MEMBRANE & FILTER TESTING
Liquid Permeability Tester
The Liquid Permeability Tester (LPT 400) is designed to determine the liquid permeability & the Silt Density Index (SDI) in technical materials in a pressure range between 50 mbars and 4 bars.
The liquid is first collected in a receptacle; the weight recorded by a balance is automatically transferred to the operating software, which calculates the liquid permeability. SILT DENSITY INDEX (SDI) SDI measures the percent drop per minute in the flow rate of water through a filter, averaged over a period of time.

DEAD-END FILTRATION CELLS
The dead-end filtration module for single feed liquid filtration (stirred cell) is built in stainless steel. It is suitable for both water or solvent based feed solutions.
All stirred cells are provided with porous metallic support grids, NBR and EPDM rubber O-rings to ensure tight sealing. To assure full functionality with feeds of diverse chemical nature, different types of specifically designed rubber O-rings from the respective brands are also available. |
FEATURES
Internal magnetic stirrer bar ensuring a homogenisation and reducing concentration polarisation and membrane fouling Full safety models available up to 40 bar Membrane diameter 52mm Includes a CE marking certificate |
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 HTGS is sold in an entire package. Please contact us for more information. |
FEATURES
Pressure Range 0-35 bar Flow Range 0-10 l/min for individual gases up to 30 l/min for gas mixtures Temperature Range maximum 80 ºC Individual Sample Area 2.24 cm² Resolution (pressure and flow sensors) 24 bit |
High Throughput Membrane Testing
The High Throughput (HT) dead-end filtration module for single feed liquid filtration.
Built-in stainless steel and it is suitable for both water or solvent based feed solutions. In one single experiment it is possible to carry out either 8 or 16 simultaneous dead-end filtrations, which supposes an extreme gain of time compared to conducting the same experiments one by one with a single cell. The HT dead-end filtration module is flexible and can be used for many applications such as water desalination. Please contact us for more information. |
FEATURES
Common feed reservoir for the multiple membranes tested in the same run. Magnetic stirring ensuring a homogenisation and reducing concentration polarisation and membrane fouling. Total feed volume on demand. Full safety models available up to 40 bar Optional heating by using a hot stirrer bottom plate. |
