Environmental Express® TKN Blocks and Controllers

Components to build your TKN system

Environmental Express HotBlock® TKN System provides an efficient method of digesting and storing water, wastewater, soil and sludge samples for Total Kjeldahl Nitrogen (TKN) analysis, total phosphorous (TP or TKP); total metals digestions, or other digestion methods requiring temperature up to 450°C. These innovative digestion systems allow samples to be digested in a corrosion-free environment. In addition, samples are handled in a small area with minimal radiant heat loss.
