Description General description Hypodermic needles are precision made and designed to ensure strict adherence with U.S. Government specification GG-N-196. Points are machine ground to achieve uniform sharpness. Precision grinding, micro-bead jet blasting, and ultrasonic cleaning assure freedom from burrs and debris. All needle cannula are fabricated of type 304 stainless steel tubing which must pass rigorous quality control prior to acceptance and use. Standard nickle plated Luer hubs comply with Luer taper specifications ISO 594. This assures an interchangeable fit mating with Luer slips and Luer locks. Contoured hub cavity facilitates cleaning.
