Description
Silica gel orange is a pearl-form desiccant with particle size 2–5 mm and an integrated colour indicator for visual monitoring of moisture uptake. Registered under CAS number 1327-36-2 and EG number 215-475-1, it is described with a boiling point above 999 °C, reflecting the thermal stability expected of silica-based drying media. The orange indicator grade helps users judge saturation status during storage of moisture-sensitive chemicals, instruments and sample containers. This silica gel orange comes from manufacturer Carl ROTH and fits laboratory routines that rely on regenerable or replaceable indicator gels. Its defined bead size supports even packing and airflow, while the colour change provides a practical cue for maintenance of dry atmospheres in cabinets, jars and sealed systems without complex instrumentation.
This article is part of Sorbents, silica gel & ion exchangers, in SPE & sample preparation.

Questions about Silica gel orange, 2-5 mm, with colour indicator, pearls, 1 kg, plastic
What is this article?
Silica gel orange, 2-5 mm, with colour indicator, pearls, 1 kg, 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.
