LIQUID LIQUID POROMETRY

The POROLIQ™  is a liquid-liquid porometer (LLP) that determines pore sizes based on the pressure step stability method. This means that a data point is only accepted on the condition that the user-defined stability algorithms for pressure and flow are met.

Complete and accurate measurements 

The POROLIQ™  – widely regarded as the most accurate liquid-liquid porometer on the market – is very well suited to detect very small pores, as well as to characterize pressure sensitive membranes such as hollow fibers.

The instrument will first detect the opening of a pore at a certain pressure but will wait until all pores of the same diameter are completely opened before accepting the data point. This method results in a very accurate pore size measurement, down to 2 nm, and allows to calculate the true pore size distribution.

Technology and quality combined

All our porometers are designed and manufactured in-house, enabling us to equip our instruments with the best and latest technology. 

The POROLIQ™ stands out of the crowd with its intelligent sensor switching, making sure that throughout the entire measurement the most suitable sensor is always engaged, resulting in very accurate measurements. Additionally, the Porometer is equipped with a highly advanced, multilevel stability algorithm for characterization of complex pore structures. A more advanced and representative characterization of your through pores is not possible!

Very intuitive and easy to use software

Even though our software is powerful and comprehensive, it’s also very intuitive and easy to use.

By allowing to change many parameters with a click of the mouse, the software enables its many users to tune the measurement to their exact needs. Additionally, the software, with built-in intelligence, gives the user access to many advanced functions, such as the re-evaluation function and the observation window.

Furthermore, our porometers are equipped with an onboard ethernet port allowing remote access via the internet for installation, support, and diagnosis.
