How do I make more pH electrode storage solution?
I need more storage solution for my PASCO pH electrodes.
Mix your own pH storage solution
Mix a solution consisting of equal parts 4M Potassium Chloride (KCl) and pH 4 buffer solution. KCl is a common salt which may be obtained from most chemical suppliers. You may store the pH electrode indefinitely in this solution, but for long term storage, we recommend storing the electrode dry. Please see KB 21: pH electrode maintenance for more details.
Purchase Storage Solution from PASCO
You can also purchase pH storage solution as pH storage solution SC-3507.
Has a wide measurement range of 0 to 14 ph. Has a resolution of 0.01 ph. For use with PASPORT Interfaces.
Allows students to measure Temperature, pH/ISE/ORP, Absolute Pressure & Voltage in one sensor. For use with PASPORT Interfaces. The replacement PS-2172 does not have a voltage sensor. The conductivity sensor on the advanced sensor is more broadly useful across chemistry.
The Advanced Chemistry Sensor measures pressure, temperature, pH, and conductivity.
This is a multipurpose sensor that incorporates probes for pH, conductivity, temperature, and optical dissolved oxygen.
Replacement pH electrode for PASCO pH Sensors.
Here’s the best tool for measuring pH since litmus paper. The Wireless pH Sensor connects via Bluetooth® to monitor the pH of solutions.
