Test System combines leak and seal testing.
Lippke 2500 SL measures both pressure loss and burst pressure. Leak testing can be conducted on flexible, semi-rigid, and rigid packages, while seal strength tests can be conducted on flexible and semi-rigid packages. Offering test documentation such as graphs, measurement database, and statistics, system is suited for quality control/quality assurance monitoring, raw material qualification, and...Read More »
Tester indicates water vapor transmission rate.
PERMATRAN-W-® Model 398 provides alternative for testing of medium- to high-barrier structures. Operating via WinPerm(TM) software, unit enables 2 films to be tested simultaneously at 2 different RH conditions. Automated temperature and relative humidity controls, as well as automatically determined equilibrium, minimize chance of operator error. Modular system offers two 50 cm-² test cells and...Read More »
Headspace Analyzer suits quality control applications.
Portable PAC CHECK-® Model 325 oxygen and carbon dioxide analyzer measures controlled and/or modified atmospheres in food packages. Sticky Foot(TM) probe houses needle internally for protection. Tacky septum, attached to bottom of probe, rests against package. Needle is actuated by twisting outer housing which allows it to penetrate package, thereby measuring internal gas levels. Analyzer...Read More »
Testing/Consulting Services evaluate films and packages.
Testing and consulting services for flexible, semi-rigid, or rigid films and finished packages include odor analysis, permeation analysis, and O2 and H2O vapor transmission rates. Services available offer evaluation of microbiological activity, taste panels, and distribution studies, where, after primary package testing is concluded, company tracks performance through distribution cycle....Read More »
Test Systems measure water vapor and O2 transmission rates.
OX-TRAN-® Model 702 and PERMATRAN-W-® Model 700 feature COULOX-® coulometric-type sensor for measuring oxygen and modulated infrared sensor for measuring water vapor. Seven-cell configuration allows 7 different structures to be tested independently. Pushbutton-actuated, pneumatic clamping device facilitates loading of material into cell and provides consistent pressure. Systems are suited for...Read More »
