The Hanna Instruments pH 7.01 buffer solution is supplied in a 500ml bottle. pH 7.01 is ideal for those requiring an accurate neutral reading, particularly those working in water purification plants, the food industry, aquatics, and Hydroponics, and wherever the pH is expected to be neutral. The Hanna Instruments buffer solutions are prepared, ready-to-use, according to precise formulas and standardised in accordance with the National Institute of Standards and Technology (NIST) to ensure quality and accuracy. All solutions show a batch number, expiry date, and the correlation table between pH and temperature. All bottled solutions are sealed with an air tight, tamper-proof seal to prevent any Carbon Dioxide from entering and causing a change in the pH buffer value.
