Sodium Hydroxide (NaOH) and Sodium Hydroxide Solutions

Buy Sodium Hydroxide (NaOH) and Bulk Order Caustic Soda, Lye, Sodium Hydrate

What is sodium hydroxide?

NaOH is a strongly basic versatile inorganic compound often referred to as caustic soda, lye, or sodium hydrate. This common laboratory alkali is used for general cleaning of equipment, buffer solutions, and titrations, among other uses. In the home, NaOH is found in soaps, cleaning agents, and even foodstuffs like wine.

Use the links below to buy NaOH as powder, pellets, or in solution for luminescence, molecular biology, cell culture, semiconductors, and ion chromatography.

Choose from common concentration values, purities from 97%, and grades from to meet your commercial, educational, food, drug, or medicinal applications. Available grades include ACS reagent, analytical, Ph. Eur., Puriss, Puriss P.A., BioUltra, BioXtra, and Purum.

Product detail pages provide full information, including documentation, safety data, and lists of common trace anion and cations or impurities.
