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.

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.
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.

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.
*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.
