Buffers vs Bunny Counter

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!

- Do you need to count without taking your eyes from counted things? How many bunnies crossed the road? How many cells on the glass counter? How many colonies on the Petri dish? Just tap on the screen and the your count goes up. - Do you want to know 0-60 mph of your car? Do you need to measure time of the event that happens quickly, so you measure the time without taking eyes from the event? Car takes off and you press on the screen. Car reaches 60 mph and you take your finger from the screen. Bunny appears from the forest and you press the screen, you release screen when bunny disappears in the forest: people argue for how long they saw bunny - 3 seconds, 5 seconds, but you look at the Rapid counter and know exact time bunny was there with precision up to 0.01 of second.
