Product Description
This high-precision custom puncture needle is crafted from 304 or 316L stainless steel capillary tubing, designed for applications needing precise penetration and fluid handling. Key processes include tapering and reducing the needle's diameter for a sharp, robust tip with specific profiles. The body is sandblasted for a uniform, matte, non-slip finish, and marked with clear, permanent graduations for accurate depth control. This comprehensive machining solution provides excellent biocompatibility and corrosion resistance for rigorous environments.
Product Applications
Medical & Veterinary: Biopsy needles, fluid aspiration/injection, epidural/anesthesia needles, ophthalmic surgery, micro-invasive procedures.
Industrial & Scientific: Precision fluid sampling (e.g., chromatography), probe needles for testing, micro-dispensing, and specialized fluidic system connections.
