  • DNA Concentration Calculator

    DNA Concentration Calculator

    DNA Concentration

    Enter spectrophotometer values

    Formula:

    DNA Concentration
    DNA (μg/ml) = A260 × 50 × Dilution factor

    Note:
    1 A260 = 50 μg/ml for double-stranded DNA

  • RNA Concentration Calculator

    RNA Concentration Calculator

    RNA Concentration

    Enter spectrophotometer values

    Formula:

    RNA Concentration
    RNA (μg/ml) = A260 × 40 × Dilution factor

    Note:
    1 A260 = 40 μg/ml for RNA

  • DNA Purity Calculator

    DNA Purity Calculator

    DNA Purity (A260/A280)

    Enter absorbance values

    Formula:

    DNA Purity = A260 / A280

    Interpretation:
    ≈ 1.8 → Pure DNA
    < 1.8 → Protein contamination
    > 2.0 → RNA contamination
