Description
Silica gel 150 is a chromatography-grade sorbent based on silicon dioxide, empirical formula SiO₂ (CAS 7631-86-9), with a particle size range of 0,07–0,2 mm (70–220 mesh). Molar mass is 60,09 g/mol and density lies between 2,1 and 2,2 g/cm³, supporting reliable use as a stationary phase in column chromatography and related separation work. The coarser 70–220 mesh fraction favours good flow characteristics and packing behaviour in many standard columns. This silica gel 150 from manufacturer Carl ROTH belongs to the silica gels for chromatography range used across analytical chemistry laboratories. It is suitable for fractionation, purification, and method setup where a defined silica particle distribution is required. Identification includes EG nr. 231-545-4, consistent with established silica gel specifications for research and routine quality-control applications.

Questions about Silica gel 150, 0,07-0,2 mm (70-220 mesh), 250 g, plastic
What is this article?
Silica gel 150, 0,07-0,2 mm (70-220 mesh), 250 g, plastic 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.
