Product Description
This high-precision custom puncture needle is crafted from 304 or 316L stainless steel capillary tubing. Designed for specialized applications requiring precise penetration and fluid handling, it features key manufacturing processes such as tapering and reducing the needle's diameter for a sharp, robust tip and specific needle profiles. Finished with sandblasting for a uniform, matte, and non-slip surface, it is marked with clear, permanent graduations for accurate depth control. A comprehensive custom machining solution, it offers excellent biocompatibility and corrosion resistance, perfect for demanding environments.
Product Applications
Medical & Veterinary: Ideal for biopsy needles, fluid aspiration/injection, epidural/anesthesia needles, ophthalmic surgery, and micro-invasive procedures.
Industrial & Scientific: Perfect for precision fluid sampling (e.g., chromatography), probe needles for testing, micro-dispensing, and specialized fluidic system connections.
