Autoinjector Testing System: Device Changeover and System Alignment
The Instron® Autoinjector Testing System’s fixtures are designed to minimize side loading during cap removal and support common industry device geometries, while offering flexibility to easily accommodate customized devices.
Variability in cap removal force measurements is directly impacted by system alignment and insert design. Instron’s simplified cap removal fixture consists of a common base and device-specific inserts that are easily interchangeable. The base is aligned to the grips and crosshead and does not need re-alignment unless it is removed. To accommodate a new device, the insert is simply changed out using three thumb screws.
System Alignment: In the instances where alignment of the Instron system is required, the alignment procedure, using the included fixture, is simple and repeatable.
Cap Removal Insert: While a range of inserts for the common commercially available autoinjector devices is supplied with the system, the design simplicity makes it easy to machine new inserts for customized devices.
