Product introduction
PMY-100N is a laboratory instrument developed in accordance with relevant injection-needle standards to evaluate rigidity and toughness of disposable injection needles. It is suitable for testing dermal, subcutaneous, intramuscular and intravenous disposable needle tubes, pre-pot-sealed syringe tubes and other straight stainless-steel medical needles.

Product standards

• GB 15811-2016 Disposable Sterile Injection Needle
• YBB00112004-2015 Pre-potting Syringe Assembly (with needle)
• YBB000992004-2015 Stainless Steel Injection Needle for Pre-potting Syringes
• GB/T 18457-2015 Stainless Steel Syringes for Manufacturing Medical Devices

Equipment characteristics

• 7-inch color touch screen for intuitive operation
• Three-level user management to meet GMP traceability
• Configurable tests to cover rigidity and cyclic toughness requirements
• Cost-effective design with high-precision force sensor
• Large-capacity storage for test results and parameters
• Full numeric keypad for sample classification and quick settings

Test principle
Rigidity: Apply a specified force at the center of a supported span of the needle and measure needle deflection.
Toughness: Fix one end of the needle, apply cyclic bending from a fixed point over a specified span—bend to a set angle in one direction, then to the opposite direction—for a defined number of cycles to assess fatigue resistance.
