Vortex-I is fully controlled by Mecmesin's flexible, powerful & user-friendly Emperor software & enables quality engineers to develop sophisticated procedures & analyses to meet their particular product testing requirements. One group of tests which are of great significance within the packaging industry involve measuring those torques which characterise the performance of screw closures, caps & lids. Vortex-I is the ideal instrument for: identifying slip torque & bridge torque of tamper-evident closures, determining the release torque of vacuum closures, measuring the peak torque to open a `push and twist' or `squeeze & twist' child-resistant cap, & quantifying the openability of all types of screw closure.
