Apera Instruments AI1114 pH Calibration Solution Kit 4.00 & 7.00 pH, 473ml (16 oz) Each | NIST Traceable Lab Grade

• 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 for Calibration — Ensure your pH meter is clean and the probe is rinsed with distilled or deionized water. Have the Apera Instruments AI1114 pH Calibration Solution Kit bottles and the included CalPod holder ready on a clean, stable surface.
• Calibrate with pH 7.00 — Open the pH 7.00 buffer solution bottle. Pour a sufficient amount into the CalPod holder or a clean beaker. Immerse the pH probe into the solution, ensuring the sensor is fully covered. Follow your pH meter's instructions to initiate the calibration process for the first buffer.
• Calibrate with pH 4.00 — After the meter stabilizes and confirms calibration with pH 7.00, rinse the probe again. Open the pH 4.00 buffer solution bottle and pour a sufficient amount into the CalPod holder or a separate clean beaker. Immerse the probe and complete the calibration for the second buffer.
• Finalize and Store — Once calibration is complete, rinse the pH probe thoroughly. Securely recap both buffer solution bottles and store them upright in a cool, dry place. Clean the CalPod holder and store it with the solutions. Ensure bottles are double-sealed for maximum shelf life.
