Product Description
This product is a high-precision, custom-designed puncture needle made from 304 or 316L stainless steel capillary tubing. It is crafted for specialized uses demanding precise penetration and fluid management. Key processes include tapering and reducing the needle's diameter for a sharp, robust tip and specific profiles. The body features a uniform, matte, non-slip sandblasted finish, marked with clear, permanent graduations for precise depth control. This comprehensive machining solution ensures excellent biocompatibility and corrosion resistance in demanding 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.
