Product Description
Crafted from 304 or 316L stainless steel capillary tubing, this high-precision custom puncture needle is tailored for specialized uses demanding exact penetration and fluid management. Key processes include tapering and reducing the diameter for a sharp, durable tip and specific profiles. The surface is sandblasted for a uniform, matte, non-slip finish, marked with clear, permanent graduations for precise depth control. It offers a comprehensive custom machining solution with excellent biocompatibility and corrosion resistance for demanding conditions.
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.
