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