Free Lab Calculators: Solution Prep, Dilution, PCR Mix
Lab calculators that work the moment you open them, no account or login needed. Each one shows the formula, converts units for you and includes bench tips so you can follow the result directly.
- Antibody Dilution Calculator (1:N)
How to make 1:500 or 1:1000: stock volume in μL and diluent to top up.
Stock (μL) = Total (mL) × 1000 ÷ N
- Solution Preparation Calculator (% w/v)
Grams to weigh and volume to top up for 5% BSA, 0.9% NaCl and other % w/v solutions.
Solute (g) = Conc. (%) × Volume (mL) ÷ 100
- PCR / qPCR Reaction Mix Calculator (Master Mix)
Total mix and master mix volume for N reactions, with 10% pipetting overage built in.
Total (μL) = Rxn vol × N × 1.1
You got this step right, but a whole experiment has dozens of linked parameters. Change one dilution factor and everything downstream has to be recalculated. In Vara the parameters of your whole experiment are connected, so changing one recalculates the rest automatically. Manage 3 experiments for free.
