Serial Dilution Calculator

Science & Engineering

Cₙ=C₀/Dⁿ · step dilution · MIC & ELISA plates

Quick Answer

Serial Dilution Calculator: Cₙ=C₀/Dⁿ · step dilution · MIC & ELISA plates. Serial Dilution Calculator uses standard science & engineering formulas to compute accurate results instantly.

How it works

  1. 1Cₙ=C₀/Dⁿ; total dilution = Dⁿ
  2. 2Ten-fold ladder: 1:10 → 1:100 → 1:1000 → 1:10000
  3. 3Each step: 1 part stock + (D-1) parts diluent
  4. 4For CFU counts, plate the dilution giving 30-300 colonies

Total dilution factor：10,000 ×
Ladder：1.00e+3 → 1 → 10 → 1…
Pipette ≥100 µL per step to control error (it compounds n-fold); always change tips — carryover inflates concentrations. Two-fold ladders (D=2) serve MIC/serology; ten-fold for CFU counts. For an accurate low-concentration working stock, dilute once from source rather than stepping down.
