Description
Silica gel 60 C₁₈ is an octadecyl-functionalized chromatographic silica with particle size 0,035-0,07 mm (400-220 mesh), CAS number 7631-86-9 and empirical formula SiO₂. It has a molar mass of 60,09 g/mol and a density of 2,1 to 2,2 g/cm³, giving a well-defined reversed-phase stationary phase for laboratory use. C₁₈-bonded Silica gel 60 is widely applied for hydrophobic retention of non-polar and moderately polar analytes in reversed-phase separations. Laboratories use this material for purification of organic compounds, natural-product fractions and pharmaceutical intermediates where long-chain alkyl surface chemistry provides strong non-polar interaction. The product from manufacturer Carl ROTH pairs the established Silica gel 60 support with C₁₈ modification and a tight 400-220 mesh specification for consistent bed formation and flow. It supports research, preparative and quality-control workflows that need reproducible particle size together with documented density and molar-mass data for routine chromatographic practice.

Questions about Silica gel 60 C18, 0,035-0,07 mm (400-220 mesh), 50 g, glass
What is this article?
Silica gel 60 C18, 0,035-0,07 mm (400-220 mesh), 50 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Sorbents, silica gel & ion exchangers, inside SPE & sample preparation, in Chromatography equipment.
Loose sorbent, silica gel and ion-exchange resin are the phases bought in bulk to pack a column or to stir into a solution. Particle size and activity, or the ion-exchange capacity, are the specification. A TLC silica and a flash silica of different particle sizes are not the same separation.
Solid-phase extraction holds a compound on a sorbent while the rest of the sample is washed away, then releases it in a small volume. The sorbent, the bed mass and the solvents are the method. Silica, ion exchangers and polymer phases do different jobs. A flash column is the same idea scaled toward purification rather than trace cleanup. The molecules are on PubChem, named by IUPAC.
Which category should I open next?
The category is SPE & sample preparation. The sub-category is Sorbents, silica gel & ion exchangers. The catalogue is Chromatography equipment.
Shelves beside this one are SPE cartridges & columns and Flash, empty & glass chromatography columns.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
