Apera Instruments AI1115 pH Calibration Buffer Solution Kit 7.00, 4.00, 10.01 | NIST Traceable

• 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.
• Double-sealed. 2-year expiration from manufacture for an unopened bottle.

• Carefully open the required pH buffer bottle (e.g., pH 7.00). Pour a small, sufficient amount into a clean beaker, ensuring not to contaminate the remaining solution in the bottle. Reseal the bottle immediately. — Prepare Solutions
• Immerse the clean pH electrode into the buffer solution. Follow your specific pH meter's manual for the calibration sequence, typically involving rinsing and stabilization steps between different buffer solutions. — Calibrate pH Meter
• After calibration with each buffer, rinse the pH electrode thoroughly with deionized water. Store the electrode properly according to its instructions. Tightly reseal all buffer solution bottles and store them in a cool, dry place. — Rinse and Store
