Description
Conductivity standard ROTI®Calipure 2500 µS/cm (25 °C) is a ready-to-use laboratory reference solution for conductivity determination and instrument calibration at 2500 µS/cm (25 °C). It is intended for checking conductivity meters, measurement cells and related sensors in analytical and quality-control laboratories that work with higher-range aqueous samples. Density is given as 1,001 g/cm³ and the boiling point as 100 °C, consistent with an aqueous calibration medium for regular laboratory use. The solution comes in a 500 ml plastic bottle, a practical format for bench-top calibration cycles and shared laboratory stocks. This ROTI®Calipure standard from manufacturer Carl ROTH supports applications in the determination of physical properties, with a focus on conductivity measurement in research, industrial QC and educational environments. A defined, ready-prepared conductivity reference reduces in-house preparation effort and helps keep instrument performance stable across users and measurement series. The product suits laboratories that need a clearly stated conductivity value at a specified temperature for reliable day-to-day calibration workflows.

Questions about Conductivity standard ROTI®Calipure, 2500 µS/cm (25 °C), 500 ml, plastic
What is this article?
Conductivity standard ROTI®Calipure, 2500 µS/cm (25 °C), 500 ml, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Conductivity meters & cells, inside pH & electrochemistry, in Lab instruments.
A conductivity meter and its cell measure how well a solution carries current. The cell constant is the geometry that converts conductance to conductivity, and it is calibrated with a standard. Temperature compensation matters because conductivity rises with temperature.
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.
