Description
pH buffer solution in a dosing bottle, pH 7,00 ± 0,01, is a ready-to-use laboratory calibration standard supplied as a 500 ml pack in a Twin-Neck dosing bottle with a separate compartment. This bottle concept removes the need for a second vessel during calibration and helps keep the buffer free from contamination between uses. The solution is coloured to reduce the chance of mix-ups with other standards on the bench. Traceable SRM certificates according to NIST support documented quality control, and the label carries a table of pH values versus temperature for quick reference during measurement. After opening, the buffer is intended for use within 12 to 15 months. From manufacturer Labbox (LABKEM product type), this preparation suits routine pH meter and electrode calibration in analytical, quality-control and teaching laboratories. Net weight is 0,600 kg. The Twin-Neck dosing format streamlines daily workflow while protecting solution integrity for reliable, repeatable calibration results.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about pH Buffer solution with measuring chamber, pH 7,00 ± 0,01, 500 ml
What is this article?
pH Buffer solution with measuring chamber, pH 7,00 ± 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.
