Use the new Wireless Drop Counter for more efficient and accurate titration data. Conducting a titration has never been easier!
- 1x Wireless Drop Counter
- 1x Micro Stir Bar
- 1x Drop Dispenser with Stopcock
- 1x Plastic Dispenser Rod Clamp
See the Buying Guide for this item's required, recommended, and additional accessories.
Product Summary
The Wireless Drop Counter has a wider (18 x 13 mm) drop window for better drop detection and easier alignment with burettes. It works equally well with large or small, fast or slow drops.
Measures up to 10 drops per second with drops as small as 0.5 mm.
Teaching Advantage
- IR filter assures accurate counts because room lighting cannot affect results
- Sensor unit can suspend up to three other probes in solution, simplifying many experiments
- Wider drop window (18x13mm) means better drop detection and easier alignment with burettes

Experiment Library
Perform the following experiments and more with the Wireless Drop Counter.
Visit PASCO's Experiment Library to view more activities.
How Hard is Your Tap Water?
Students use conductometric titration and gravimetry to determine how much calcium carbonate is in a sample of tap water.
How Much Acid is in Your Fruit Juice?
Students use titration and a pH sensor to study the organic acid content of fruit juices.
Double Replacement Reactions
In this lab, students will complete a titration to determine the amount of chloride ion in water samples.
Shape Of Titration Curves
Students use a pH Sensor and drop counter to determine the fundamental shape of a titration curve and the parameters that can cause it to change.
Measuring Vitamin C - Redox Titration
In this lab, students use an oxidation reduction potential probe to expand their understanding of titrations, carry out a redox titration, and then use the redox titration method to answer a question of their own design.
Stoichiometry in Solutions
Students use conductometric titration and particle modeling to study the stoichiometry of acid-base titration.
