The pH 7.01 buffer solution in quick and easy to use 20mL sachets is one of the most commonly used buffer solutions. 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. Latest Hanna portable and bench microprocessor instruments are calibrated with pH 7.01.

The single dose sachets are really handy with each sealed sachet holding just the right amount of solution. Each time a meter or electrode is calibrated using the Hanna sachets, it is like using a newly opened bottle of solution!

Hanna 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, an expiry date, and the correlation table between pH and temperature. A certificate of analysis is available on request. 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.

• Ideal for users who do not calibrate frequently
• Ideal for field use due to portability
• Every sachet is as fresh as the day it was packaged
• Light block packaging prevents oxidation from UV light that could alter the buffer value
• Should be stored at 25°C, away from direct sunlight for accurate readings
