Product Overview
This is a high-precision custom puncture needle crafted from 304 or 316L stainless steel capillary tubing, tailored for applications demanding exact penetration and fluid management. Key manufacturing steps include tapering and reducing the needle diameter for a sharp, durable tip and specific profiles. The body undergoes sandblasting for a uniform, matte, and non-slip finish, marked with clear, permanent graduations for precise depth control. This comprehensive custom machining solution offers excellent biocompatibility and corrosion resistance in challenging environments.
Applications of the Product
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.
