Syringes are complex assemblies composed of different materials—polypropylene barrels, elastomeric stoppers, stainless steel needles, and polymer-based luer locks. These materials must function together under mechanical stress, fluid pressure, and time-sensitive delivery demands.
Ensure smooth, consistent movement and sealing performance with comprehensive plunger testing methods.
Validate syringe barrel strength and flange durability to prevent breakage under clinical stress.
Needle Test Assess needle sharpness, stiffness, bond strength, and safety for reliable injection performance.
Tip & Luer Lock Test Verify secure connections and leak-proof performance of syringe tips and luer lock systems.
Barrel Test Measure critical barrel parameters including leakage resistance, dead space, and dimensional stability.
Every component of the syringe must be validated for performance under stress, pressure, and sterilization conditions.
From raw components to finished syringes, we offer complete test coverage.
