Hanna's extended description

Technical Buffer Solutions are available in 500ml, 1 litre, 1 Gallon*, and handy 20ml sachets in packs of 10 or 25 for on-site or field use. The sachet single dose is safe, easy to carry and remains fresh.

Technical buffer solutions come with a certificate of analysis on purchase.

*One Gallon, colour-coded bottles are available in pH 4.01, pH7.01 and 10.01.


HI-5004 pH4.01 Technical Buffer Solution 500ml

HI-5004 is a premium quality pH 4.01 Technical buffer solution, National Institute of Standards and Technology (NIST) traceable and supplied with a Certificate of Analysis.

One of the most commonly used buffer solutions, it is extremely stable and represents the mid-way point in the acid range of the pH scale - ideal for those requiring an accurate acid reading, particularly those working in water purification plants, the food industry, and wherever the pH is expected to be acidic.

Buffer solutions should be stored at 25 C, away from direct sunlight for accurate readings.

To correctly maintain your meter/electrode, we highly recommend use of a Hanna cleaning solution, as well as a buffer, for maximum performance every time.

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. 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.
