BenchCalc
Calculators biologists actually use at the bench.
No login. No ads. Just quick calculations.
Peptide Molecular Weight
Calculate MW from amino acid sequence. Supports FASTA, modifications, and μg/nmol conversion.
Dilution Calculator
Calculate volumes for dilutions and mixing. C₁V₁ = C₂V₂ with pipette-friendly rounding.
Molarity Calculator
Calculate mass, volume, and molarity for solution preparation. Includes common MW reference.
Mixing Calculator Coming Soon
Calculate mixing ratios by weight. Useful for buffer preparation and reagent mixing.
FACS Cell Number Coming Soon
Calculate cell numbers and volumes for flow cytometry experiments.
