How it works
Step 1: Use the stock concentration to prepare an intermediate solution (concentration + volume).
Step 2: Dilute the intermediate solution to your final concentration and final volume.
Formula
Step 1: Cstock × Vstock = Cinter × Vinter
Step 2: Cinter × Vinter-used = Cfinal × Vfinal
Clinical safety note: Always verify dilution steps against product information and local policy. Label intermediate solutions clearly (concentration, date/time, diluent).
