zwickiLine for Flexible Low-Force Testing.
The test fixture is used to determine the breakaway force and glide force of syringes, syringe cartridges, and similar drug-delivery systems. The glide force test is based on the standards DIN EN ISO 7886 -1, DIN EN ISO 11499 and ISO 11040-4. The breakaway force and glide force are important parameters used in the selection of suitable syringes. These forces may not exceed or fall below certain limits to ensure that a safe drug dose is administered. The forces are influenced by the viscosity of the drug and the size of the cannula.
With its adjustable specimen holder, the ZwickRoell universal test fixture can accommodate all common syringe geometries. Specimen diameter adjustment is performed steplessly and tool-free via a handwheel. Optional holders facilitate the testing of specimens without finger grips. In conjunction with the testXpert III testing software, the maximum force and averaged glide force can be easily determined. The integration of a weigh module makes it possible to determine the dosing accuracy of single doses, such as those in insulin cartridges. A camera documents the glide force of the syringe plug. The videoCapture plus option for testXpert III synchronously records the test results and the video signal. Together with the non-contact videoXtens extensometer, continuous measurement of the thickness of the plug is also possible.
