product details

POROLUX Revo is an innovative product of through-hole analyzer. POROLUX Revo adopts our patent pending MP ² (multi-stage pressure process) technology, setting a benchmark for step/balance methods and providing accurate and reproducible aperture measurements at high resolution.


Thanks to its advanced software, using POROLUX Revo to analyze filter media is very simple. The unique features such as built-in intelligence and re evaluation make the instrument very enjoyable to use.


POROLUX Revo is a suitable instrument for characterizing various materials with complex pore structures, such as polymer membranes (flat plates and hollow fibers), ceramic membranes, porous metals, and non-woven fabrics.


Product Features

• Gas liquid, pressure step balance method (using MP ² technology currently under patent application)

Combining the most accurate aperture results with high resolution

Suitable for apertures as small as 13 nm


A wide range of applications

Whether for research and development or quality control purposes, our through-hole analyzer is indispensable for characterizing the pores of various materials

Flat and hollow fiber polymer membranes

Non woven fabrics, precision fabrics, and textiles

Ceramic film and tube

Metal film, porous metal disk, (sintered) metal fiber medium

Specialty paper, etc
