Pharmaceutical & medical


A software-controlled torque tester measuring and comparing the very light twisting effort needed to assemble a Luer lock connector.


twist on a six per cent conical taper. These designs need mechanical testing of the joint between hub and syringe to ensure a leak-free connection and optimal performance under normal use. A complete suite of tests would comprise:


Ease of assembly of the connector.


Axial resistance-to-separation force of the connector.


Connector resistance to separation by unscrewing; torque.


Resistance to overriding of the connector; torque.


Disconnection; unscrewing release torque


Some international standards describe test methods that involve simultaneously applying a defined axial load and torque to the Luer connection, then observing whether it has separated. This requires a unique testing system that can both apply force and measure torque— especially at the low values resulting from small-bore connectors—making the Mecmesin Helixa ideal for testing of this nature.


The final diagnosis


In such a compliance-driven sector as medical and pharma, quality assurance to meet legislative standards in both design and manufacturing functions is a critical condition. With constantly evolving external factors such as the move to more sustainable new materials, cost reduction targets, and product innovation also changing the landscape, ensuring consistent functional performance is a challenge. For confident medical device testing to be as painless as possible, the implementation of a versatile test system with carefully selected accessories is prescribed.
