Description
di-Sodium tetraborate decahydrate is an inorganic borate salt supplied at min. 99 % in pharmacopoeia-aligned quality grades Ph.Eur., BP and NF. Identified by CAS number 1303-96-4 and EG nr. 215-540-4, it has the empirical formula Na₂B₄O₇ · 10 H₂O, a molar mass of 381,37 g/mol and a density of 1,73 g/cm³. is intended for laboratory use in buffer systems, pH adjustment, analytical reagents and applications that specify borax decahydrate of defined purity. Its crystalline hydrate form dissolves readily for preparation of standard solutions and media components in chemical, pharmaceutical and educational laboratories. This material is offered from manufacturer Carl ROTH for users who require clear pharmacopoeia references alongside assay and identity data. Documented molar mass, density and regulatory identifiers support method writing and incoming-goods checks, while the plastic packaging suits weighing, storage and day-to-day handling in inorganic salt inventories.
This article is part of Inorganic salts, in Inorganic chemicals.

Questions about di-Sodium tetraborate decahydrate, min. 99 %, Ph.Eur., BP, NF, 500 g, plastic
What is this article?
di-Sodium tetraborate decahydrate, min. 99 %, Ph.Eur., BP, NF, 500 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Inorganic salts, inside Inorganic chemicals, in Produits chimiques.
An inorganic salt is an ionic solid, a chloride, a sulfate, a nitrate, a phosphate. The degree of hydration changes the mass that contains one mole of the ion. Analytical grade limits the foreign ions. A hydrate and the anhydrous salt are not interchangeable by weight.
An inorganic chemical is a salt, an acid or base in solid form, a metal, an oxide, or an element. The waters of hydration are part of the formula: a hydrate and an anhydrous salt are different masses for the same ion. Trace metals matter when the salt will be used in analysis. Nanomaterials add particle size to the specification. Look the substance up on PubChem. Hazard classes are on ECHA, under the CLP Regulation and REACH. Transport of the dangerous ones is explained by the UNECE.
Which category should I open next?
The category is Inorganic chemicals. The sub-category is Inorganic salts. The catalogue is Produits chimiques.
Shelves beside this one are Metals, elements & oxides and Nanomaterials & quantum dots.
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.
