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

The SA-41 automated autoinjector and syringe test system from Automationspartner ensures a precise product quality control and is easy to operate. The SA-41 fulfills requirements by relevant authorities which state that pre-filled syringes and autoinjectors must be tested by the legal manufacturer prior to batch release. 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 our autoinjector assembly lines. Testing of prefilled syringes can be combined in the same platform or can be offered as a stand alone solution.

Autoinjector and Syringe Test System Technology


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 activation force of the device is measured and verified. 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 value.
