POROLUX™ BP
Bubble point measurement only
Quick and easy determination of the bubble point
For pore sizes down to 0.1 µm
The POROLUX™ BP is a bubble point tester, used to measure the largest pore size – often referred to as ‘bubble point (BP)’ – in media that are used for filtration and separation applications.
Quick, accurate and reproducible results
POROLUX™ BP delivers quick and accurate results of the 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.

The bubble point is especially important in applications, such as in filtration, when certain solutes must be retained. The POROLUX™ BP offers quick, accurate and reproducible results on the BP x-ml and BP dPL bubble point. This makes the instrument indispensable for quality control and/or R&D in many filtration and filtration media producing companies.
