Compare calculators

Both calculators run independently — change the inputs on either side to compare results.

Bacterial Generation Time Calculator

Determines how long bacteria take to double in number during exponential growth. Use it in microbiology labs to characterise growth kinetics, compare strains, or monitor antibiotic effects.

Primer Melting Temperature Calculator

Estimate the melting temperature (Tm) of a PCR primer from its GC content and length using the simplified Wallace-rule approximation. Useful for quickly designing and checking primers before running PCR.
