Description
Silica Gel Yellow/Blue is a fractured silica gel desiccant with a colour indicator and a particle size range of 2,5–6 mm. Identified under CAS number 7631-86-9 and EG nr. 231-545-4, this material is The yellow/blue indicator allows visual assessment of the hydration state during use as a sorbent or desiccant bed. Density is given as 2,2 g/cm³, supporting calculation of bed volume and packing mass in drying tubes, desiccators, and related apparatus. Fractured granules in the 2,5–6 mm range provide a practical balance between surface accessibility and flow characteristics for bulk filling. Offered from manufacturer Carl ROTH within the silica gels with colour indicator range, the product suits performance-materials and sorbent workflows where a colour-indicating silica gel is required. Pack size, particle fraction, density, and regulatory identifiers are stated so that laboratory documentation and material selection remain straightforward for drying and moisture-scavenging tasks.
This article is part of Sorbents, silica gel & ion exchangers, in SPE & sample preparation.

Questions about Silica Gel Yellow/Blue, 2.5-6 mm, with colour indicator, fractured, 500 g
What is this article?
Silica Gel Yellow/Blue, 2.5-6 mm, with colour indicator, fractured, 500 g 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.

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.
