Beschrijving
Silica gel 60 is een chromatografisch sorptiemiddel met deeltjesgrootte 0.2–0.5 mm, CAS-nummer 7631-86-9, EG-nummer 231-545-4 en empirische formule SiO₂. De molaire massa is 60.09 g/mol en de dichtheid ligt tussen 2.1 en 2.2 g/cm³. Deze eigenschappen maken het materiaal geschikt als stationaire fase of bulksorptiemiddel bij kolomchromatografie en verwante scheidingstechnieken waarbij silica gel 60 in de fractie 0.2–0.5 mm is gespecificeerd. Deze silica gel 60 komt van fabrikant Carl ROTH en behoort tot de sorptiemiddelen die worden gebruikt voor analytische en preparatieve chromatografie. De gedefinieerde deeltjesgroottefractie helpt een reproduceerbare stroming en bedkarakteristieken te bereiken wanneer kolommen volgens de standaard laboratoriumpraktijk als slurry of droog worden gepakt.
Dit artikel maakt deel uit van Sorbentia, silicagel & ionenwisselaars, in SPE & monstervoorbereiding.

Questions about Silica gel 60, 0.2-0.5 mm, 500 g, kunststof
What is this article?
Silica gel 60, 0.2-0.5 mm, 500 g, kunststof is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Sorbentia, silicagel & ionenwisselaars, inside SPE & monstervoorbereiding, in Chromatografie.
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 & monstervoorbereiding. The sub-category is Sorbentia, silicagel & ionenwisselaars. The catalogue is Chromatografie.
Shelves beside this one are SPE-cartridges & kolommen and Flash-, lege & glazen chromatografiekolommen.
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.
