The Pressure Scan Series

porolux500

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.

(1) Depending on the wetting fluid

  • 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.

STANDARD SAMPLE HOLDERS

All POROLUX porometers come with a 25 mm sample holder. Other standard sample holders have a diameter of 13 or 47 mm.

3-IN-1 SAMPLE HOLDER

A uniquely designed sample holder which makes it easier than ever to switch to a larger sample holder in case you have dense or non-homogenous samples, or to switch to a smaller sample holder when working with samples with high gas permeability. The 3-in-1 simply includes all three common samples asizes (13 mm, 25 mm and 47 mm) in one!

SAMPLE HOLDER FOR 25 MM DIAMETER FOR THICKER SAMPLES

  • Sample holder for samples of thickness up to 10 mm.
  • Maximum pressure: 35 bar.
  • Also available for 13 mm diameter samples.
  • HOLLOW FIBRE AND TUBULAR SAMPLE HOLDER (SHHF)

    The characterisation of the pore distribution of hollow fibres and tubes requires relatively high pressures and a limiting factor is often the burst pressure of the hollow fibre. Therefore, safety is often as concern.

    We have developed a stainless steel sample holder in which one or more hollow fibres can easily be glued. With this sample holder very reproducible results can be obtained.

    • The pressure can be applied from the outside to the inside or vice versa
    • Maximum pressure: 35 bar*
    • Includes replaceable O-rings
    • Resistant to silicone and epoxy glues
    • Easy cleaning of the assembly

    *This is the maximum pressure that the hollow sample holder can withstand. The maximum pressure allowed in each experiment will depend on the mechanical resistance of the hollow fibre.

    IN-PLANE POROMETRY SAMPLE HOLDER

    Special parts and accessories to carry out in-plane porometry measurements. Only available for 47mm sample holders.

    POROMETER can create costumer specific designs for special samples: thick samples, large diameter samples, assembled filter-setups, etc. Please contact us for details and price.
