This calculator aids the preparation of fluids where a
ready-made solution of the desired concentration is not available.
Replace the example values with ones appropriate for your requirements to get the formulating instructions.
Notes:
The additive concentration can be higher or lower than the initial concentration in the fluid bag, depending on whether you are trying to increase or decrease the final concentration
Standard IV fluid bags are overfilled by an average of ~5-15% depending on their size. The following table has mean volumes for standard bags that can be used in the Fluid bag volume (mL) calculation fields below:
Labelled Standard Volume

50 mL
57 mL
100 mL
108 mL
250 mL
265 mL
500 mL
533 mL
1000 mL
1035 mL
