Description
Sodium hydroxide is a strong base offered at min. 98 % purity in p.a., ISO grade as solid pellets. Identified by CAS number 1310-73-2 and EG number 215-185-5, it has the empirical formula NaOH, a molar mass of 40,0 g/mol, a density of 2,13 g/cm³ and a boiling point of 1388 °C. The pellets are UN number 1823 applies for transport classification of this corrosive solid. Physical constants support calculation of concentrations and process design in wet-chemistry workflows. Available from manufacturer Carl ROTH, this sodium hydroxide grade meets common requirements for analytical reagents where ISO-aligned p.a. quality is specified. The pellet form facilitates handling and weighing while the defined purity supports reproducible results in quality-controlled laboratories.

Questions about Sodium hydroxide, min. 98 %, p.a., ISO, in pellets, 1 kg, plastic
What is this article?
Sodium hydroxide, min. 98 %, p.a., ISO, in pellets, 1 kg, 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.
