How this works
Scaling a recipe just multiplies every component's amount by the same factor, which keeps every ratio (monomer to initiator, catalyst to ligand, concentration) exactly the same as the original. Enter each component from your recipe below, set a scale factor directly or derive one from a current and target batch size, and copy the scaled amounts back into your notebook.

Before you scale up
- Heat transfer changes with scale. A larger batch has a smaller surface area to volume ratio, so exotherms (radical initiation, fast catalyst turnover) dissipate heat more slowly. A recipe that runs isothermally at 1 mL scale can run away at 100 mL scale.
- Mixing and degassing take longer. Stir efficiency, freeze pump thaw cycle time, and sparge time all need to scale with volume, not stay fixed.
- Concentration, not just amount, controls kinetics. This tool keeps every ratio and concentration identical by design; if you also change solvent volume independently, recheck your target concentration.
- Reagent grade and purity matter more at scale. Trace inhibitor, water, or oxygen that's negligible in a small aliquot can meaningfully shift results in a larger, longer running batch.
