iPad, iPhone, Android
Offering tools beyond the standard molarity or dilution calculators, the Promega Biomath Calculators app offers a total of thirteen calculators for the life scientist. The calculators are divided into DNA conversions (such as converting mass to moles, or calculating the nanograms of DNA insert required for a ligation), protein conversions (such as calculating protein size from a given length of coding DNA), and “other” calculators that include classics like molarity and dilution calculators, as well as a temperature converter and a tool to calculate the melting temperature of DNA oligos. A nice feature of this app that isn’t present in many other calculator apps is the inclusion of the actual formulas used for each of the calculations.
