ISO9626 SUS304 Stainless Steel Medical Capillary Tube For Surgical Needle Tube , 10G - 34 G

ISO9626 SUS304 Stainless Steel Medical Capillary Tube refers to a small-diameter, precision-engineered hollow tube made from SUS304 (equivalent to 304 or 1.4301) austenitic stainless steel. It is manufactured in strict accordance with the ISO 9626 international standard, which specifies the requirements for stainless steel tubing intended for the manufacture of medical devices. Medical capillary tubes are characterized by their very small internal diameters and precise wall thicknesses. Unlike standard tubing used in industrial applications, medical capillary tubes must meet stringent requirements for biocompatibility, dimensional accuracy, and surface cleanliness. They serve as the fundamental building blocks for a wide array of medical instruments, acting as conduits for fluids, gases, or as structural components for surgical tools. YUHONG GROUP produce medical grade stainless steel capillary tubes from 10 Gauge to 34 Gauge. As for non-standard capillary tubes, we can also customize according to clients’ request.

Chemical Composition Table (Medical Grade SUS304):

Key Features of Medical Grade Stainless Steel 304 Tubes:

• Corrosion Resistance: The chromium oxide layer provides excellent resistance to bodily fluids and sterilization processes.
• Strength and Ductility: The cold-working process allows for a tailored balance of stiffness (for penetration) and ductility (for forming without breaking).
• Precision Dimensional Control: Maintains tight tolerances critical for fluid flow rates and component assembly.
• Excellent Surface Finish: Minimizes friction and improves fluid dynamics.

Different Applications of SUS304 Medical Capillary Tubes:

• Hypodermic Needles: The most common application, used for injections, blood collection, and biopsies (e.g., 21G-27G for standard injections, 30G-34G for insulin or ophthalmic use).
• Catheters and Cannulas: Used as the shaft material for over-the-needle catheters, introducing fluids or draining bodily fluids.
• Surgical Instruments: Found in laparoscopic tools, trocars, and micro-surgical instruments for cutting, grasping, and suction.
• Dental Equipment: Used for anesthetic delivery needles (27G-30G) and irrigation tips.
• Biopsy Devices: Core biopsy needles require thin walls and a sharp cutting edge, provided by precision tubing.
• Drug Delivery Systems: Implantable ports and infusion sets rely on these tubes for precise fluid pathways.
• Guidewires and Stylets: While guidewires are solid, they are often housed within a capillary tube (introducer).
• Gas Chromatography: Used in medical analyzers for precise sample handling.
