Gas Liquid Porometry
 

Porolux 100

 

The POROLUX™ 100/100NW/100FM and 500 are gas liquid porometers based on the pressure scan method developed for the rapid measurement of through-pores in materials such as filters, nonwovens, textiles, paper, membranes, hollow fibres, etc.

 Pressure and Flow Rates Range 

Starting from instruments that go up to 1.5 bar (22 psi), such as the POROLUX™ 100NW, up to 35 bar (500 psi), POROLUX™ 500. The maximum flow rate can be 100 or 200 l/min depending on the model and the application. For details please see the table of specifications for each model.

Key Features

  • as-liquid displacement porometer based on the pressure scan method: the applied pressure and the resulting gas flow are measured continuously.
  • Full flexibility with the highest accuracy in the full pressure range (up to 35 bar/ 500 psi).
  • Very fast and reproducible measurements of first bubble point, maximum pore size, mean flow pore size, minimum pore size, pore size distribution and gas permeability.
  • Ideal for quality control work.

 POROLUX™ 1000 series comprises research grade gas liquid porometers for the rapid measurement of through-pores in porous materials based on the pressure step/stability method. The target pressure is achieved by combining an inlet valve for the gas, which generates the initial pressure, and a specially designed needle valve, which subsequently adjusts very precisely the pressure. The pressure and flow sensors will only take a data point when the user defined stability algorithms are met for both pressure and flow. In this way, the POROLUX™ 1000 detects the opening of a pore at a certain pressure and waits until all pores of the same diameter are completely opened before accepting a data point. This results in very accurate measurement of pore sizes and allows a calculation of the real pore size distribution.

Key Features

  • Gas-liquid displacement porometer based on the pressure step/stability method. It detects the opening of pores at a certain pressure and holds the pressure stable  until all pores of the same diameter are open (flow through the sample is also stable) before accepting a data point. 
  • Very accurate and reproducible measurements of  first bubble point, maximum pore size, mean flow pore size, minimum pore size, pore size distribution and gas permeability.
  • Ideal for research and development work.
  • Determination of the true FBP: measured bubble point (read more)
  • Liquid permeability and hydrohead measurements are available as an additional option.
