Biology
Chlorophyll Concentration Calculator
Converts spectrophotometer absorbance readings at 645 nm and 663 nm into total chlorophyll concentration in a plant extract. Use it in plant physiology and ecology labs to assess photosynthetic pigment content.

Biology
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.
