    MOCON, Inc., the world’s leading manufacturer of permeation instrumentation, has developed a new oxygen transmission rate test instrument which accurately and repeatably measures barriers to 5x10-4cc/(m2 x day), ten times lower than previous levels. The OX-TRAN® Model 2/21 10x system measures films or packages at precise temperature and relative humidity conditions. Learn More...

    Graham’s Colloidal Diffusion illustrates the three-step process of permeation through a material. The first step is the sorption of the permeant into the material. Next, the permeant diffuses through the material followed by the final step where it is desorbed from the other side. This entire process is driven by a concentration difference or gradient. Molecules will permeate from the high concentration side of the material to the low concentration side. This will continue until both sides are at equal concentration levels. Learn More...

  • A new standard in Oxygen Analysis

    The OpTech-O²-Platinum is a non-destructive Oxygen analysis device with 3 test modes for measuring headspace O², dissolved O² in a liquid and barrier film O² permeation properties.

    Because the sensor does not consume any gas, measurements can be repeated on the same pack to create an O² v Time profile over the product shelf life. Applications include modified atmosphere food packaging, beverage containers, and pharma/medical packs, in both R&D and QC environments.


    • Quality Control checks of MAP packs, single value or time profile
    • For liquid contents, measure headspace O² and dissolved O²
    • O² permeation rate of packages & films, including porous & perforated films
    • Very small headspace volume packs, and vacuum packs
    • Determine shelf life for an Oxygen sensitive product
  • 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!
