Frequently asked questions

Why does syringe barrel size matter for insulin?

Dose accuracy. A 1 mL barrel gives more space between graduations than a 3 mL barrel, so small doses are easier to read — which is also why insulin is commonly supplied in dedicated 0.3 mL, 0.5 mL and 1 mL formats.

What does 31G mean?

Needle gauge, or outside diameter: 31G is thinner than 29G or 30G, which usually means less injection discomfort. Thin needles require more care with injection technique.

Can facilities buy syringes without a prescription?

In Canada, the licensing classification of the device determines what documentation a supplier must hold. This listing is being prepared against that requirement; pricing and ordering will be enabled once it is complete.
