Oxygen permeability tester. PackPerm is our model for measuring the oxygen transmission rate (OTR) through pouches, bags, little containers, PET bottles, natural or synthetic corks, screw and bottle tops, bag-in-box and other products for packaging application. Measures can be carried out both in air at room conditions and in 100% oxygen. PackPerm is offered in double cell version. At request it is possible to enclose the new technique of measure­ments patented by ExtraSolution that allows to reduce until 4 times the duration of a typical analysis.
