Description
C 43 benzoic acid, NIST 39j is a high-purity benzoic acid powder supplied as a Standard Reference Material with an official certificate from the National Institute of Standards & Technology (NIST), USA. The 30 g packaging unit provides a practical quantity of certified reference grade material for laboratories that require traceable standards in analytical calibration, method validation and quality-control workflows. This finely prepared powder is especially suited to calorimetric work and other procedures where documented purity and composition data are essential. Available from manufacturer IKA, the C 43 reference material supports accurate, reproducible measurements in research and routine laboratory environments. Each unit is accompanied by the NIST certificate, giving users direct access to the certified values needed for reliable results. The 30 g pack balances everyday laboratory consumption with the need to preserve the integrity of the certified material across multiple uses, making it a dependable choice for bomb calorimetry and related thermal-analysis protocols.
This article belongs on pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about C 43, Benzoic acid, NIST 39j, 30 g
What is this article?
C 43, Benzoic acid, NIST 39j, 30 g is the article on this page. Luminix Health distributes IKA 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.
