Cardiogen Reconstitution Calculator (20 mg vial)
Worked example
With 20 mg of Cardiogen in 2 mL, the concentration is 20 / 2 = 10 mg/mL. A 250 mcg example amount (0.25 mg) needs 0.25 / 10 = 0.025 mL, or 2.5 units on a U-100 syringe, and 20,000 mcg divided by 250 mcg gives 80 aliquots per vial.

How it works
- Concentration = vial mass / water volume: 20 mg / 2 mL = 10 mg/mL.
- Aliquot volume = target amount / concentration: 0.25 mg / 10 mg/mL = 0.025 mL.
- Units on a U-100 syringe = mL x 100 = 2.5.
- Aliquots per vial = vial mass in mcg / target amount = 20,000 / 250.
Frequently asked questions
How much water does a 20 mg vial of Cardiogen need for 10 mg/mL?
Concentration is vial mass divided by water volume: 20 mg / 2 mL = 10 mg/mL. Change the water volume in the calculator to see how the concentration and the syringe reading move together.
How many units on a U-100 syringe is a 250 mcg example amount of Cardiogen?
At 10 mg/mL a 250 mcg example amount is 0.025 mL, which is 2.5 units because 1 unit on a U-100 syringe equals 0.01 mL.
How many 250 mcg aliquots are in a 20 mg vial of Cardiogen?
20 mg is 20,000 mcg, and 20,000 mcg divided by 250 mcg gives 80 aliquots, before allowing for volume lost to priming and syringe dead space.
