BD Ultra-Fine U100 Insulin Pen Needles, are engineered to be thinner and smoother for a more comfortable and less painful injection. Becton Dickinson Ultra-Fine™ needles are sculpted to create a flatter, thinner surface that helps penetrate the skin with significantly greater ease for a smoother and gentler injection. Electro-polishing away microscopic burrs gives every needle a smooth finish. Every Ultra-Fine™ pen needle tip is cut as finely as possible for easier penetration using a 5-bevel cut for a sharper point. Clinical trials support improved patient comfort, easier insertion and overall preference.Features and BenefitsFor use with U-100 InsulinNeedles are made with surgical steelNeedles are 5-bevel cut for a sharper pointNeedles are electropolished to remove burrsThin wall cannulas (needle) for easier flowFilm coated for maximum comfortColor-coded to gaugeEasy-to-read information on each side of the boxNot made with natural rubber latexClear polypropylene hubGamma irradiation sterilizedSpecificationsCompatibility: Most “Type A” Pen Injector DevicesBrand: Beckton DickinsonPen Needles Size ChartNeedle TypeGauge (G)Needle LengthMPN (Retail Box)MPN (Mail Order)Nano32G (0.23mm)5/32in (4mm)320122320883Nano32G (0.23mm)5/32in (4mm)320550320574Micro32G (0.23mm)15/64in (6mm)320749N/AMini31G (0.25mm)3/16in (5mm)320119320882Short31G (0.25mm)5/16in (8mm)320109320881Original29G (0.33mm)1/2in (12.7mm)328203320880Difference between Retail Box and Mail Order (MO) BoxWhile both options contain the same high-quality BD Ultra-Fine U100 Pen Needles the key differences come down to packaging and quantity:Retail Box: Comes in a more consumer-friendly, visually appealing package, typically found in retail stores.
