BD Micro-Fine Syringe and Pen Needles incorporate Thin Wall Technology (TW). The needles keep their external dimensions extremely fine, but have a wider inside diameter. The result is an improvement in the flow rate, requiring less force to inject the insulin. BD Micro-Fine insulin needles and syringes have a wide range of lengths and gauges adapted to the needs and preferences of everyone who injects insulin. Using the latest in technologies and in combination with proprietary processes and treatments, the BD Micro-Fine range continues to evolve and improve the comfort of insulin injection. Finer gauges, shorter needles, faster flow rates, improved lubrication and easier handling are just a few examples of how the range has evolved. Quantity: 10 Units.
