What syringe should I use?
A 1 mL U-100 insulin syringe is the standard choice for most research draws. For very small draws (below 5 IU on the U-100 scale), a 0.3 mL or 0.5 mL syringe gives finer resolution. The calculator returns the exact draw volume in both mL and IU for any vial size and target dose.
