowed to spontaneously fill the pores in the sample.
- place the sample into chamber and a non reacting gas is allowed to displace liquid from pores.
- As the pressure is increased, more and more smaller pores are progressively emptied. The pressure and flow rate of gas through the emptied pores provides the through pore distribution.
- The pressure at which through pores empty is inversely proportional to the pore size (according to the Washburm calculation equation).
Function
- Mean Pore Size
- Pore Size Distribution
- Pore Flow % Distribution
- Pore Number Distribution
- Bubble Point (the largest through pore throat diameter)
- Bubble Point Mean flow pore diameter (50% of flow is through pores smaller than the mean flow pore)
- Pore Surface Area
- Gas Permeability in many desired units including Frazier, Gurley, Rayl & Darcy
- Liquid Permeability
- Diameter of the most constricted part of a through pore (Pore throat)
