Product Description

Customizable 304 Stainless Steel Sandblasting Needle for Various Applications

Product Description
Custom Processed 304 Stainless Steel Tube Mitsubishi Graduated Needles, high-precision medical and laboratory instruments with distinctive graduated scale for volume measurement. Made from premium 304 stainless steel tubing, these needles feature precision-etched Mitsubishi-style graduations for visual volume reading during fluid aspiration/injection. The sandblasted matte finish boosts scale legibility, minimizes glare, and allows permanent laser marking of IDs, gauge sizes, or lot numbers. Ideal for single-use or limited-reuse, these needles offer healthcare and laboratory professionals precise volumetric control, corrosion resistance, and reliable performance in critical fluid handling.
