ChemBioCalc: Lab Calculator

ChemBioCalc is a lab calculator for chemistry, molecular biology and pharmacy. It puts 75+ lab tools in one app: molarity and molar mass, dilution (C1V1 = C2V2), buffer preparation, stoichiometry, titration, HPLC, PCR and qPCR, cell culture, ELISA, pharmacokinetics and method validation. Every tool shows the formula it uses, and the validation tools are referenced to ICH Q2(R2), EMA M10, USP 621 and ICH Q1E. FREE TOOLS - Molarity and solution calculator, concentration converter, molar mass - Dilution calculator (C1V1 = C2V2), CFU and serial dilution - Chemical equation balancer, stoichiometry, reaction yield, empirical formula - Titration simulator with a live pH curve, Ksp, gas laws, thermochemistry, electrolysis - HPLC mobile phase, HPLC gradient solvent volumes and system suitability - Dissolution similarity f1 and f2 (FDA 1997, EMA 2010) - DNA/RNA, PCR master mix and primer Tm, sequence tools, protein MW and pI - Cell culture: counting, viability and passage - Periodic table of 118 elements, scientific calculator, formula sheet, lab timer PRO TOOLS Analytical chemistry: buffer preparation (Henderson-Hasselbalch), standard curve and LOD/LOQ, method validation (ICH Q2(R2), EMA M10), measurement uncertainty, outlier tests, SPC and Gage R&R, HPLC column selector, HPLC method transfer (USP 621), HPLC sequence builder, GC, multi-component UV-Vis, IR/NMR/MS spectra, XRD, RGB colorimetry, adsorption isotherms, kinetics and thermodynamics, design of experiments (DoE and RSM), electrochemistry, Arrhenius. Molecular biology: qPCR (ddCt, standard curve, primer efficiency), primer designer, cloning and restriction map, plasmid map, CRISPR guide RNA, NGS coverage, protein suite, enzyme kinetics (Michaelis-Menten), ELISA 4-PL, western blot, electrophoresis, gel/TLC analysis, microbiology.
