Description
Sodium hydroxide is a high-purity alkali supplied as pellets at min. 98 % and conforming to Ph.Eur., USP and BP monographs. Identified by CAS number 1310-73-2 and empirical formula NaOH, it has a molar mass of 40,0 g/mol, a density of 2,13 g/cm³ and a boiling point of 1388 °C (EG nr. 215-185-5). of pellets is practical for preparing standard solutions, adjusting pH, saponification, and general inorganic synthesis in the laboratory. From manufacturer Carl ROTH, this pharmacopoeia-grade material is also suited to drying and desiccant-related applications where a strong base is required. Its defined assay and multi-compendial status support use in analytical, pharmaceutical and process laboratories that need consistent NaOH quality for titration, media preparation and routine chemical work.

Questions about Sodium hydroxide, min. 98 %, Ph.Eur., USP, BP, in pellets, 500 g, plastic
What is this article?
Sodium hydroxide, min. 98 %, Ph.Eur., USP, BP, in pellets, 500 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Sorbents, silica gel & ion exchangers, inside SPE & sample preparation, in Chromatography equipment.
Loose sorbent, silica gel and ion-exchange resin are the phases bought in bulk to pack a column or to stir into a solution. Particle size and activity, or the ion-exchange capacity, are the specification. A TLC silica and a flash silica of different particle sizes are not the same separation.
Solid-phase extraction holds a compound on a sorbent while the rest of the sample is washed away, then releases it in a small volume. The sorbent, the bed mass and the solvents are the method. Silica, ion exchangers and polymer phases do different jobs. A flash column is the same idea scaled toward purification rather than trace cleanup. The molecules are on PubChem, named by IUPAC.
Which category should I open next?
The category is SPE & sample preparation. The sub-category is Sorbents, silica gel & ion exchangers. The catalogue is Chromatography equipment.
Shelves beside this one are SPE cartridges & columns and Flash, empty & glass chromatography columns.
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.
