Product Overview
This custom puncture needle, crafted from premium 304 or 316L stainless steel capillary tubing, is designed for specialized applications demanding precise penetration and fluid control. Key manufacturing includes tapering and diameter reduction for a sharp, durable tip and specific profiles. It features a sandblasted, uniform matte finish for a non-slip grip, with clear, permanent graduations for depth accuracy. This is a full custom machining solution, offering excellent biocompatibility and corrosion resistance for challenging environments.
