Yes, we have a drop counter! The Vernier Drop Counter accurately records the number of drops of titrant added during a titration. The software can record volume in drops or mL, and can simultaneously record pH (pH sensor sold seperately). The Drop Counter can also be used for conductometric or potentiometric titrations. It comes with its own reagent reservoir, or you can use your own buret.
