The HI7007-012 is a high-precision, NIST-traceable pH 7.01 calibration buffer crafted under stringent ISO conditions using ultra-pure components. Each 120 mL bottle is hermetically sealed and tamper-resistant, clearly displaying its lot number and expiration date for easy traceability. With an accuracy of ±0.02 pH at 25 °C and an included temperature compensation chart, this buffer ensures reliable calibration across temperature variations. Its color-coded, dye-free formula avoids staining electrodes and features a Certificate of Analysis for quality assurance. Unopened, the solution remains stable and effective for up to five years.
