ISO9626 SUS304 Stainless Steel Hypodermic Needle Tube For Medical Syringe Use 20G 24G 30G
ISO9626 SUS304 Stainless Steel Hypodermic Needle Tube refers to a precision medical-grade capillary tube manufactured from SUS304 (equivalent to AISI 304) stainless steel, which strictly conforms to the ISO 9626:2016 international standard. This standard specifically specifies the requirements for stainless steel needle tubing for the manufacture of medical devices, including hypodermic needles, biopsy needles, and dental needles. YUHONG Group produces stainless steel medical capillary tubes from 10 gauge to 34 gauge, that is, 0.18mm to 3.4mm. We generally cut tubes into 1.5m or 2m, or the client's required fixed length.
SUS304 medical capillary tube is a thin-walled, small-diameter tube with exceptional corrosion resistance, mechanical strength, and formability. Unlike industrial-grade tubes, the medical variant undergoes stricter quality control for:
- Biocompatibility: Non-toxic and non-reactive with bodily fluids or tissues.
- Cleanliness: Free from surface contaminants, oils, and particulates.
- Consistency: Ultra-tight dimensional tolerances to ensure reliable fluid flow and patient safety.
Key Features of Medical Grade Stainless Steel 304 Capillary Tubes:
- Excellent Corrosion Resistance
- High Tensile Strength
- Good Formability
- Non-magnetic (annealed)
- Thermal Stability
- Smooth Penetration
Different Applications of SUS304 Medical Hypodermic Tubes:
- Hypodermic Needles
- Dental Needles
- Biopsy Needles
- IV Cannulas & Catheters
- Surgical Instruments
- Insulin Needles
- Laboratory Devices
- Veterinary Needles
- Micro-dispensing nozzles, precision oilers, electronics cooling probes
