Hanna HI5124 pH 12.45 25°C Technical 500 mL

Hanna HI5124 pH 12.45 25°C Technical 500 mL

The Hanna HI5124 pH 12.45 25°C Technical 500 mL is a high-quality technical buffer solution with a certified pH value of 12.45 at 25°C, specifically designed for the calibration of pH meters used in strongly alkaline environments. Because of its accuracy and stability, it is widely trusted in laboratories and industrial applications where high-pH conditions are routinely encountered.

Importantly, the solution is NIST-traceable and is supplied with a Certificate of Analysis, ensuring both traceability and compliance with international standards.

Features

• Certified pH 12.45 at 25°C
  This buffer is ideal for applications that require accurate and consistent calibration in high-alkaline conditions. Therefore, it is frequently used in industries where elevated pH levels are critical.

• Traceable to NIST Standards
  Since it is prepared in accordance with National Institute of Standards and Technology (NIST) protocols, the solution ensures reliable and globally recognized accuracy.

• Certificate of Analysis Provided
  Additionally, each bottle includes a Certificate of Analysis, along with a batch number, expiry date, and a temperature-pH correlation table. This makes it easy to maintain documentation and meet audit requirements.

• Tamper-Proof and Airtight Packaging
  In order to preserve the pH value, the buffer is sealed in an airtight, tamper-evident bottle that protects it from atmospheric CO₂, which could otherwise alter its composition.

• Ready-to-Use Formula
  Moreover, the solution comes pre-mixed and standardized, which means it’s ready to use straight from the bottle—no dilution or preparation required.

• Multiple Volume Options Available
  For added convenience, Hanna offers buffer solutions in various formats: 20 mL sachets, 500 mL bottles, 1 Litre, and 1 Gallon (3.78 L). This allows users to select the volume that best fits their usage needs.

Applications

Due to its highly alkaline nature, the HI5124 buffer solution is well-suited for a variety of applications, including:

• Water Treatment Plants – Used to calibrate pH meters monitoring alkaline water and effluent.

• Food and Beverage Production – Ensures accurate pH control in cleaning and processing operations where high alkalinity is common.

• Hydroponic and Greenhouse Systems – Helps calibrate instruments monitoring nutrient solutions with elevated pH levels.

• Aquaculture and Aquatics – Provides stability in pH readings for aquatic systems requiring basic water conditions.

• Medical and Pharmaceutical Testing – Facilitates consistent readings in chemical and biological tests performed in alkaline environments.

• Industrial Chemical Processing – Ideal for calibration in production lines that involve caustic solutions or chemical reactions.

Best Practices

To maintain peak performance:

• Always use fresh solution—never reuse or pour used buffer back into the original container.

• Clean your electrodes thoroughly using Hanna’s dedicated cleaning solution before every calibration session.

• Store properly at a constant temperature of 25°C, away from direct sunlight and moisture.

• Check the label for expiration date and batch number to ensure traceability and compliance.

• Calibrate regularly, especially in demanding environments, to maintain accurate and repeatable results
