质构仪注射器测试装置

Syringes are used in hospitals, surgeries and homes around the world on a daily basis, and for a multitude of purposes. Successful administration, as well as comfortable receipt of the material under the skin, rely on the effective tracking of the syringe piston within its outer tube. By testing the ease with which an injectable solution is expressed, manufacturers are able to optimise usability and patient comfort, while guaranteeing quality control and product safety.

Prior to testing, the syringe is held securely in place by a locking insert, which is easily adjusted up to a diameter of 40mm and accommodates a wide range of syringe shapes and sizes. A flat probe, connected to the arm of the TA.XTPlus, exerts pressure on the syringe piston, measuring its resistance to compression. Using Exponent software, a mean force is produced in graph form to provide an average measure of the ease with which the syringe is depressed and fluids are discharged. The universal design of the Syringe Testing Rig also allows manufacturers to determine the force required to remove the plunger from the syringe, thus emulating the ease with which the syringe piston is withdrawn.
