KCl is a chemical standard solution prepared with Potassium Chloride dissolved in distilled water, formulated at precise concentrations that ensure stable and accurate electrical conductivity. It is linked to international standards such as NIST. It is mainly used for the calibration and verification of conductivity meters, ensuring accurate readings and reproducible measurements in research and industrial environments.
Applications
Filling solution for electrodes requiring a medium- or high-stability potential.
Salt bridge maintenance in electrochemistry and potentiometry.
Ionic control in specific assays and pH measurements.
Preparation of standard solutions and dilution solutions that require a stable electrolyte.
Use in laboratories to prevent contamination or dehydration of the electrode during storage.
