Zwick’s test device for automated testing of injection pens (e.g. insulin pens)
is based on a zwicki-Line Z0.5 TN table-top testing machine with additional torsion drive, allowing the various operations of the pen to be tested using a single device. In this way the dosage setting, release force, stroke and the dose dispensed are all measured in one continuous process. The test device can be combined with a robotic specimen feed system and the test methods
using either or both axes can be combined as required.
