24 mg vial + 2 mL bacteriostatic water: units chart
A 24 mg vial mixed with 2 mL of bacteriostatic water holds 12,000 mcg per mL. This is a strong mix: each unit holds 120 mcg, so small doses take up only a few units and are harder to measure. More water would spread them out.

- Convert the dose to mcgmg × 1,000 = mcg0.25 mg × 1,000 = 250 mcg
- Concentrationvial (mcg) ÷ water (mL) = mcg per mL24,000 mcg ÷ 2 mL = 12,000 mcg/mL (12 mg/mL)
- Volume to drawdose (mcg) ÷ concentration (mcg/mL) = mL250 mcg ÷ 12,000 mcg/mL = 0.0208 mL

Worked example: 1,250 mcg
- Convert the vial amount to mcg: 24 mg × 1,000 = 24,000 mcg
- Concentration: 24,000 mcg ÷ 2 mL = 12,000 mcg/mL (12 mg/mL)
- Volume to draw: 1,250 mcg ÷ 12,000 mcg/mL = 0.1042 mL
- Units to draw: 0.1042 mL × 100 units/mL = 10.4 units
- Amount in each unit: 12,000 mcg/mL ÷ 100 units/mL = 120 mcg per unit (0.12 mg)
- Doses in the vial: 24,000 mcg ÷ 1,250 mcg = 19 full doses
Draw 10.4 units on a U-100 syringe, just above the 10-unit mark. The same 1,250 mcg dose is 7.8 units with 1.5 mL of water and 13 units with 2.5 mL of water, compared with 10.4 units with 2 mL.
Frequently asked questions
What is the concentration of a 24 mg vial with 2 mL of water?
A 24 mg vial mixed with 2 mL of water holds 12,000 mcg per mL. Each unit on a U-100 syringe holds 120 mcg.
How many units is 1,250 mcg with a 24 mg vial and 2 mL of water?
It is 10.4 units on a U-100 syringe, which is 0.1042 mL of the mixed liquid.
What is the smallest dose you can measure well with a 24 mg vial and 2 mL of water?
About 240 mcg, which fills 2 units on a U-100 syringe. Smaller amounts are hard to read; a vial mixed with more water spreads them over more units.
What is the largest dose that fits a 1 mL syringe with a 24 mg vial and 2 mL of water?
12,000 mcg, which fills all 100 units of a 1 mL U-100 syringe. Larger doses need more than one draw or a stronger mix.
How many doses does a 24 mg vial with 2 mL of water give?
Divide 24,000 mcg by your dose and round down: 19 full doses of 1,250 mcg, or 16 of 1,500 mcg.
