Description
Dimethyl sulphoxide (DMSO) is a highly polar organic solvent presented in ROTICHROM® GC quality for gas-chromatographic and analytical laboratory use. It is defined by CAS number 67-68-5, empirical formula C₂H₆OS and EG number 200-664-3, with a molar mass of 78,13 g/mol. Reported physical characteristics include a density of 1,1 g/cm³, a flash point of 87 °C and a boiling point of 189 °C, supporting informed handling in dissolution, reaction and sample-preparation steps. This article is supplied in a 5 ml glass pack, practical for calibration, method development and small-scale experimental work where a defined DMSO grade is preferred. The ROTICHROM® GC material from manufacturer Carl ROTH gives laboratories a compact, clearly labelled source of dimethyl sulphoxide for chromatographic and related chemical applications. CAS and EG numbering assist inventory management, safety filing and regulatory traceability across research and quality-control environments that rely on consistent solvent identity and documented physical data.

Questions about Dimethyl sulphoxide (DMSO), ROTICHROM® GC , 5 ml, glass
What is this article?
Dimethyl sulphoxide (DMSO), ROTICHROM® GC , 5 ml, glass is the article on this page. Luminix Health distributes Carl Roth 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.
