– Set a slow drop rate. For the best, most accurate data, we recommend setting the rate at 2 seconds per drop or slower. A slow rate provides enough time for each drop of titrant to be thoroughly mixed in the solution and the pH sensor (or other sensor) to respond.
\n– Minimize the volume of solution to be titrated. We recommend 5-10 mL of test solution. Larger volumes will take longer to mix and may require a very slow drop rate for best results.
\n– Use the Vernier Microstirrer. It helps deliver solution directly to the pH bulb, minimizing the response time. Also, you can run a magnetic stirrer at a very high speed and the Microstirrer will not form a visible vortex, preventing splashing.
\n– Add only as much distilled water to the solution being titrated as is necessary to cover the bulb of the pH Sensor (or other sensor).
\n– Use the plastic reagent reservoir that is supplied with the Drop Counter. The reagent reservoir provides a wider diameter and less change in the hydrostatic pressure per unit volume of titrant above the 2-way valve.
\n– Another advantage of using the plastic reagent reservoir is the pair of 2-way valves, using one for drop rate adjustment, and the other as an on-off valve. This eliminates the need to do a fine adjust during the initial readings, and also allows the user to set a consistent rate.
\n– If you want to allow for more thorough mixing when you are near the equivalence point, you can also manually release drops at a slower rate for that region of data.<\/p>","protected":false},"excerpt":{"rendered":"
