SUS304 Stainless Steel Medical Hypodermic Capillary Tube For Injection 10G-34G ISO9626

SUS304 Stainless Steel Medical Hypodermic Capillary Tube For Injection 10G-34G ISO9626

A Stainless Steel Medical Hypodermic Tube is a precision-engineered, cold-drawn, welded stainless steel tube specifically manufactured for medical and surgical applications. This medical capillary tube is made by SUS304 (AISI 304) stainless steel, which is an austenitic chromium-nickel alloy known for its excellent corrosion resistance, formability, and biocompatibility. The SUS304 medical stainless steel capillary tubes are produced to meet the stringent requirements of ISO9626:2016 international standard, which governs dimensions, tolerances, material composition, mechanical properties, and surface finish. The tube size generally ranges from 10G to 34G, and the wall thickness can be regular wall, thin wall, extra-thin wall, etc. In addition to standard tubes, we can also customize non-standard tubes based on the client’s drawings. These medical grade capillary tubes are the primary raw material for manufacturing hypodermic needles, cannula, biopsy needles, catheter mandrels, and other minimally invasive surgical instruments.

The Main Advantages Of SUS304 Medical Capillary Tubes:

• Biocompatibility And Safety: SUS304 is non-toxic, non-pyrogenic, and resistant to bodily fluids, ensuring patient safety and compliance with medical regulations.
• Superior Corrosion Resistance
• Good Mechanical Performance: Excellent combination of high tensile strength and ductility. Allows for precise point grinding (beveling).
• Exceptional Surface Finish: ultra-smooth internal and external finish. This minimizes friction during insertion, reduces patient discomfort, prevents clot adhesion, and ensures accurate fluid flow.
• Dimensional Precision & Consistenc
• Weldability And Formability

Applications:

A. Medical & Surgical Applications (Primary):

• Hypodermic Needles: The core application for injections (subcutaneous, intramuscular, intravenous).
• IV Cannulas: Peripheral venous catheters.
• Biopsy Needles: For tissue sampling (e.g., core biopsy).
• Specialty Needles: Spinal (epidural), orthopedic, ophthalmic, and dialysis needles.
• Catheter Mandrels/Introducers: As the stiffening component for guiding flexible catheters.
• Surgical Instruments: Components for laparoscopic tools, guide wires, and suture needles.

B. Non-Medical Applications:

• Precision Fluidics: Chromatography systems, precision dosing pumps, etc..
• Industrial Probes: For sampling gases or liquids in harsh environments.
• Small-Diameter Mechanical Components: In electronics, watches, and aerospace.
• Guide Sheaths & Protecting Tubes: For optical fibers or fine wires.
