Bases

(Showing 12 of 1014)

Neutralizing, titrating, and adjusting pH all depend on bases that arrive at the stated strength. Thermal Scientific stocks laboratory bases and standardized alkaline solutions, including sodium hydroxide, potassium hydroxide, and ammonium hydroxide, in a range of normalities and container sizes. Oil and gas labs commonly use alcoholic potassium hydroxide titrants for acid number testing on petroleum products, and our selection includes potassium hydroxide in isopropanol and methanol alongside general chemistry and water testing solutions.

Pair your bases with acids and acid solutions for neutralization work, indicators for visual endpoints, and buffers for pH control. Browse our full reagents and titrants selection, or reorder regular items through our Vendor Managed Inventory program.
