Description
Sea sand, p.a., purified and calcinated by acid is a high-purity silica laboratory reagent with the empirical formula SiO₂, CAS number 14808-60-7 and EG nr. 238-878-4. Acid purification and calcination remove organic and soluble impurities, yielding a clean granular material suited to analytical and preparative work. The boiling point exceeds 2200 °C, reflecting the thermal stability of silicon dioxide under extreme heating. a. sea sand is commonly used as a boiling aid, filtration support, drying or ignition bed, and inert packing medium in columns and combustion setups. Its purified, calcinated quality reduces background contamination in sensitive procedures. Product from manufacturer Carl ROTH meets pro analysi expectations for general laboratory silica sand. Laboratories rely on such material for even heat distribution, mechanical support of samples and as a chemically inert filler. The defined CAS identity and acid-treated, calcined preparation make this sea sand a practical standard reagent for routine analytical chemistry, sample preparation and high-temperature laboratory operations.

Questions about Sea sand, p.a., purified and calcinated by acid, 1 kg, plastic
What is this article?
Sea sand, p.a., purified and calcinated by acid, 1 kg, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
