SUS304 ISO9626 10 - 34G Stainless Steel Medical Capillary Tube For Medication Administration

SUS304 ISO9626 10 - 34G Stainless Steel Medical Capillary Tube For Medication Administration

The Medical Capillary Tube is a high-precision, small-bore, hollow tubular component manufactured from SUS304 medical grade stainless steel in compliance with the stringent ISO9626 standard. It is engineered specifically for medical and pharmaceutical applications where precise and reliable fluid transfer is critical. It serves as the fundamental structural component in a vast array of single-use and reusable medical instruments, which is ideal for integration into devices like hypodermic needles, cannulas, micro-catheters, and drug delivery systems. YUHONG GROUP is the leading manufacturer and supplier of medical grade stainless steel capillary tubes, whose sizes rang from 10G to 34G(0.15mm - 3.4mm). Our capillary tubes are complied with ISO9626 international standard with smooth surface and strict size tolerance. We can also process the capillary tubes into semi-finished needle tubes with ground needle tips according to the client’s drawing or sample. Our factory has auto grinding machines and semi-auto grinding machines to meet clients’ high-volume requirements.

Surface Finish:

The surface finish is crucial for minimizing friction during insertion and ensuring cleanliness.

• Inner & Outer Surface: A smooth, bright annealed (BA) finish is standard. This is achieved by annealing in a controlled atmosphere (hydrogen) to prevent oxidation, resulting in a clean, smooth, scale-free surface with low roughness (Ra value often < 0.8 µm).
• Cleanliness: Tubes are ultra-cleaned and packaged in a cleanroom environment to be free of oils, particles, and other contaminants.

Key Features of Medical Grade SUS304 Capillary Tubes:

• Excellent Biocompatibility: SUS304 is widely accepted and tested for medical applications.
• Superior Corrosion Resistance: Resists body fluids, saline, and many medications.
• High Mechanical Strength & Ductility: Provides necessary rigidity for penetration while allowing for bending/kinking resistance.
• Exceptional Dimensional Precision & Consistency: Guaranteed by ISO9626, essential for automated assembly and device performance.
• Superb Surface Finish: Low-friction surface reduces patient trauma and ensures smooth fluid flow.
• Non-Toxic & Non-Pyrogenic: Manufactured and cleaned to avoid introducing toxins or fever-causing agents.
• Ease of Secondary Processing: Ideal for subsequent steps like pointing (needle tip formation), grinding bevels, welding hubs, and electrolytic polishing.

Different Applications of SUS304 Capillary Tubes:

• Hypodermic Needles & Syringe Needles: The core material for all standard injection needles.
• Intravenous (IV) Cannulas: For venous access.
• Biopsy Needles: For tissue sample extraction.
• Micro-Surgical Instruments: Components for ophthalmic, neurological, or cardiovascular tools.
• Drug Delivery Systems: Components in insulin pens, auto-injectors, and infusion pump sets.
• Guide Wires & Stylets: As the outer sheath or core wire.
• Suturing Needles: Hollow needles for specialized suturing techniques.
• Dental Injection Needles.
• Laboratory & Analytical Instrumentation: Where precision fluidic paths are required.
