Description
Technical buffer solution pH 6,86 is a ready-to-use calibration standard supplied as 25 individual sachets of 20 ml each. Intended for pH meter and electrode calibration, it offers a stated accuracy of ±0,01 pH at 25 °C and is supplied with a certificate of analysis. The single-use sachet format helps maintain solution integrity until the moment of use and supports convenient, contamination-controlled calibration routines in laboratory and process environments. Traceability is referenced to NIST standards. This technical-quality buffer from manufacturer Hanna Instruments is suited to routine quality control, educational work and general laboratory calibration where a reliable near-neutral reference point is required. Each sachet delivers a defined 20 ml volume, simplifying preparation of fresh calibration aliquots without bulk handling. The pack of 25 pieces provides an economical stock for frequent calibration cycles while keeping unused portions sealed. Net weight of the unit is 0,63 kg. Use according to standard pH calibration practice for meters and sensors requiring a 6,86 buffer point.
This article belongs on pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about 6.86 pH Value @25°C, (25) 20 mL sachets
What is this article?
6.86 pH Value @25°C, (25) 20 mL sachets 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 Produits chimiques de laboratoire et industriels.
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.
