Apera Instruments AI1104 pH Calibration Buffer Solution Kit 4.54 L (16 oz x 3) | NIST Traceable Accuracy +/- 0.01 pH

• Reported values are accurate to +/- 0.01 pH at 25 °C and are traceable to NIST Standard Reference Materials (SRMs).
• Produced in an ISO 9001:2015 certified facility using high-purity reagents, deionized water and certified analytical balances in a temperature controlled environment.
• color-coded for quick identification.
• Apera CalPod solution holder is included for organizing all the buffers and streamlining your calibration process.
• Double-sealed. 2-year expiration from manufacture for an unopened bottle.

• Prepare Buffer Solutions — Pour a small amount of each pH buffer (4.00, 7.00, 10.01) into separate clean containers. Use the included CalPod holder to keep them organized and prevent spills.
• Rinse Electrode — Thoroughly rinse the pH electrode with deionized water to remove any residual solution or contaminants before immersing it in the buffer.
• Calibrate pH Meter — Immerse the rinsed electrode into the first buffer solution (typically pH 7.00). Allow the reading to stabilize, then follow your meter's manual to calibrate. Repeat with other buffer solutions as required.
• Store Electrode — After calibration, rinse the electrode again with deionized water. Store it in the 3M KCL soaking solution to keep the glass membrane hydrated and ready for the next use.
