Test Types

A Vortex-i PC-controlled torque tester measures the minimum torque before a Luer lock fitting on a syringe barrel begins to rotate.  A versatile set of custom-made fixtures have been designed to fit a range of syringe barrels of different lengths

The force need to move the plunger on medical syringes is measured using a touch-screen controlled MultiTest-xt force testing system. Using a custom-made fixture, the force needed to start the plunger moving, and the average force required to keep it moving down the bore of the syringe are recorded.

The opening torque on containers fitted with child-resistant closures (CRCs) is measured with a Vortex-d motorised torque tester with a top-load capability for applying set loads during torque testing. Using a motorised torque testing system ensures repeatable and accurate test results, in comparison with manual torque testers.  The Vortex-d has been superceded by the Vortex-dV.

This video show a MultiTest 5-xt touch-screen controlled force testing stand being used to test PET bottles for "Top-load". The resistance to crush testing is found together with the individual bottle height. Immediate colour-coded indication of "Pass" or "Fail" is given on the touch-screen. This is an important test in the "downgauging" or "lightweighting" of packaging materials. This is to reduce the amount of material used, reduce costs and to meet environmental standards, but at the same time ensuring the packaging does not fail during the filling, capping and storage process.

This video shows how to set up the MultiTest-xt to measure the height of different sized bottles while at the same time performing a top-load or crush test. The favourite buttons on the touch-screen are used to set the "Home" and "starting position" for each different size of bottle automatically. Upper and lower limits can be entered for both the bottle height and its performance under load, with unambiguous, colour coded "Pass" or "Fail" indication.

Mecmesin's precision torque tester, the Helixa is used to test Luer lock needles fitted to a syringe barrel to a specified torque prior to leak testing the completed assembly.
