Featured Equipment

pH Storage Solution

pH Storage Solution

A 500 mL bottle of storage solution for PASCO pH Electrodes.

pH Buffer Capsule Kit

pH Buffer Capsule Kit

Use this kit to create fresh solutions of known pH values (4, 7 & 10) for calibrating pH meters or other purposes.

pH Sensor

Wireless pH Sensor

Here’s the best tool for measuring pH since litmus paper. The Wireless pH Sensor connects via Bluetooth® to monitor the pH of solutions.

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
