Introducing OX-TRAN 2/40 OTR Analyzer for Whole Package Testing

AMETEK MOCON Launches OX-TRAN® 2/40 Oxygen Permeation Analyzer for Whole Package Testing of Cups, Trays, Pouches and Other Forms
AMETEK MOCON, a leading global provider of permeation analyzers, package testing instruments and gas controllers/sensors, has launched a new analytical instrument to measure the oxygen transmission rate (OTR) of whole packages under precisely controlled environmental conditions.
The new OX-TRAN® 2/40 Oxygen Permeation Analyzer for OTR measurements targets package permeation testing for food, beverage and healthcare packaging applications in which knowing the precise oxygen ingress through a package is critical to a product’s shelf life. Applications for the OX-TRAN 2/40 include permeation testing of thermoformed trays, bottles, flexible pouches, corks, caps, and more.
Historically, testing the oxygen permeation of whole packages either suffered from poor control of the test gas conditions, since the package was tested in room air, or required cumbersome set up of an independent environmental chamber that was often difficult to use. Adding to the complexity of legacy package permeation testing, package samples needed to be epoxy adhered and heat removed from reusable plates.
“With the new OX-TRAN 2/40, whole packages can now be accurately tested for OTR values at controlled humidity and temperature conditions. Samples are changed easily with a new methodology. The chamber is large enough to accommodate and simultaneously test four large packages, each about the size of a two-liter soda bottle,” explains Phillip Tan, Director of Strategic Marketing for AMETEK MOCON.
Additionally, this analyzer uses our next generation software platform with automated controls and simple touchscreen display. "The industry finally has a permeation instrument that is designed for accurate and easy package testing,” he concludes.
The OX-TRAN 2/40 utilizes MOCON’s industry-standard coulometric sensor, so no calibration is required, and it complies with ASTM F1307 for OTR measurements.For more information on the OX-TRAN 2/40 please click here
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.
