Chemistry

Convert plane intercepts on a, b, and c into Miller indices with steps, parallel-axis handling, and negative-index formats.

Calculate hydraulic retention time from tank volume and flow rate, with unit conversion and an optional effective volume adjustment.

Calculate detention time, flow rate, or tank volume using known volume or tank dimensions with built-in unit conversion.

Find edge length, atomic radius, volume, density, and packing factor for SC, BCC, and FCC cubic unit cells.

Solve the Beer-Lambert law for absorbance, concentration, molar absorptivity, or path length from absorbance or transmittance.

Calculate resuspension volume, concentration, or amount for reagents and oligos with unit conversion and bench-friendly warnings.

Estimate protein solubility tendency from pH, pI, salt, and temperature with a clear score and pH = pI baseline comparison.

Solve for v, Vmax, Km, or [S] with optional kcat and kcat/Km outputs, plus plain-language checks for half Vmax and unit matching.

Estimate pI for an amino acid or sequence, then check net charge at your chosen pH with clear assumptions and pKa options.

Convert assay data to enzyme activity, U/mL, specific activity, kat, and nkat using product or absorbance data.
