Description
pH buffer solution pH 1,68 ± 0,01 is a ready-to-use acidic calibration standard presented in a 500 ml Twin-Neck dosing bottle with a separate compartment. This dosing format removes the need for a second vessel during calibration and helps preserve the purity of the remaining buffer. Coloured coding reduces the risk of mix-ups when several standards are used in sequence. A pH/temperature variation table on the label supports temperature-related corrections at the bench. Traceable SRM certificates according to NIST provide documented metrological traceability, supporting quality systems that require verifiable calibration materials. After opening, the solution is intended for use within 12 to 15 months. Supplied as a LABKEM product from manufacturer Labbox, this buffer has a volume of 500 ml and a net weight of 0,600 kg. It is well suited to routine pH meter and electrode calibration in analytical, quality-control and research laboratories wherever a defined low-pH reference of 1,68 ± 0,01 is required in a practical dosing bottle.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about pH Buffer solution with measuring chamber, pH 1,68 ± 0,01, 500 ml
What is this article?
pH Buffer solution with measuring chamber, pH 1,68 ± 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.
