POROLIQ™
The POROLIQ™ is a Liquid Liquid Porometer (LLP). This rapid, precise method employed by the POROLIQ™ 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 MOST ACCURATE LLP ON THE MARKET
- Based on the pressure step/stability method: a data point is only recorded when the user-defined stability algorithms are met for both pressure and flow.
- 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.
- The POROLIQ™ AQ uses a combination of three ultrasensitive liquid flow sensors to measure exactly and accurately flow rates from 0.16 μl/min (to detect the displacement of wetting liquid out of the pores from the very beginning).
- Ideal for full characterization of hollow fibers at low pressures.
