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 characterisation of complex pore structures. A more advanced and representative characterisation 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.

Easily to understand and presentable output

With one click of the button, results are exported in word, excel or pdf. The Porometer software makes it very easy to present multiple measurements next to each other, allowing for a straightforward comparison between different filter media. Thanks to the adjustable scales, graphs such as wet and dry curve and pore size distribution are presented in a very clear and sophisticated manner.

Quick, accurate and reproducible results

POROLUX™ BP delivers quick and accurate results of the first bubble point in the pressure range from 0 bar (0 psi) up to 5 bar (75 psi) and detects pores from ca. 300 μm down to 0.13 μm.

Thanks to its simplified operation, the POROLUX™ BP provides highly reproducible results for both the BP x-ml and BP dPL bubble point. This makes the POROLUX™ BP a clear choice for quality control and/or R&D in many companies producing filtration and separation media.

Full automatic detection of Bubble point

The ASTM F-316-03 standard defines the BP as ‘the pressure at which the first continuous stream of gas bubbles is detected’.

While this is based on visual detection, the POROLUX™ BP now offers a fully automated way to determine the bubble point.

Detection of both BP x-ml and BP dPL

The POROLUX™ BP can detect both the BP x-ml and BP dPL bubble point. The BP dPL is the bubble point measured as a deviation from the linearity of a user-defined pressure increase, while BP x-ml is the bubble point measured at a user-defined flow rate.

It is evident that the dPL bubble point generates highly reproducible measurements with correspondingly low scatter. The dPL bubble point is typically very accurate. However, at high pressures, the dPL bubble point can be falsely created by turbulence. In this case, we advise using the BP x-ml.

The instrument determines the bubble point by using digital pressure and flow sensors. In this way, the chance of a human error or the subjective operator’s opinion is eliminated. This helps to standardize the filter media testing in terms of consistency and reliability.

Patent pending MP² technology

MP² stands for Multistage Pressure Process. This innovative technology ensures a smooth pressure increase during the measurement and speeds up the process of reaching flow and pressure stability.

This advanced pressure built-up process makes it possible to do the measurements with smaller, and perfectly uniform pressure steps, leading to the most accurate and reproducible pore size results. Additionally, the technology makes it possible to record more data points in the pore opening region, resulting in more detailed pore size distribution curves.

Step stability method

The POROLUX™ Revo detects the opening of a pore at a certain pressure and waits 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 and allows to calculate the true pore size distribution.

Additionally, the instrument can determine the bubble point in three different ways (largest pore according to ASTM F-316-03), a very unique feature in the market of porometry.

Next to that, results on mean flow pore size, smallest pore, pore size distribution, cumulative flow distribution & gas permeability are reported. With our enhanced mathematical model, we can also obtain additional results such as total pore number and total pore area.

Very intuitive and easy to use software

Not only is the fully integrated software powerful and comprehensive, it is 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.

Last but not least, the POROLUX™ Revo software comes with a very advanced curve smoothing and fitting function.
