Witt Gas Techniques has launched LabOx, a new non-invasive O2 measurement analyser for use with Modified Atmosphere Packaging (MAP) in the food processing and packaging industries, including for fresh foods.
Witt Gas, a Warrington-based gas safety, control, mixing and analysis equipment supplier, has launched LabOx to measure the oxygen concentration in sealed packages, including blister packs, using multiple checks over a period of time with the added ability of being able to measure oxygen in headspace and dissolved liquids. It measures oxygen levels using oxygen quenching of a fluorescent dye in transport, translucent and semi-translucent packages, bottles or containers, as long as the material can transmit light in the 470nm and 610nm range.
The system can be used in R&D and quality control departments, for oxygen permeation, shelf life, oxidation and oxygen scavenger studies, as well as MAP integrity. It allows packaging companies to monitor every package as it comes off the production line, and as it passes through the distribution chain, without the need to continually extract samples, open or destroy bottles or sealed closures, reducing operating costs and expensive returns.
Other advantages of the system include automatic data logging, integrated temperature compensation and easy operation.
