The OX-TRAN 2/28 Series of oxygen permeation analyzers with unique 4-cell capability can test four barrier samples at the same time providing twice the throughput of traditional OTR instruments. The new dual film horizontal cartridge is removable for easy sample preparation and the user-friendly operator interface provides real time status of testing against target limits.
Highest Accuracy
- Patented COULOX® sensor is the only absolute Coulometric sensor on the market, never requiring calibration
- Low detection levels down to 0.05 cc/(m2*day)
- Fully automated temperature and flow controls simplify testing and provide unparalleled repeatability
High Throughput
- Industry's fastest sensor response time allows shorter overall test times
- Dual film removable test cartridges allow testing of 4 samples at a time requiring less space
- Automated test method can start a test by a single press of a button
- TruSeal gas flushed perimeter sealing can eliminate the need for absolute zero in many tests thus shortening overall test times
The OX-TRAN 2/28 Series high throughput analyzers can test the Oxygen Transmission Rate (OTR) on films from low to high barriers without humidification. It uses MOCON’s patented COULOX absolute (intrinsic) coulometric sensor requires no calibration and is the base for the ASTM standard D3985. This analyzer provides very accurate and repeatable test results within a wide detection range from 0.05 to 200 cc/(m2*day).
The 4-cell capability allows for triplicate testing with or without a reference film in the same test. The option to run a known standard as a control improves the confidence in the results. With 4 cells and its simplified operation the OX-TRAN 2/28 Series is well-suited for quality control laboratories performing a high volume of OTR tests.
The analyzer has industry leading features such as removable horizontal test cartridges, fully automated testing providing higher throughput in the lab and a QC test mode with real time display of testing status against target limits. It is available with a touch screen operator interface or without one where the control is via a local computer with the same easy to use color graphic interface.
For more than 25 years, MOCON’s OX-TRAN series of instruments have been the most trusted and longest lasting on the market. The OX-TRAN 2/28 Series is the perfect choice for the busy laboratory routinely performing shortened or abbreviated permeation tests.

Test Methodology
Following
ASTM D3985
Standard Test Method for Oxygen Gas Transmission Rate Through Plastic Film and Sheeting Using a Coulometric Sensor
The test specimen is mounted as a semi-barrier between two chambers at ambient atmospheric pressure. One chamber is slowly purged by a stream of nitrogen and the other chamber contains Oxygen. As Oxygen permeates through the film into the nitrogen carrier gas, it is transported to the coulometric detector where it produces an electrical current, the magnitude of which is proportional to the amount of oxygen flowing into the detector per unit of time.
