POROLUX™ 1000 series comprises research grade gas liquid porometers for the rapid measurement of through-pores in porous materials based on the pressure step/stability method. The target pressure is achieved by combining an inlet valve for the gas, which generates the initial pressure, and a specially designed needle valve, which subsequently adjusts very precisely the pressure. The pressure and flow sensors will only take a data point when the user defined stability algorithms are met for both pressure and flow. In this way, the POROLUX™ 1000 detects the opening of a pore at a certain pressure and waits until all pores of the same diameter are completely opened before accepting a data point. This results in very accurate measurement of pore sizes and allows a calculation of the real pore size distribution.

Key Features
- Gas-liquid displacement porometer based on the pressure step/stability method. It detects the opening of pores at a certain pressure and holds the pressure stable until all pores of the same diameter are open (flow through the sample is also stable) before accepting a data point.
- Very accurate 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 research and development work.
- Determination of the true FBP: measured bubble point (read more)
- Liquid permeability and hydrohead measurements are available as an additional option.
