CR 2200 is ideal for anyone who needs to perform routine water analysis tests with small sample amounts, as 5 programs are available for digestion of 12 sample cuvettes at 212, 248 and 298.4 °F (100, 120 and 148 °C).
In addition, you can program the CR 3200 to carry out 8 of your individual digestions at freely selectable temperatures up to 338 °F (170 °C).
CR 4200 is the right choice for anyone who needs to perform multiple tests simultaneously, such as COD (298.4 °F/148 °C) and total-N (248 °F/120 °C), as the two thermoblocks for 12 cuvettes each can be controlled separately. It also has memory for 8 of your own user-defined programs with free temperature selection up to 338 °F (170 °C).

Nucleic acids are necessary biomolecules of living systems being fundamentally important to a multitude of cellular processes. Its basic building blocks are nucleobases (e.g., adenine, cytosine, xanthine), nucleosides (e.g., adenosine, guanosine, inosine), and nucleotides (e.g., ATP, CDP, dGTP). The qualification/quantification of these compounds, and their synthetic analogs (e.g., 5-fluorouracil), in biosamples, is performed…
