Buffer Calculator

Description

Buffer Calculator is an online tool for the design and preparation of thermodynamically corrected buffers. The tool makes corrections for the temperature at which the buffer will be used, makes Debye-Huckel corrections for the effect of ionic strength on pKa, and describes two ways (titration or by accurate weight) for preparation of the recipe. Select from 36 varying pKa buffering agents. Choose the buffer species you want to use, and enter parameters for volume, pH, and concentration of buffer species. Then, include the option to modify the ionic strength by addition of neutral salt. Finally, enter the temperature at which you'll use the buffer, and the temperature at which you'll make it up (these are often not the same). The 'Recipe’ button will then open a new window with a recipe, that you can print, or if you wish, copy the information to a lab notebook.

Buffer Calculator Oval 17

Rob,

When I suggested Buffer Calculator for LabWorm, I was unaware that the web site link I posted contained an unsanctioned rehash of your ms code.

Sorry!

Gary

Gary, No problem - I understand that this was in good faith. What bothered me the most is that the calculator is no longer maintained..the site looks dead to me, and the mailbox is full (always a warning sign). A link to the Liverpool site points to a maintained version. Best, Rob

All good Oval 17

Thanks for acting promptly.
Everything in order now. It's a nice resource/idea you have here.

Cheeky buggers! Oval 17

Why not advocate and link to original source, my website, rather than an unsanctioned rehash of my ms code. Unimpressed!
