Silica Gel Blue 99% Lab. Grade

Cas No. 112926-00-8

Description:

Silica Gel Blue is commonly used in laboratories as a desiccant, absorbent, or stationary phase in chromatography. It’s essentially a porous, granular form of silicon dioxide , which has high surface area and is capable of adsorbing a wide range of substances, particularly moisture.

1. Appearance: Silica Gel Blue is typically a transparent or slightly opaque material, often appearing as small beads or granular particles. It can come in various forms, such as white, blue, or orange, depending on whether it’s been treated with moisture indicators or other chemicals.
2. Structure: It has a highly porous structure, with a vast network of tiny pores that give it a high surface area. This allows it to absorb or adsorb large amounts of water or other molecules.
3. Chemical Properties: Silica Gel Blue is chemically inert, non-toxic, and non-flammable, making it very safe for use in laboratories. It does not react with most chemicals, which is one of the reasons it’s widely used.
4. Uses in the Laboratory:
   • Desiccant: It’s used to absorb moisture from environments or containers to prevent the degradation of moisture-sensitive materials. For example, It is placed in desiccators to protect samples from absorbing ambient moisture.
   • Chromatography: Silica gel is also a popular stationary phase in thin-layer chromatography (TLC) and column chromatography. In these methods, it helps separate components of mixtures based on their polarity or affinity for the silica surface.
   • Purification: It’s sometimes used in processes to purify compounds or substances by selectively adsorbing contaminants or undesired molecules.

Storage and Handling:

• Silica Gel Blue should be stored in a dry place, and it’s often regenerated (re-dried) by heating it to remove adsorbed moisture.
• While generally non-toxic, silica gel (especially if it’s the type with moisture indicators like cobalt chloride) should be handled carefully to avoid ingestion or inhalation of fine particles.
