Product Description

Aqua Ammonia (Ammonium Hydroxide) is a water solution of ammonia, and assay is determined by weight of ammonia in water. Each batch is tested for strength, color, and clarity. Trace element analysis are performed every 6 months by an independent lab, and are available for review.

For Technical Grade material the trace element specifications will vary depending on the public water supply for each facility. Therefore each facility has its own published trace element specifications.

Reagent Grade material is made using de-ionized or reverse osmosis (R/O) water and meets the American Chemical Society specifications for Aqua Ammonia.
