Hanna pH 9.18 Calibration Solution (1 L)/water testing HI7009U/1L

pH 9.18 Calibration Solution (1 L) is a ready-to-use buffer solution formulated for calibration of pH meters and electrodes at the alkaline end of the pH scale. The solution provides a stable pH 9.18 reference and is intended for laboratory and field calibration of pH instruments where an accurate high‑pH standard is required. The bottle label includes a temperature chart of the actual pH value at various temperatures to support temperature‑dependent calibration adjustments.

Key Features:

• pH value: 9.18
• Volume: 1 L
• Accuracy: ±0.01 pH @ 25°C
• Manufactured in accordance with ISO 3696 / BS3978
• Traceability: values traceable to NIST Standard Reference Materials (SRMs)
• Air‑tight bottle with tamper‑proof seal; lot number and expiration date printed on label
• Unopened expiration: 5 years from date of manufacture

Advantages:

• Provides a precise high‑pH reference (9.18) with ±0.01 pH accuracy for reliable instrument calibration.
• Traceability to NIST SRMs and ISO/BS production standards support reproducible, documented calibrations.
• Color‑coded label and printed temperature chart simplify buffer identification and temperature‑compensated calibration.
• Air‑tight, tamper‑proof packaging with lot number and expiration date helps ensure solution integrity and freshness.
