Lab Tools
In-vitro molarity & dilution calculator.
Plan stock and assay solutions for the bench: convert between mass, molar concentration and volume, and work out serial dilutions. For laboratory research use — no dosing or administration math.
⚗️In-vitro lab tool. For preparing research solutions on the bench only. This is not dosing, medical, or administration guidance — products are for laboratory research use only.
How strong is my solution?
Dissolve a powder in solvent to find the concentration — or work backwards. Pick what you want to find:
Dilute a stock solution
You have a strong stock and want a weaker working solution. Enter three values and we'll tell you how much stock and how much solvent to combine. C₁V₁ = C₂V₂
stocksolvent
Enter your stock strength, target strength, and final volume.
Research use only. This calculator performs standard in-vitro stock-solution and dilution chemistry for qualified researchers. It does not provide dosing, reconstitution-for-administration, or any human-use guidance, and nothing here is intended to diagnose, treat, cure or prevent any condition.
