Hanna HI60004-02 pH 4.010 25°C Millesimal

Hanna HI60004-02 pH 4.010 25°C Millesimal

The Hanna HI60004-02 pH 4.010 25°C Millesimal is a premium-quality pH 4.010 millesimal buffer solution, designed for precise calibration in the acidic range. It is NIST-traceable and comes with a Certificate of Analysis, ensuring both accuracy and reliability.

Features

Ideal for Acid-Range Calibration

This buffer is one of the most widely used standards, representing the mid-point in the acidic range of the pH scale. It is especially suitable for applications in water purification plants, the food industry, and any process requiring accurate acidic pH measurements.

Fresh Solution Every Time

Each box contains 25 single-dose sachets (20 mL each), individually sealed to maintain freshness and prevent contamination. As a result, every calibration is performed with a solution as fresh as the day it was packaged.

Light-Resistant Packaging

The light-block sachets protect the buffer from UV degradation, preventing oxidation and ensuring stability throughout its shelf life.

Traceability and Quality Assurance

Every sachet includes the batch number, expiry date, and a pH–temperature correlation table. The included Certificate of Analysis provides complete traceability and quality validation.
