High Throughput Gas Separation (HTGS)

The new High Throughput Gas Separation (HTGS) system is a device designed to run up to 16 different membrane-based separations of variable single and mixed gas feeds simultaneously. Up to 5 gases (O2, CO2, CH4, N2, and H2) can be mixed at a set flow. The on-line analysis option permits screening mixed gas selectivities, in comparison to single gas permeation experiments.


The automatic film coater MEMCAST™ is ideal for the synthesis of flat sheet polymeric membranes by coating a thin film with a polymer solution followed by the immersion of the films in a coagulation bath to obtain the final membrane via wet phase inversion. Reproducible film layers can be prepared, either self-standing (e.g. coating directly onto glass, stainless steel, etc.) or on various substrates (e.g. nonwoven, polymeric supports, etc.).

The design minimizes movement during film application in order to obtain smooth and consistent films. It is robust, durable, easy to clean, and very user-friendly.


The 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 a very accurate measurement of pore sizes and allows a calculation of the real pore size distribution.


The POROLUX™ 100, 200, 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 fibers, etc.


The pressure scan series contains instruments with pressure levels that go up to 1.5 bar (22 psi), such as the POROLUX™ 100 or go up to 35 bar (500 psi), such as the POROLUX™ 500. The maximum flow rate can be 200 l/min. For details please see the table of specifications for each model.

Liquid Permeability Tester (LPT 400)

The Liquid Permeability Tester (LPT 400) is designed to determine the liquid permeability and the Silt Density Index (SDI) in technical materials in a pressure range between 50 mbars and 4 bars.

A fully automatic program runs the selected test. The liquid is collected in a receptacle and the weight recorded by a balance is automatically transferred to the operating software, which calculates the liquid permeability.


The POROLIQ™ 1000 is a Liquid Liquid Porometer (LLP). This rapid, precise method employed by the POROLIQ™ 1000 allows for testing of pore size down to 2nm and, compared to other techniques, uses lower pressures for characterisation of traditional micro-, nano-porous materials.


The POROLUX™ 50 is our newly developed first bubble point (FBP) tester, and is used to detect only the largest pores (FBP) in filtration and separation media. With a pressure going up to 5 bar (75 PSI), the instrument is able to detect pores down to 0.1 µm.


The High Throughput (HT) dead-end filtration module for single feed liquid filtration, SPIDER™ is built in stainless steel and it is suitable for both water and solvent-based feed solutions. In one single experiment, it is possible to carry out either 8 or 16 simultaneous dead-end filtrations (depending on the SPIDER™ model), which supposes an extreme gain of time compared to conducting the same experiments one by one with a single cell.
