Product Description

Superior Quality 304 316L Stainless Steel Parts for Medical Applications

Product Description
This high-precision custom puncture needle is crafted from 304 or 316L stainless steel capillary tubing, designed for specialized applications needing precise penetration and fluid handling. Key processes include tapering and reducing the needle's diameter for a sharp, robust tip and distinct profiles. The body features sandblasting for a uniform, matte, non-slip surface, plus clear, permanent graduations for precise depth control. Offering excellent biocompatibility and corrosion resistance, this is a comprehensive custom machining solution 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.
