10G - 34G Disposable Stainless Steel Medical Needle Tube , Tri-Bevelled Tip , ISO7864 SUS304
Stainless Steel Medical Needle Tubes are hollow thin-wall tubes with bevelled tip, and they are available in a full range of gauges from 10G to 34G, designed to form the core shaft of a hypodermic needles, ensuring precision and reliability for diverse clinical applications. These hypoallergenic, corrosion-resistant stainless steel needle tubes are manufactured by medical-grade SUS304/AISI304 raw material and under strict ISO9626 standard, guaranteeing consistent quality and performance. The smooth surface finish minimizes tissue trauma during insertion, enhancing patient comfort. Each needle tube is designed for optimal sharpness and rigidity, making it suitable for various medical procedures including injections, infusions, and diagnostic sampling. The Tri-Bevelled Tip is a needle point ground with three precisely angled facets (bevels) to create a sharp, lancet-like tip that minimizes tissue trauma and improves penetration.
Key Advantages:
- Superior Sharpness & Penetration: The tri-bevel geometry (long primary bevel with two shorter secondary bevels) creates a sharper, more symmetrical point than a standard single bevel, leading to cleaner skin puncture with less drag and discomfort.
- Minimized Tissue Trauma: The lancet bevel tip separates tissue fibers rather than cutting them, promoting faster healing and reduced bruising.
- Material Excellence (SUS304): Offers excellent corrosion resistance, high tensile strength, good ductility for processing, and biocompatibility. It is non-magnetic.
- High Precision & Consistency
- Good Durability: Resists buckling or deformation during injection.
Primary Injection Areas:
The gauge selection directly correlates with the application site:
- 10G-16G: Rare for injection; used for drainage, large-bore aspiration, or specific surgical procedures.
- 18G-22G: Intramuscular (IM) injections (vaccines, antibiotics), intravenous (IV) infusions (for viscous fluids or rapid delivery), blood donation (16G-18G).
- 23G-27G: Subcutaneous (SC) injections (insulin), intradermal (ID) injections (TB tests), standard IV access in adults.
- 28G-34G: Insulin therapy, diabetes management, pediatric and neonatal injections, intravitreal injections (eye), cosmetic procedures, and fearful or sensitive patients.
Choosing Size Based on Application:

Applications
|
Recommended Gauge Range
|
Reasons
|
| Blood Transfusion / Donation | 16G - 18G | Large lumen needed for high flow rates of whole blood. |
| IV Infusion | 18G - 22G | Balance of flow rate and patient comfort. 18G for trauma/surgery, 20G-22G for general fluids. |
| Intramuscular (IM) Injection | 20G - 23G | Sufficiently long and sturdy to reach muscle tissue; can handle viscous solutions. |
| Subcutaneous (SC) Insulin | 29G - 32G (TW/UTW) | Maximizes comfort for frequent daily use; thin wall design ensures adequate flow. |
| Pediatric / Vaccination | 23G - 28G | Minimizes tissue damage in smaller patients. |
| Intradermal (ID) / Allergy Tests | 26G - 30G | Very shallow, precise injection into the dermis. |
| Cosmetic | 30G - 34G | Extreme fineness for precise placement and minimal marks/swelling. |
| Ophthalmic | 27G - 30G | Ultra-sharp tri-bevel is critical for piercing the sclera with minimal deformation and trauma. |
Different Applications:
- Human Body Injection.
- Blood Collection/Testing.
- Veterinary Medicine: Similar range for pets and livestock.
- Biomedical Research: Micro-injections in laboratory animals.
- Medicine Delivery Systems: As a component in auto-injectors, pen injectors, and infusion pump sets.
- Specialty Medical Devices: Components for biopsy needles, spinal needles, and angiography sets.
- Sample Aspiration: Fine-needle aspiration (FNA) for cytology.
