MP EchoChrom Silica Plates F254, 20 Plates

MP EcoChrom™ Silica Plates cover a wide range of Thin-Layer Chromatography applications. Their uniform surface makes MP silica plates suitable for quantitative densitometric UV/VIS evaluation. They are available without any fluorescent indicator or with fluorescent indicators for 254 nm or for 254 and 366 nm activation wavelength. MP EcoChrom™ Silica is used as a suspending and thickening agent in pharmaceuticals. A silica-based aerogel was used in the Stardust spacecraft to collect extraterrestrial particles. Silica is also used in the extraction of DNA and RNA due to its ability to bind to the nucleic acids under the presence of chaotropes. As hydrophobic silica it is used as a defoamer component. In hydrated form, it is used in toothpaste as a hard abrasive to remove tooth plaque. SiO2 has a number of distinct crystalline forms (polymorphs) in addition to amorphous forms. In the majority of silicates, the Si atom shows tetrahedral coordination, with 4 oxygen atoms surrounding a central Si atom.
