Disposable Syringe Needles for LUER-LOK type syringes fit our disposable syringes, reusable syringes and our glass syringes. The stainless steel needles have a standard wall thickness and uses a poly hub that has an aluminum insert to increase needle strength and comes in a variety of gauge diameters and lengths. The larger the needle gauge, the smaller the needle diameter (a 16 gauge needle has a larger diameter opening than a 22 gauge needle). Unless otherwise noted, all needles are BEVEL tipped. Blunt Tip Needles are available in 18 and 20 gauges only. With proper care and cleaning, these syringe needles can be reused many times over. Our disposable syringe needles are packaged in 10, 25 and 100 quantity packs.
