Introduction to Syringe Tube Stiffness Tester For professionals in medical device manufacturing, syringe tube stiffness plays a critical role in ensuring the reliability, safety, and usability of hypodermic needles. The Syringe Tube Stiffness Tester, specifically designed to evaluate the stiffness of stainless steel needle tubing, provides a reliable method for quality control and standard compliance. This instrument, such as Cell Instruments’ TS-01, is indispensable for meeting the requirements outlined in ISO 9626. Stiffness is directly linked to mechanical integrity. Tubing that lacks appropriate stiffness may bend, break, or deform during use—posing risks of injury, inaccurate dosing, or contamination. Conversely, overly rigid tubing may fail to provide adequate flexibility, leading to
