Beckman Coulter LS 13 320 XR Laser Diffraction Particle Size Analyser 21 CFR Part 11

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.

The Porolux BP excels in pore size analysis by precisely determining the largest pore size through bubble point measurement. This pore size analysis technique involves assessing the pressure at which gas displaces liquid from the largest pores, providing accurate data on pore structure. Ideal for characterising materials like membranes, filters, and powders, the Porolux BP ensures reliable results for both research and industrial applications. With its advanced technology, the Porolux BP delivers detailed pore size analysis, enhancing material performance evaluation and quality control processes. This makes it an essential tool for accurate and comprehensive pore size analysis.

  • Key Features

    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.

  • Good service, very helpful

    We use Meritics for the PM service and installation of all our FlowCams . Megan has been coming to our site for a number of years. She is very efficient in her work, but most of all Megan is very helpful. We have had issues with one of instruments after the install and Megan did her utmost to try and solve it while on site, even though it wasn’t solved Megan has been in contact with the supplier of the instrument to try and solve this problem for us.

  • Good Service

    David, our service engineer as usual was good at communicating and setting up the recent service appointment, he arrived on time, did the service promptly and informed me of any problems. Friendly and helpful

    TomA-446

  • Superb and prompt service

    I have used this company through the laboratory I work for frequently. We specialise in soil analysis, and Meritics were chosen as they have extensive knowledge of the instruments we use. We have several laser particle diffraction analysers with a service contract, and service is always very prompt and meticulous….

  • Good experience over two years

    Meritics have covered the annual servicing of our Multisizer 4e instrument since we purchased it from them just over two years ago. The application scientist who performed the servicing was friendly, knowledgeable, and extremely helpful, happily answering a barrage of questions about how best to use and maintain the instrument. All my interactions with Meritics staff have been positive. I would happily recommend them.

  • Highly recommend Meritics for equipment purchases and aftercare services

    After owning one of our instruments for over 8 Years which was purchased from Meritics, it suffered its first breakdown. Upon contacting Meritics, I was instantly put through to an engineer who was very helpful. Upon inspection of the manual, it was decided that it would be more cost effective to have a Meritics engineer visit. The Meritics staff were very communicative and kept me up to date.

  • Excellent Service

    Lovely, friendly and extremely helpful. David and his team are always on call with advise and are very easy to work with and are always happy to help.

  • Professional, Customer-oriented, fast service

    We had issues with one of the aperture tubes provided by Meritics on a Friday afternoon, while very pressed for a review deadline. Meritics handled our inquiries very fast and professionally and helped us out by shipping us their spare tube to use in the mean time free of charge, while we waited for our new tube to arrive. Communication was very pleasant.
