How can I improve my results with the Drop Counter?

The keys to acheiving good data are:
-deliver the drops no faster than 1 drop/s
-titrate a small amount of solution, about 5 mL
-use a magnetic stirrer and stirring bar or Microstirrer
-Make sure the reaction mixture is well-stirred. If you're using a Vernier Microstirrer, stir the mixture at a very high speed. If you're using a conventional magnetic stirring bar, stir the mixture at a speed that creates a small vortex.
