Details
Silica Gel Powder, High Purity
high purity silica gel powder is a granular form of silicon dioxide, SiO 2 that is most commonly used as a desiccant. The three-dimensional atomic level arrangement creates voids in its structure which can be filled with water molecules, thus removing moisture from the surroundings. It can be packed with shoes, electronics, and food products to ensure that they stay moisture free in storage and during transit. Both indicating (those that change color on absorbing water), and non-indicating silica gels are available.
Silica gel powder also finds use as the stationary phase in various chromatography applications.
Due to its high purity, this product is recommended for labs and commercial applications.
