Description
KCl-250 is a reference electrolyte supplied as potassium chloride solution at 3 mol/l concentration. The product comprises one bottle containing 250 ml of ready-to-use KCl solution for laboratory electrode work. It is intended as a filling and maintenance electrolyte for reference electrodes used in pH, redox and ion-selective measurements where a stable junction potential is required. The 3 mol/l formulation supports consistent electrode response during routine analytical procedures in quality control, research and environmental laboratories. Packaged as a single 250 ml bottle, the unit offers a practical volume for electrode filling, storage and refilling on the bench. This reference electrolyte from manufacturer WTW - a Xylem brand is suited to combination glass electrodes and separate reference systems that specify potassium chloride electrolyte. Net weight is 0,297 kg, with a gross weight of 0,33 kg, making the bottle convenient for everyday laboratory handling. Use according to the electrode manufacturer’s instructions ensures reliable potential readings and prolonged sensor service life in electrochemical applications.

Questions about KCl-250, Reference electrolyte, 1 bottle with 250 ml KCl solution 3 mol/l.
What is this article?
KCl-250, Reference electrolyte, 1 bottle with 250 ml KCl solution 3 mol/l. is the article on this page. Luminix Health distributes WTW - a Xylem brand for laboratory use. It sits in pH electrodes & sensors, inside pH & electrochemistry, in Lab instruments.
A pH electrode is a glass membrane and a reference. It is a consumable: the glass ages, the junction clogs, and the reading drifts. A refillable electrode and a gel electrode differ in how they are maintained. The connector has to match the meter. The electrode, not the meter, is usually what is wrong.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
