FAQs

1) What does this calculator actually reduce?

It reduces solution concentration by planning a dilution from a stronger stock to a weaker target. It does not model reaction kinetics, decomposition, or redox balancing.

2) Can I use different concentration units?

Yes. The form converts M, mM, µM, and nM into a common internal basis. This lets you mix stock and target units safely before calculating the required dilution volumes.

3) Why must stock concentration exceed target concentration?

A reduction workflow means you are diluting a stronger stock into a weaker target. If the target is stronger, you need concentration or evaporation, not simple dilution.

4) What does dilution factor mean?

Dilution factor shows how many times the stock is stronger than the target. A factor of 4 means one volume of stock becomes four final volumes after adding diluent.

5) Why add waste allowance?

Waste allowance helps cover transfer losses, dead volume, priming, and handling errors. It is useful when you need reliable final yield after dispensing into tubes, wells, or vessels.

6) What does aliquot rounding step do?

It rounds the stock volume upward to a convenient measurement increment. This is helpful when your pipette, dispenser, or graduated cylinder works best with fixed practical steps.

7) Does this calculator assume ideal volume behavior?

Yes. It assumes simple additive volume behavior during dilution planning. Highly concentrated, reactive, or temperature-sensitive systems may require lab-specific correction methods and validation.

8) Can I use it for buffers, salts, and reagents?

Yes, when the task is straightforward dilution from a known stock concentration to a lower target concentration. Confirm chemical compatibility, stability, and safety before preparation.
