Dilution Ratio at 57% stock concentration: a worked example

What does the result look like when stock concentration reaches 57%? The full calculation is worked below with real intermediate numbers. planning a dilution from concentrate to target strength before batching or transfer

The inputs for this scenario

  • Stock (starting) concentration: 57 % (raised for this scenario; the documented default is 50)
  • Desired working concentration: 12.5 % (unchanged)
  • Concentration basis conversion factor: 1 x (unchanged)

Working through the calculation

  • Applying the documented formula (Dilution ratio = starting concentration ÷ target concentration × conversion factor) to the inputs above produces each figure below.
  • At this operating point the engine returns 4.56 x for required dilution ratio, the number this scenario is built around.
  • At this operating point the engine returns 4.56 value for raw concentration ratio.
  • At this operating point the engine returns 1 x for basis conversion factor.
  • At this operating point the engine returns 12.5 value for target concentration.

How this compares with the baseline

  • Against the tool's baseline example, where stock concentration sits at 50% and the headline result is 4 x, this scenario comes in 14% above the baseline at 4.56 x.
  • A figure at this level is achievable when stock concentration is genuinely sustained, not just peaked for a shift. It assumes ideal volume additivity and a linear concentration basis; strong acids and some polymers show volume contraction or nonlinear activity that this simple ratio does not capture.

Results at a glance

  • required dilution ratio: 4.56 x (headline result)
  • raw concentration ratio: 4.56 value
  • basis conversion factor: 1 x
  • target concentration: 12.5 value
