POROLUX™ Cito series
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.
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 curve are presented in a very clear and sophisticated manner.

(*) BP x-ml is the bubble point measured at a user-defined flow rate. BP pCF is the bubble point measured as a user-defined percentage of the cumulative flow.
Universal sample holder 3 in 1
Sample holder 3 diameters in 1 (13, 25 and 47 mm).
Hollow fibre sample holder
Specially designed sample holder for hollow fibres, including 5 sealant rings.
Sample holder of 25 mm diameter for thicker samples
External sample holder for samples of thickness up to 10 mm.
Customer specific solutions
Porometer can also create customer specific sample holders to meet special requirements, such as measuring thick samples, samples with larger diameters, working with assembled filter setups, etc.
The POROLUX™ Cito L & M are the reference in R&D and quality control environments to characterize 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.
