Medical injection needle rigidity tester

• 

The Medical Injection Needle Rigidity Tester is designed to evaluate the mechanical rigidity of medical injection needles. It measures deflection and load under controlled conditions, ensuring that needles meet required standards for patient safety, comfort, and performance. The instrument supports a wide range of needle specifications and wall types, providing precise, repeatable results for manufacturers, laboratories, and regulatory testing.

Application

The tester is suitable for rigidity testing of medical injection needles in the following industries and products:

(1) Medical Device Manufacturing: Quality control of single-use, sterile injection needles.

(2) Research & Development: Testing new needle designs, wall thicknesses, and mechanical properties.

(3) Regulatory & Certification Labs: Compliance testing according to national and international standards.

(4) Third-Party Testing Organizations: Verification of needle rigidity for certification and reporting.

(5) Educational & Training Institutions: Demonstration and training on needle testing protocols.

Standards

The instrument is compliant with the following standards, including relevant international regulations:

(1) GB 18457-2001 – Medical Injection Needle Rigidity Performance Testing Standard

(2) ISO 7864:2016 – Sterile Hypodermic Needles for Single Use – Requirements and Test Methods

(3) ASTM F899-16 – Standard Test Method for Determining Needle Rigidity and Flexibility

(4) EN ISO 9626:2016 – Stainless Steel Needles for Medical Use – Mechanical Requirements

Features

(1) Precision compliance: engineered to meet global medical standards

(2) High accuracy: deflection measurement ±0.01 mm, load control ±0.1 N

(3) Versatile: supports needle diameters 0.3–3.4 mm and wall types (normal, thin, ultra-thin)

(4) User-friendly: automated testing, simplified setup

(5) Durable construction: compact, robust design (25 kg) with lifetime standard upgrades

(6) Adjustable span distance: 0–55 mm with ±0.5 mm accuracy

(7) Controlled loading speed: 1 mm/min ±0.1 mm/min

(8) Ergonomic design: compact footprint (460 × 340 × 400 mm) for laboratory efficiency
