Description
pH buffer solution 4,00 ± 0,01 is a ready-to-use laboratory calibration standard supplied in a 1000 ml pack for accurate pH meter adjustment and routine quality control. Colour-coded to help prevent mix-ups during daily work, this buffer supports reliable electrode calibration in analytical, research and industrial laboratories. Traceable SRM certificates according to NIST strengthen measurement confidence, and a certificate of analysis can be downloaded from the manufacturer website. The label includes a practical table of pH versus temperature variations so operators can account for working conditions during calibration. Offered as a LABKEM product from manufacturer Labbox, the solution is intended for use within 12 to 15 months after opening. With a net weight of 1,080 kg and a defined volume of 1000 ml, it fits standard bench and stockroom workflows where consistent buffer performance matters. Suitable for instrument checks, method validation and everyday calibration routines, this buffer helps laboratories maintain reproducible pH measurements with clear handling guidance on every bottle.
This article belongs on pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about pH Standard solution pH 4,00 ± 0,01, 1000 ml
What is this article?
pH Standard solution pH 4,00 ± 0,01, 1000 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.
