Dilution Calculator

From formula to a bench-ready decision.

Turn a stock concentration and target concentration into the exact stock and diluent volumes to prepare.

Tossora Lab keeps units, intermediate values, and practical preparation checks visible so a mathematically correct answer is easier to translate into an experimental workflow.

What Tossora Lab checks.

• Stock concentration must exceed the target concentration.
• Sub-1 µL transfers are flagged as impractical.
• Stock-solvent carryover can be checked against a user-defined limit.

Before you use the result.

• Use an intermediate stock when the calculated transfer is too small for reliable pipetting.
• Prepare to final volume rather than assuming the diluent volume equals the final volume.

Research use only. Verify critical calculations, reagent specifications, route or instrument limits, and procedures against your approved protocol and institutional requirements.
