IFTS has developed state-of-the-art porometers that integrate advanced technologies for the precise characterization of membranes in various fields such as tertiary water treatment, the biomedical sector and scientific research. This innovation is essential to analyze the structure and function of membranes in detail. The IFTS Fluid-Fluid Porometer is a high-tech laboratory device for measuring pore size distribution up to 4 nm at very low pressure. It is ideal for analyzing various porous materials such as hollow fibers, planar organic membranes, ceramic membranes and cartridges. Its capabilities include determining average pore diameter, studying pore size distribution, measuring solvent permeability, and evaluating bubble point and droplet point.


Two types of tests are carried out with the fluid/liquid porometer: gas-liquid tests, liquid-liquid tests

Principle of the gas-liquid test

A gas is injected into a wet filter medium. The gas pressure is increased and the porometer then measures the differential pressure of the medium as well as the flow rate of the gas flowing through the medium.

Principle of the liquid-liquid test

The filter medium is soaked with test liquid No. 1. The pressure of the No. 2 test liquid is increased and the porometer then measures the differential pressure of the medium as well as the flow rate of the No. 2 liquid flowing through the medium.
