Description
pH buffer solution pH 12,65 ± 0,01 is a ready-to-use calibration standard supplied in a practical 500 ml Twin-Neck dosing bottle with a separate compartment. This design removes the need for a second vessel during calibration and helps preserve the purity of the buffer throughout use. The solution is coloured to reduce the risk of mix-ups between different buffer values in busy laboratory workflows. Traceable SRM certificates according to NIST support documented quality control, while a pH/temperature dependence table printed on the label assists accurate readings under varying conditions. After opening, the buffer is intended for consumption within 12 to 15 months. With a net weight of 0,600 kg and a 500 ml fill volume, the pack suits routine electrode calibration in analytical and quality-control laboratories. This LABKEM buffer from manufacturer Labbox is formulated for reliable pH meter adjustment where a high alkaline reference point is required.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about pH Buffer solution with measuring chamber, pH 12,65 ± 0,01, 500 ml
What is this article?
pH Buffer solution with measuring chamber, pH 12,65 ± 0,01, 500 ml is the article on this page. Luminix Health distributes Labbox 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.
