HI-70007P – 25 x 20ml sachets pH 7.01 buffer solution

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!

Benefits of individual packaging

  • 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.

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

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.

For safety and traceability, all Hanna solutions are provided with a label showing the batch number and expiry date. A certificate of analysis is available on request in line with NIST standards.

Remember:

  • Calibration only counts when using fresh solutions and properly cleaned electrodes every time.
  • Routine maintenance will ensure accurate readings while extending the life of the electrode.

Useful information:

Hanna Colour Coding for 1L and 1 gallon bottles:

pH 4.01 - Red

pH 7.01 - Green

pH 10.01 – Violet

All calibration buffers are made to a premium quality, produced in accordance with ISO 3696/BS3978 standards using high purity salts, deionised water, certified weight-checked balances, and Class A glassware in a temperature controlled environment monitored with certified thermometers.

All bottles meet with FDA Standards (US Food and Drug Administration).

*Millesimal and Technical Buffer solutions explained

Designed and manufactured for those where accuracy really is vital, Millesimal buffer solutions are produced to a premium quality for customers who require a greater resolution of 0.001 for pH measurements. Accuracy can be guaranteed at +/- 0.002 @ 25 C.

To achieve the more accurate results, Millesimal Buffer solutions are available in pH1.000, pH1.679, pH2.000, pH3.000, pH4.010, pH6.000, pH6.862, pH7.010, pH8.000, pH10.010, pH11.000, pH12.000, pH12.450, pH13.000.

Both technical and Millesimal buffer solutions come with a certificate of analysis on purchase.
