Description
Buffer solution pH 6,86 is a standard-quality reagent for pH calibration, providing a near-neutral reference point with an accuracy of ±0,01 pH. Each pack contains 25 single-use sachets of 20 ml, allowing laboratories to open only the volume required for a given calibration and thereby limit contamination and waste. The stated value of pH 6,86 is widely used in two- or multi-point calibration sequences alongside acidic and alkaline buffers. A certificate of analysis accompanies the product, and traceability is established to NIST standards for quality documentation and method support. This buffer from manufacturer Hanna Instruments is intended for routine verification of pH electrodes and meters in analytical chemistry, environmental testing and industrial quality control. The sealed sachet format preserves integrity until the moment of use and simplifies both bench-top and field calibration work. Net weight is 0,66 kg and gross weight is 1,66 kg. Country of origin is Romania. These features make the solution a practical, documented choice wherever a ready-to-use pH 6,86 standard is needed.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about 6.86 pH Value @25°C, (25) 20 mL sachet with Certificate of Analysis
What is this article?
6.86 pH Value @25°C, (25) 20 mL sachet with Certificate of Analysis 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.
