Pressure Scan Method

• Capillary flow gas-liquid porometer
• Designed to deliver fast & reproducible results
• For pore sizes down to 13 nm

The POROLUX™ Cito series are capillary flow gas-liquid porometers (GLP) that determine pore sizes based on the pressure scan method. This is a fast, yet reproducible method whereby air pressure is continually increased while the resulting flow rates are recorded simultaneously.

Key Features:

• Fast, reliable and reproducible measurements

Our POROLUX™ Cito technology stands for fast and reproducible measurements of through pores in filtration and separation media.

The instruments determine the bubble point (largest pore-ASTM F-316), mean flow pore size, smallest pore, pore size distribution,cumulative flow distribution & gas permeability with the highest accuracy in the whole pressure range.

Measurement after measurement, our porometers get you the most accurate and reliable results on the pore sizes of your materials.

• Technology and quality combined

The POROLUX™ Cito series stands out of the crowd with its intelligent sensor switching. This ensures that the most suitable sensor is always engaged throughout the entire measurement.

As a result, very accurate measurements are obtained. Additionally, the porometers allow taking up to 400 real (measured) data points, resulting in the best possible resolution.

• PoreSmart, synonym for smart porometry software

Not only is our 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 PoreSmart 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, the two-stage curve fitting implemented in the PoreSmart software helps extract meaningful results from measuring curves by removing the noises and fitting the curve into a mathematical function that matches best the set of experimental data.

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

• Straightforward and presentable output 

With one click of the button, results are exported in word, excel or pdf. PoreSmart makes it very easy to present multiple measurements next to each other, allowing for a straightforward comparison between different filter media and samples.

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.

Patent Pending Pressure Step Stability Method

• Capillary flow gas-liquid porometer with patent pending MP² technology

• The most accurate pore size results combined with high resolution

• For pore sizes down to 13nm

The POROLUX™ Revo series sets the bar in pressure step stability method with our patent pending MP² (Multistage Pressure Process) technology, while delivering the most accurate and reproducible pore size measurements, in the highest resolution.

Key Features:

• 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.  

• Pressure step stability method 

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

Additionally, the instruments can perform the bubble point test in multiple 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 & gas permeability are reported. With our enhanced mathematical model, we can also obtain additional results such as total pore number and total pore area.
