Free lab calculators
Bench arithmetic, with no account and nothing stored. These are the same calculators Cyzica runs inside an experiment record — here they just run on their own.
Solutions
- Dilution (C₁V₁ = C₂V₂)How much stock to take and how much diluent to add.
- Serial dilutionTransfer and diluent volumes for a series at a fixed fold per step.
- Molarity to massHow much powder to weigh out for a molar solution.
- Percent solution (w/v)Grams per 100 mL, at whatever final volume you need.
- Scale a recipeTake a buffer recipe to a different final volume.
Bench work
Centrifuge
Animal work
Every one of these works here without an account. What Cyzica adds is that the answer stops being something you copy into a notebook: a calculator runs inside an experiment record, and the numbers it produced are kept with the record. See what it does.
