BD Ultra-Fine II Insulin Syringes

For anyone managing diabetes with multiple daily injections, comfort at the needle isn't a luxury — it's the difference between dreading a dose and barely feeling it. BD Ultra-Fine II insulin syringes are built around that reality, pairing a fine 31-gauge needle with the precise unit markings people rely on to dose U-100 insulin accurately at home.

These are U-100 syringes, meaning they're calibrated for standard U-100 insulin — the strength most people in the U.S. use. Matching syringe to insulin concentration is critical, so always confirm your insulin is U-100 before drawing up. Two options in this collection cover different dosing needs. The BD Ultra-Fine Lo-Dose 0.5 mL syringe (31G, 5/16") is designed for smaller doses, with wider-spaced markings that make it easier to read and measure up to 50 units accurately. The BD Veo Ultra-Fine 0.3 mL syringe (31G, 15/64") suits the smallest doses — up to 30 units — and features a shorter 15/64" needle with a short bevel for a shallower, more comfortable injection.

Choosing between them comes down to your typical dose. If you routinely take 30 units or fewer, the 0.3 mL barrel gives you the clearest resolution; if your doses run higher, the 0.5 mL Lo-Dose adds room without sacrificing readability. Both use BD's electropolished, lubricated needle to ease skin entry, and both are sterile, single-use, and disposable — never reuse a syringe, as needle dullness and contamination rise with each injection.

Shorter needle lengths like these are widely recommended for most adults and children because they reduce the chance of an intramuscular injection while still reaching subcutaneous tissue. If you need alternative barrel sizes or gauges, browse the broader BD Ultra-Fine range, or compare the Ultra Fine and Ultra-Fine III collections to find the fit that matches your insulin routine.
