Description
NIST/DIN Buffer pH 7.413 is a precision pH calibration buffer solution intended for accurate electrode calibration and verification in laboratory environments. With its defined pH value of 7.413, the buffer supports reliable measurements across analytical and quality-control workflows and is traceable to certified international SRM-NIST standards. Supplied in a practical 250 mL pack, it is well suited to routine pH-meter checks according to NIST and DIN requirements. The solution originates from manufacturer Mettler-Toledo OnLine and delivers consistent performance for research, industrial and pharmaceutical laboratories that demand standardised reference materials. Net weight is 0,25 kg and gross weight 0,286 kg, facilitating straightforward handling and storage on the bench. Ideal for applications in the neutral pH range, this buffer enables reproducible calibration procedures while maintaining full traceability to recognised international standards, thereby supporting compliance and measurement confidence in daily laboratory practice.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about NIST/DIN Buffer pH 7.413 250mL
What is this article?
NIST/DIN Buffer pH 7.413 250mL is the article on this page. Luminix Health distributes Mettler-Toledo OnLine 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.
