Dilution Calculator Formula Guide
Use C1V1 = C2V2 to estimate final concentration and diluent volume.
FormulaC1V1 = C2V2
Formula
Dilution formula
Use appropriate lab safety, measurement precision, and protocol rules for real solutions.
C1V1 = C2V2
25 mL of 10x stock diluted to 250 mL gives 1x final concentration.
FAQ6 common questions for this calculator.
FAQs
Do concentration units matter?+
Use the same concentration unit for stock and final concentration.
What is diluent?+
Diluent is the added liquid needed to reach final volume.
How does the Dilution Calculator calculate the result?+
For the Dilution Calculator, it uses the Dilution formula: C1V1 = C2V2. 25 mL of 10x stock diluted to 250 mL gives 1x final concentration.
What information do I need to use the Dilution Calculator?+
For the Dilution Calculator, enter the known quantities requested by the calculator and use the units implied by the Dilution formula. If a value is unknown, choose a calculator that solves for that specific variable.
How accurate is the Dilution Calculator?+
The dilution estimate is accurate when stock concentration, target concentration, and final volume use compatible units. It assumes the C1V1 = C2V2 setup fits the solution and does not replace lab protocol or safety checks.
What should I check before using the Dilution Calculator result?+
Check that stock and target concentration use the same unit, and that final volume means the total solution volume after adding diluent. Follow lab safety and protocol requirements before preparing real solutions.
