AutoInjector Test System SA-41
Auto Injector Test System SA-41

The SA-41 semi-automated autoinjector test system from Automationspartner ensures a precise product quality control and is easy to operate. The test system for autoinjectors is designed for GMP production environments. AP also offers the same functionality in automated in-line process control (IPC) systems, integrated into autoinjector assembly machines. Test systems can also be adapted to table top solutions for R&D or laboratory applications.

Optical System Technology


Four autoinjectors are loaded into the machine. The machine collects one product at a time for testing. The protective cap is removed and the force is measured and verified against pre-set values. The vision system triggers a timer when the injection starts and measures the time to completed injection. The length of the needle is measured by the vision system. The dispensed fluid is measured by a precision scale and the volume is calculated automatically from the pre-set liquid density.

Standard Tests

  • Protective Cap removal force
  • Dispensing time of liquid
  • Precise weight of dispensed liquid
  • Needle length during dispensing
