POROLUX™ Cito series

  • Gas-liquid technology
  • Designed to deliver fast & reproducible results
  • For pore sizes down to 13nm

Key Features of the POROLUX™ Cito

The POROLUX™ Cito series are 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.

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 first 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.

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.

Typical Applications for the POROLUX™ Cito

The POROLUX™ Cito L & M are the reference in R&D and quality control environments to characterise media with larger pores such as nonwovens and textiles. Thanks to its broader measurable pore size range, the POROLUX™ Cito is used to measure a wider variety of filtration and separation materials, including membranes, both in R&D and quality control.
