Beschrijving
Technical buffer pH 12.45 is a ready-to-use calibration solution intended for accurate adjustment and verification of pH electrodes and meters in laboratory, process and industrial analytical environments. This technical-grade buffer delivers a defined alkaline pH value of 12.45 and is supplied in a practical 250 mL pack with a net weight of 0,25 kg, supporting routine calibration without unnecessary excess volume. The solution is traceable to certified international SRM-NIST standards, ensuring reliable measurement accuracy and reproducibility for quality-control and analytical workflows. Offered by manufacturer Mettler-Toledo OnLine, the buffer is well suited to chemical analysis, environmental monitoring, pharmaceutical testing and other applications requiring a stable alkaline reference point. Its gross weight of 0,301 kg reflects robust packaging that facilitates safe handling and convenient laboratory storage. The ready-to-use format minimises preparation time while preserving the integrity of the certified reference linkage. Laboratories rely on this technical pH buffer for consistent electrode slope and offset calibration across diverse scientific disciplines where dependable alkaline standards are essential.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about Techn. Buffer pH 12.45 250mL
What is this article?
Techn. Buffer pH 12.45 250mL is the article on this page. Luminix Health distributes Mettler-Toledo OnLine for laboratory use. It sits in pH-buffers & geleidbaarheidsstandaarden, inside Buffers & pH-oplossingen, in Chemicaliën.
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.
