  • RDM Permeation Lab achieves near perfect results!

    Our Mocon Permeation Lab recently achieved near perfect results in the Hemshell Proficiency Testing service for OTR and WVTR.

    Labs from across the world took part in proficiency testing for Oxygen Barrier and Water Vapour Barrier on plastic films. In both cases the RDM lab reported near perfect results, for OTR (an error of 0.011 cc/m2/day) and for WVTR (an error of 0.08gm/m2/day) for films in the range of 0.2 and 2 respectively. All Mocon instruments in our lab are regularly maintained and checked using NIST traceable films so the results didn't come as a surprise.

    If you are dealing with barrier films, you might find our lab service useful to check one or more batches of film. Prices start from a few hundred pounds.

  • Mocon launches AQUATRAN 3

    Posted on 11/10/2017

    by Phil Neal

    The next generation AQUATRAN Model 3 WVTR measurement instrument targets ultra high barrier materials that are engineered to push the performance envelope. These include flexible films for organic light-emitting diode (OLED) displays, solar panels and similar demanding applications, which require accurate and extremely sensitive instrumentation to confirm performance attributes.

    The use of OLEDs for consumer electronics, such as televisions and photovoltaics for solar panels, are growing exponentially. However the electronic components within OLED displays are extremely sensitive to water vapour. The slightest exposure to humidity can cause a series of problems that significantly decrease a product's usable life. The AQUATRAN Model 3 with its easy to use interface, puts the testing capability into the hands of a wider user base.

    The AQUATRAN Model 3 measures each molecule of water vapour that passes through the sensor, and requires no calibration. The response is linear throughout the entire measurable range of the sensor, so measurements of ultra barrier materials are guaranteed to be highly accurate and repeatable.
