Description
Silica gel orange/green is a pearl-form laboratory desiccant with colour indicator and a particle size range of 2–5 mm. The beads are intended for moisture adsorption in desiccators, drying trains and related sorption setups, giving a clear visual cue as the indicator shifts between orange and green when the gel approaches saturation. Density is specified at 2,2 g/cm³, in line with dense silica gel pearls used in analytical and preparative environments. This grade belongs to silica gels with colour indicator and sits among sorbents and filter media for performance-materials work. Laboratories can deploy the pearls wherever controlled low-humidity conditions and straightforward capacity checks are required. Defined bead size, indicator response and convenient packaging make the material a practical choice for day-to-day desiccation in research, quality-control and general laboratory settings that rely on reversible moisture uptake.
This article belongs on Sorbents, silica gel & ion exchangers, in SPE & sample preparation.

Questions about Silica gel orange/green, 2-5 mm, with colour indicator, pearls, 500 g, plastic
What is this article?
Silica gel orange/green, 2-5 mm, with colour indicator, pearls, 500 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.

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.
