Pressure Scan: POROLUX 100, POROLUX 200 and POROLUX 500 Series

The POROLUX™ 100, 200 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 

The pressure scan-series contains instruments with pressure levels that go up to 1.5 bar (22 psi), such as the POROLUX™ 100, or go up to 35 bar (500 psi), such as the POROLUX™ 500. The maximum flow rate can be 200 l/min. For details please see the table of specifications for each model.

Key Features

  • Gas-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.

 

Pressure Step/Stability: POROLUX 1000 Series

The 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.

PRESSURE AND FLOW RATES RANGE 

The POROLUX™ 1000 operates up to 35 bar (500 psi). His maximum flow rate is 200 l/min.

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 
  • Liquid permeability and hydrohead measurements are available as an additional option.
