MOCON, Inc. has introduced added CO2 capabilities with the launch of its new MultiCheck® 425—a new, combination testing system for packages with one-way degassing valves.

The latest instrument in the MultiCheck® series measures headspace carbon dioxide (CO2) in addition to oxygen (O2). The unit also measures leak detection, seal strength and one-way degassing valve performance via MOCON’s new Valve Test Unit™ (VTU).

Because five different tests are combined into one unit, the MultiCheck® 425 system significantly impacts time, labor and samples needed to conduct individual testing.

Instead of destroying five different packages to conduct the same number of tests, a single package cycles through all of the tests on one unit. First the O2 and CO2 headspace analysis, followed by the pressure decay leak test, then a seal-strength burst test and finally the valve test, which tests both the leak and the seal strength of the valve.

Anthony Ahmed, product manager at MOCON, reflected, “By performing all of the tests on one package, the new system provides the first true profile of the condition of a single package vs. trying to get an overall perspective by looking at results from five different samples.”

In addition to the new valve tester, the MultiCheck® 425 is based on the marriage of two separate MOCON technologies—its Lippke® 4500 (leak detection/seal strength) and its hand-held Pac Check® 325, O2/CO2 headspace analyzer.

“As the global gold-standard leader in instrumentation technology, we are always looking for ways we can positively impact our customers’ productivity,” explained Ahmed. “This new combination unit will significantly reduce testing time, while providing the same accurate results.”

The MultiCheck® 425 unit is ideally suited for flexible packages with degassing valves, with applications including coffee, pet food, agricultural chemicals, resins, medical and others which require pressure relief.
