Hanna HI5074 pH 7.41 25°C Technical 500 mL

The Hanna HI5074 pH 7.41 25°C Technical 500 mL is a premium-quality technical buffer solution with a certified pH value of 7.41 at 25°C. It is NIST-traceable and includes a Certificate of Analysis, making it suitable for laboratories and industries requiring reliable calibration near the neutral to alkaline range. This solution is especially useful in applications such as water treatment, aquaculture, hydroponics, and medical testing.

Features

• Accurate pH 7.41 Calibration
  With a stable value at 25°C, this buffer is ideal for calibrating pH meters used in environments where pH levels are expected to be slightly alkaline.

• Traceable to NIST Standards
  As part of Hanna’s technical buffer range, HI5074 is prepared under strict conditions in accordance with National Institute of Standards and Technology (NIST) guidelines. Therefore, it ensures consistent accuracy across different measurement systems.

• Certificate of Analysis Included
  Each bottle comes with a detailed certificate showing batch number, expiration date, and a pH-temperature correlation table. This allows users to maintain compliance and calibration traceability with ease.

• Secure and Tamper-Proof Packaging
  Furthermore, the airtight seal prevents CO₂ contamination, which can alter pH values over time, ensuring lasting solution stability.

• Various Packaging Sizes Available
  In addition to the 500 mL bottle, this solution is also offered in 20 mL sachets, 1 Litre, and 1 Gallon (3.78 L) containers. Consequently, users can choose the most suitable volume based on their calibration needs.

Applications

Thanks to its near-neutral pH, HI5074 is widely applicable in:

• Water Purification Systems – Ensures that pH meters used in water monitoring remain accurately calibrated.

• Food and Beverage Industry – Ideal for calibrating instruments during food quality control, where slightly alkaline levels may be encountered.

• Aquaculture and Aquatics – Reliable for adjusting and maintaining the pH of aquatic systems, promoting healthy environments for fish and plants.

• Hydroponics and Greenhouse Management – Accurate calibration supports precise nutrient delivery and pH control.

• Medical and Clinical Labs – Supports routine calibration of sensitive pH sensors in diagnostic and research settings.

Best Practices

To ensure optimal results:

• Always use fresh buffer during each calibration session. Reusing solution may introduce contaminants that alter its value.

• Clean your electrode with a Hanna general-purpose cleaning solution before use, as this promotes accuracy and prolongs electrode life.

• Store the solution properly at 25°C, keeping it sealed and protected from light and heat.

• Avoid returning used buffer to the original container, as this may compromise the integrity of the solution.
