Mocon has developed the Ox-Tran Model 2/21 10x system, a new oxygen transmission rate test instrument said to measure barriers accurately and repeatably to 5x10-4 cc/(m2 x day), ten times lower than previous levels.
According to the US-based scientific instrumentation company, the Ox-Tran Model 2/21 10x system measures films or packages at precise temperature and relative humidity conditions, and is ideal for a variety of applications which require increasingly better oxygen barrier solutions.
Improved material barrier systems have created a demand for increased testing sensitivity, Mocon says, and brand owners and suppliers require accurate and repeatable results in order to make sure performance criteria are being met.
“There are a number of improvements engineered into the Ox-Tran Model 2/21 10x Module to take oxygen permeation testing to a new level,” says Doug Lindemann, vice president, Mocon.
“The most important is the improved proprietary Coulox coulometric sensor which counts every oxygen molecule permeating through the film.”
This, Lindemann adds, is the reason why Mocon has “the only” system which complies with the ASTM D3985 test method standard.
Other improvements incorporated into the new system include: improved electronics to reduce system ‘noise’ level; new TruSeal film cell design to eliminate edge-leakage and assure perfect sealing; improved temperature stability.
Each Ox-Tran Model 2/21 10x module contains two test cells and is available in master and satellite configuration – the 10x module connects with all other modules in the Ox-Tran2/21 family of transmission rate test systems.
