Tools for spectrophotometric measurements, protein quantitation, and standard curve analysis.
Solve A = εlc for absorbance, concentration, or path length.
Calculate protein concentration from UV absorbance at 280 nm.
Spectrophotometric measurements are among the most common quantitative techniques in any lab. These calculators handle the math behind absorbance-based concentration measurements, from the fundamental Beer-Lambert law to practical protein quantitation methods like A280 and Bradford assays.
