Calculator

Reconstitution, draw and supply, in one place.

Enter what's in the vial and how much diluent you added. Everything else follows: concentration, the syringe units for a dose, what a given draw delivers, and when the vial runs out. The maths is the same code the Solum app uses, running in your browser. The page makes no requests.

How it's computed

Three lines of arithmetic.

Nothing here is a recommendation. The calculator only rearranges the numbers you give it. Read the full explanation if you want the reasoning behind each step.

  1. concentration = amount in vial ÷ diluent ml
  2. volume = dose ÷ concentration
  3. syringe units = volume × units per ml (U-100 = 100, U-40 = 40)

In the app, this happens automatically.

Set up a vial once and every logged dose shows the draw. Remaining volume updates as you go, and the app warns before a vial runs dry.
