Description
Silicone oil M 350 is a medium-viscous polydimethylsiloxane fluid with a nominal viscosity of 350 cSt, supplied for laboratory and technical applications. Identified by CAS number 63148-62-9, it offers a density range of 0,967 to 0,975 g/cm³ and a flash point above 300 °C, supporting use where thermal stability and controlled flow behaviour are required. The product is Its medium viscosity balances pourability with film-forming characteristics, making it practical for baths, calibration setups, and equipment lubrication where a stable, low-volatility silicone fluid is preferred. This grade is available from manufacturer Carl ROTH as a clearly specified M 350 quality, enabling straightforward matching to existing protocols that call for 350 cSt silicone oil. Consistent density and high flash point support reproducible handling across routine laboratory workflows without introducing unnecessary formulation complexity.

What is this article?
Silicone oil M 350, medium viscous, 350 cSt, 1 kg, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Essential oils & fragrances, inside Natural products & essential oils, in Lab chemicals.
An essential oil is the volatile fraction distilled or pressed from a named plant part. The species, the chemotype and a stated component, when the seller gives one, are the specification. A fragrance compound is a formulated mixture. The two should not be treated as the same bottle.
A natural product is a molecule extracted from a plant, an animal or a microorganism, or a mixture of those molecules. An essential oil is the volatile fraction. The useful specification is the source species, the plant part and, where it exists, the stated content of a marker compound. Two oils with the same common name are not the same article. Marker compounds are identified on PubChem and named by IUPAC.
