Each row includes 10% excess for 3 replicate wells.

⚠ At least one dose needs <1 µL stock per well-equivalent. Use an intermediate working stock to reduce pipetting error.

WHAT IT DOES

From formula to a bench-ready decision.

Build a plate-ready set of treatment master mixes without calculating every concentration separately.

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

BUILT-IN CHECKS

What Tossora Lab checks.

  • Scales each dose for replicate wells and overage.
  • Flags tiny stock transfers.
  • Checks solvent exposure at every treatment concentration.
BENCH NOTES

Before you use the result.

  • Prepare one homogeneous master mix per dose before dispensing to replicate wells.
  • Keep vehicle exposure consistent across groups when your protocol requires it.

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

COMMON USES

When this calculator is useful.

  • Planning several drug concentrations for a dose-response experiment.
  • Scaling each concentration across replicate wells plus dead-volume overage.
  • Checking vehicle exposure before a treatment plate is prepared.
WORKED CONTEXT

Example: one stock, five treatment concentrations

Enter the drug stock once, list the target concentrations, then set volume per well, replicates and excess. Tossora Lab returns a separate stock-plus-medium recipe for each dose and displays the resulting stock-solvent percentage.

FAQ

Questions researchers often ask.

Should every treatment group have the same vehicle concentration?

Many experimental designs use a matched vehicle control, but the required approach depends on the protocol. Use the displayed solvent carryover to review the planned exposure.

What does extra volume do?

It scales each master mix above the exact well requirement to account for routine handling and pipetting loss.
