Thermoreactors are needed for chemical decomposition, such as COD, total nitrogen or total phosphorus. They guarantee complete decomposition because they maintain a high temperature for a defined period of time. Each WTW thermoreactor has permanently entered decomposition programs with the most important temperatures and times: a simple choice of 5 programs at your disposal.

In addition, the CR 3200 and CR 4200 thermoreactors have the ability to store, in addition to 5 fixed, 8 custom programs. Holes with an outer diameter of 16 mm are suitable for reaction cuvettes. The thermoreactors are convincing due to the optimal heat exchange between the heating block and the cuvette as well as the safety measures used.

An integrated guard protects against spraying of chemicals when the cuvette is broken, if any, and burns when touching the surface of the heating block. All units have corresponding stopwatch functions. On all reactors, information about reaching the reaction temperature is shown.
