About Buffers
Buffers is a tool for designing buffer solutions for pH control. Buffers is useful both as a handy reference of available buffering agents and as an accurate, portable buffer calculator for chemical, biochemical and biological research.
With Buffers you can:
- Select from 42 commonly used buffering agents
- Generate accurate recipes covering broad pH, concentration and temperature ranges
- Access detailed information about each available buffer system
- E-mail, text, copy or print recipes
To use Buffers, just choose a buffering agent and target pH along with the desired solution volume, temperature and buffer concentration. The recipe is calculated with the push of a button. Buffers uses a sophisticated algorithm that is more versatile and potentially more accurate than simple calculations based on the Henderson-Hasselbalch equation.
An information page for each buffering agent lists the pKa, appropriate pH range, and temperature dependence, along with molecular weights and CAS numbers for the acid and base forms and other pertinent information.
Bring your buffer calculations into the lab where you need them!
