Chemical/biochemical pocket companion designed by the editors of Current Protocols. Choose from a list of all of the commonly used biological buffer systems, enter your desired volume, pH, and buffer concentration, as well as the concentrations of your stock solutions of the conjugate acid and base, and the calculator will inform you of the exact volumes of these stock solutions to mix in order to obtain the buffer needed.

Helpful for making buffer solutions

Current Protocols have done a nice job implementing an iPhone app to prepare common buffers.

An option to export or somehow document the information for a given buffer calculation would be a big plus.

Cool App

Great for common buffers. If y'all update can you add the ability for a custom buffer (pKa). That way us xtal growers can use it with our strange buffers.

Not sure what i was expecting. Perhaps a lengthy list of buffers. I didn't get that. Perhaps some magical app that will let me know, based on pka values how to drive the reaction to a certain pH. Meh. Either way, i think the app is useless as this calculations are easily done by your own brain. If they aren't, you may need to exercise that ability and therefore avoid this app.
