Thermoreactor CR 3200

WTW thermoreactor CR 3200

CR 3200 thermoreactor for thermal digestion with 2x12 round cuvettes with 8 fixed / 8 user-defined programs with temperatures of up to 170°C and AQA

  • 8 fixed standard programs for simple operation
  • 8 user-defined programs of 25-170°C with high temperature digestion
  • AQA/IQC with external temperature sensor

Standardized digestion with programs for the standard parameters COD, quick COD (148°C, 20 min.), total nitrogen, total phosphorus, TOC and heavy metals of galvanizing with automatic heating and switch-off. 8 user-defined digestion programs at temperatures between 25-170°C can be programmed for special degradations and therefore also allow high temperature digestions. The very same program can be run for all cuvettes at the same time; to perform two parallel digestion programs, the CR 4200 is the suitable choice. For the analytical quality assurance (AQA), the external temperature sensor TFK CR can be connected to the PC/printer instead of a vial.
