Temperature mixing formula

This page is to help calculating the amount of one liquid you need to add to another to get a special temperature. This is often usefull if you perform a temperature shift for example with cultures of organisms that carry a temperature sensitive mutant.

Here is a form of Richmann’s calorimetric mixing formula:

[math]\displaystyle{ m_{1}= \frac{m_{2}\cdot T_{2}+ T_{m}\cdot m_{2}}{T_{m}-T_{1}} }[/math]
