Description
Silica gel blue is a pearl-form desiccant silica gel supplied in the 2–4 mm size range with an integrated colour indicator for visual monitoring of moisture uptake. It is Key physical data include a density of 2,2 g/cm³ and a boiling point of 2300 °C. The material is identified under CAS number 7631-86-9 and EG nr. 231-545-4. In sorbent and filter-media applications, blue indicating silica gel is widely used to control humidity in desiccators, instrument cabinets and sealed containers, allowing staff to judge remaining drying capacity at a glance. This grade from manufacturer Carl ROTH is presented as pearls suited to bulk filling of drying tubes, jars and humidity-control inserts.
This article is part of Sorbents, silica gel & ion exchangers, in SPE & sample preparation.

Questions about Silica gel blue, 2-4 mm, with colour indicator, pearls, 500 g, plastic
What is this article?
Silica gel blue, 2-4 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.
