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 two 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
- 1x Drop Dispenser with Stopcock
- 1x Plastic Dispenser Rod Clamp

Advanced Placement • College / Chemistry
Students use titration and a pH sensor to study the organic acid content of fruit juices.
Advanced Placement / Chemistry
In this lab, students will use a drop counter and pH sensor to titrate monoprotic and polyprotic weak acids. Then they'll determine the relationship between the shapes of the curves and Ka.
Advanced Placement • College / Chemistry
Students use conductometric titration and gravimetry to determine how much calcium carbonate is in a sample of tap water.
High School / Chemistry • STEM
Students will be using a pH sensor, a drop counter, and Blockly coding to demonstrate the endpoint of a titration of an acid by a base.
Advanced Placement • College / Chemistry
Students compare the pH titration profiles of strong, weak and polyprotic acids.
Advanced Placement / Chemistry
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.
