     RDM Test Equipment Ltd is proud to be sponsoring the technical meeting ‘Functional Thin Films’ an annual event held alongside the Vacuum Symposium UK conference and Expo, Coventry 17th Sept 2013.

    Speaker at the conference, Herr Andreas Roos, Technical Applications Specialist from MOCON’s German based Centre of Excellence will present the latest breakthrough in Water Vapour Transmission rate (WVTR) testing.

    The MOCON AQUATRAN® Model 2, is a new system to measure WVTR of ultra-high barrier films, with the highest ever sensitivity of  0.00005  gm.m²/day.

    RDM Test Equipment Ltd is the exclusive distributor of Mocon permeation instruments. From their Hertfordshire base they offer application support, training, instrument sales & service and contract permeation testing.

    MOCON, Inc., the world’s leading manufacturer of permeation and package integrity instrumentation, is launching a new system to measure the water vapour transmission rate (WVTR) of ultra-high barrier films with greater sensitivity than ever before possible.

    The new generation AQUATRAN® Model 2 WVTR measurement instrument targets commercial or developmental ultra-high barrier structures for flexible films in organic light-emitting display (OLED), solar and similar demanding applications, which require accurate and extremely sensitive instrumentation tobuild performance statistics.

    The AQUATRAN® Model 2 uses proprietary technology to accurately and repeatably measure WVTR down to 5 x 10 -5 g/m 2/ day. This is one order of magnitude lower than its very successful predecessor the Model 1 which was launched in 2005. The Model 2 uses propriety technology to increase sensor sensitivity and reduce the possibility of ambient humidity interfering with test results. Further, the AQUATRAN® Model 2 is the only system available for measuring trace WVTR that is not calibration dependent, providing more accurate and repeatable results than calibration dependent methods.

    The AQUATRAN Model 2 utilizes MOCON’s newest AquaTrace® Gold coulometric longer-life sensor which is based on Faraday’s Law.Every water molecule entering the sensor is directly converted to a measureable charge. No calibration is necessary, assuring an accurate test result. Transient data also is quantifiable and can be viewed during or after the test. (Analysis of transient data can yield important information about an OLED structure such as detecting defects and voids in the applied coatings.)

    Additional enhancements to the AQUATRAN® Model 2 include improved electronics; enhanced block and valve design, and the introduction of Tru-Seal technology which reduces seal edge leaks due to ambient humidity. The AQUATRAN® Model 2 is available in two versions.The G system operates between 35 and 90 % relative humidity (RH) and a temperature range of 10 to 40 °C. The W version offers 100 % RH and a temperature range 10 to 50 °C.

  • A breakthrough in Shelf-Life Evaluation and Quality Assurance

    More than 150 years ago, French physician Jean Louis Marie Poiseuille developed a formula for calculating the flow of blood in different parts of the body. At about the same time, German physicist Gotthilf Heinrich Ludwig Hagen independently arrived at the same formula while measuring the flow of water through a tube. What does blood or water flow have to do with 21st century packaging? Plenty!

  • New online seal inspection technology instantly rejects compromised seals.

    Posted on 21/12/2012

    by Phil Neal

    A new online seal inspection technology promises to revolutionise quality assurance for many packagers, especially food, beverage, and healthcare producers that rely on seal integrity for product containment, quality and shelf life. Seal -Scope™ and Seal-Cam™ inspection systems integrate into most existing packaging machines, without any modification. Each generates a unique ‘seal fingerprint’ for every package which, in a few milliseconds, is compared to statistical data to determine pass or fail. Failed seals trigger a signal to an ejector unit.

    The technology, which has been developed by a team of researchers at The University of Leuven, Belgium, is based around a highly advanced statistical algorithm that not only determines pass/fail, it also monitors trends in seal process capability enabling early warnings when pre-set limits are reached. The system is capable of detecting incomplete seals, wrinkles, folds, creases, holes, and product or contaminates in the seal. The sensitivity can be set based on the application and the user’s quality requirements. Learn More...
