Description
Buffer solutions pH 7,01 and 10,01 are standard-quality reagents prepared for routine pH electrode calibration. The set comprises five sealed 20 ml sachets for each stated pH value, delivering ten single-use portions in total and matching a pack size of 10 pc(s). Each buffer is specified to an accuracy of ±0,01 pH, enabling precise one- or two-point calibration of portable and benchtop meters. Traceability is established to NIST, supporting documented measurement chains in laboratory and field work. The individual sachet format keeps each aliquot protected until opened, limiting contamination and evaporation that can affect open bottles during repeated use. These calibration buffers from manufacturer Hanna Instruments are suited to quality control, process monitoring, teaching laboratories and general analytical practice wherever reliable pH adjustment of measuring systems is required. Net weight is 0,266 kg and gross weight 1,266 kg. With five fresh 20 ml portions available for pH 7,01 and five for pH 10,01, the pack supports frequent electrode checks while maintaining consistent buffer performance across successive calibration sequences.
This article belongs on pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
10.01 & 7.01 pH Value @25°C, (10) sachets, 5 each is the article on this page. Luminix Health distributes Hanna Instruments for laboratory use. It sits in pH buffers & conductivity standards, inside Buffers & pH solutions, in Lab chemicals.
A pH buffer for calibration has a stated pH at a stated temperature, often traceable. A conductivity standard has a stated conductivity. They are not general reagents and they should not be poured back into the bottle. The temperature of the measurement has to be the temperature on the label, or the meter has to compensate.
A buffer resists a change in pH when a little acid or base is added. It does that because a weak acid and its conjugate base are both present. A pH buffer used to calibrate a meter has a stated value at a stated temperature. A biological buffer such as Tris or HEPES is chosen because it holds the pH of a living system and does not poison it. Conductivity standards are the sister articles for a conductivity meter. The ions are on PubChem. Electrode calibration practice sits with EURAMET and BELAC.
