"STEM kits"

Hydrogen Peroxide CHEMets® used to to monitor sterilisation solutions in the packaging and sanitizing processes.

Ideal for low- to medium-range colorimetric analysis of water quality

CHEMetrics test kits measure total acid soluble sulfides and employ the methylene blue methodology. Sulfides react with dimethyl-p-phenylenediamine in the presence of ferric chloride to produce methylene blue.

The ammonia test kits employing the well-established Nessler reagent to determine ammonia concentrations are applicable to drinking water, clean surface water, and good-quality nitrified wastewater effluent.
