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
What's Included
- 1x Wireless Drop Counter
- 1x Micro Stir Bar

Experiment Library
Perform the following experiments and more with the Wireless Drop Counter.
Visit PASCO's Experiment Library to view more activities.
Percentage of H₂O₂ in Your Drugstore Hydrogen Peroxide
This lab is an introduction to Redox titration. Students use a redox probe and titration to determine the hydrogen peroxide content of a drugstore formulation.
How Much Acid is in Your Fruit Juice?
Students use titration and a pH sensor to study the organic acid content of fruit juices.
Titration Curves
Students will use a pH sensor and a drop counter to explore the shape of a titration curve produced by a strong acid and a weak acid when titrated by a strong base.
Evaluation of Lemonade as a Buffer
Students use a powdered commercial lemonade formulation as a model for buffers and test its capacity to resist pH changes.
Stoichiometry in Solutions
Students use conductometric titration and particle modeling to study the stoichiometry of acid-base titration.
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.
