Vial reconstitution maths
Calculate from vial amount and diluent volume to understand the resulting concentration.
A Crux Horizon product
VialVault Calculator
A focused standalone utility for vial reconstitution, concentration, draw volume, and U-100 syringe calculations.
Enter a vial amount, diluent volume, and intended amount to calculate concentration and the draw volume needed for that intended amount — including a clear U-100 syringe visualisation. Calculations run on-device for the active session.
Why it exists
A simple tool for a specific calculation task.
Reconstitution and dose-conversion maths are easy to get wrong when switching between mg, mcg, millilitres, and syringe units.
VialVault Calculator keeps that workflow purpose-built: enter the values you already have, review the calculated concentration and draw volume, and inspect the corresponding U-100 syringe measurement — without accounts, history, or cloud sync.
Core capabilities
Built for one clear calculation workflow.
Each capability supports fast, on-device reconstitution and dose conversion.
02
Intended amount to draw volume
Convert an intended amount into the draw volume required for that calculation.
03
U-100 syringe visualisation
Review calculated results alongside a clear U-100 syringe measurement view.
mg and mcg input support
Select milligram or microgram units for vial amount and intended amount fields.
Concentration results
See concentration expressed in both mg/mL and mcg/mL from the values you enter.
On-device calculation
Values are processed in memory for the active session. The app does not store calculation history.
Privacy approach
Calculation stays on the device.
VialVault Calculator does not use accounts, analytics, advertising, or cloud sync. Calculator inputs and results are processed in memory for the active session and are not transmitted by the app.
