Biology

Population Growth Rate Calculator

Compute the exponential growth rate r from initial and final population sizes over a time interval, as r = ln(N_final / N_initial) / t. Useful for bacterial cultures, microbial fermentation, cell-culture monitoring, and any closed system in exponential phase.

PCR Efficiency Calculator

Compute the amplification efficiency of a qPCR reaction from the slope of a standard curve fitting Cq values against the log of template concentration. A slope of βˆ’3.32 yields 100% efficiency (true doubling per cycle).
