Description
Potassium hydroxide is supplied as p.a. pellets with a minimum content of 85 %, CAS number 1310-58-3 and empirical formula KOH. Key physical data include a molar mass of 56,11 g/mol, density of 2,04 g/cm³ and boiling point of 1327 °C, supporting predictable behaviour in analytical and process chemistry. provides a practical laboratory quantity for preparing alkaline media, titrants and digestion solutions. Potassium hydroxide from manufacturer Carl ROTH is used in calibration-related workflows, TAN/TBN support chemistry, volumetric solutions and general inorganic analysis where a strong base in pellet form is required. EG nr. 215-181-3 and the p.a. specification aid method documentation and batch control. Pellet geometry eases weighing and dissolution compared with fine powders, while the stated assay enables consistent preparation of aqueous KOH solutions for laboratory and analytical applications that demand a reliable alkali source.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Potassium hydroxide, min. 85 %, p.a., pellets, 1 kg, plastic
What is this article?
Potassium hydroxide, min. 85 %, p.a., pellets, 1 kg, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Analytical grade solvents (p.a.), inside Solvents, in Lab chemicals.
An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is Analytical grade solvents (p.a.). The catalogue is Lab chemicals.
Shelves beside this one are HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
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.
