    Description

    Introduction
    The permporometer is an instrument that allows to measure the through pore size distribution in UF membranes. It is based on the controlled pore opening by evaporating condensed liquid by stepwise decreasing the vapor activity in the gas stream over a membrane surface.

    Principle
    Pores that are not of the same size will open at different values of partial pressures, with the biggest ones opening first, inverse capillary condensation.

    Applications
    Determination of active pore size distribution in ultrafiltration membranes between 1.5 – 60 nm.
