FAQ

Is this the same product as the BD Ultra-Fine™ II insulin syringe?
Yes. This product was formerly manufactured under the Becton Dickinson/BD brand. Embecta was spun off from BD as a dedicated diabetes care medical device company, and this syringe continues to meet the same specifications and quality standards.

What makes this syringe suitable for Botox and delicate injections?
The 31-gauge ultra-thin needle and 1/2 unit graduations allow for precise, controlled delivery in fine injection applications, making it well-suited for aesthetic and other delicate procedures beyond insulin therapy.

What is the difference between this syringe and the 0.5 mL Ultra-Fine™ II (320468)?
This 0.3 mL version features a finer 31-gauge needle and 1/2 unit graduations, offering greater precision for lower-volume doses. The 0.5 mL version (320468) uses a 30-gauge needle with single-unit graduations, making it better suited for higher-volume insulin doses.

Is the needle permanently attached?
Yes. The permanently attached needle reduces dead space, helping to ensure that the full dose is delivered and minimising insulin waste.

Is this syringe BPA- and DEHP-free?
Yes. This syringe is manufactured without BPA or DEHP, reflecting Embecta's commitment to patient safety.

Is this syringe latex-free?
Yes. Not made with natural rubber latex, making it suitable for patients with latex sensitivities.
