Description
Conductivity standard ROTI®Calipure is a ready-to-use reference solution specified at 648 µS/cm (20 °C) for calibration and verification of conductivity meters, probes, and laboratory cells. Density is 1,001 g/cm³ and the boiling point is 100 °C, offering clear physical-property information for handling and records. Delivered in a 500 ml plastic bottle, the standard is practical for routine instrument checks, quality-control protocols, and method validation in water analysis and general analytical laboratories. The mid-range conductivity value at the stated reference temperature supports confirmation of electrode performance and meter accuracy under defined conditions. This ROTI®Calipure preparation from manufacturer Carl ROTH is intended for determination of conductivity within physical-property testing workflows. The plastic pack format eases bench use and dispensing, and the 500 ml volume covers multiple calibration events. Laboratories rely on temperature-specified aqueous standards to keep measurement series consistent and to support internal quality requirements. Selecting a defined 648 µS/cm reference helps establish reliable baseline response for conductivity determination across successive runs.
This article belongs on Conductivity meters & cells, in pH & electrochemistry. See also pH meters.

Questions about Conductivity standard ROTI®Calipure, 648 µS/cm (20 °C), 500 ml, plastic
What is this article?
Conductivity standard ROTI®Calipure, 648 µS/cm (20 °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.
