Syringe Guide

Insulin syringes are marked in units, not milliliters. They are U-100, meaning 100 units = 1 mL.

30-unit vs 100-unit

  • 30-unit (0.3 mL): finer graduations, ideal for small draws.
  • 50-unit (0.5 mL): a middle option.
  • 100-unit (1 mL): holds the most, coarser graduations.

Reading the draw

If a calculation says “draw to 25 units,” pull the plunger to the 25 mark. The calculator shows the exact unit mark and visualizes it on a syringe diagram.
