Description
Conductivity standard ROTI®Calipure 25 µS/cm (25 °C) is a ready-to-use reference solution for laboratory determination of conductivity. It delivers a defined conductivity of 25 µS/cm at the reference temperature of 25 °C, supporting calibration and verification of conductivity meters and sensors. Physical data include a density of 1 g/cm³ and a boiling point of 100 °C, which guide handling under ordinary laboratory conditions. The product is supplied in a 500 ml plastic bottle that offers a practical pack size for routine bench-top calibration work and repeated instrument checks. This ROTI®Calipure grade conductivity standard from manufacturer Carl ROTH is intended for applications in the determination of physical properties, specifically conductivity measurement. Quality-control and analytical laboratories use such standards to confirm instrument performance, set reference baselines, and keep measurement series comparable over time. Clear specification of the conductivity value and temperature reference allows straightforward incorporation into standard operating procedures for conductivity determination. The 500 ml presentation supports efficient workflow organisation where low-range conductivity calibration is performed regularly.

Questions about Conductivity standard ROTI®Calipure, 25 µS/cm (25 °C), 500 ml, plastic
What is this article?
Conductivity standard ROTI®Calipure, 25 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.
