Calculators for buffers, molecular biology, protein work, and cell biology.
Calculate buffer pH from component concentrations and pKa.
Concentration and purity from A260 absorbance.
Scale PCR reactions to multiple tubes with overage.
Melting temperature by Wallace, salt-adjusted, and nearest-neighbor methods.
Concentration, viability, and seeding from hemocytometer counts.
Exact volumes for pouring Tris-glycine polyacrylamide gels.
Biology and biochemistry calculations span everything from buffer preparation and pH adjustment to PCR reaction setup and gel electrophoresis. These tools are designed for the bench scientist who needs quick, reliable answers without digging through protocol appendices.
