Thermoreactor CR 4200

WTW thermoreactor CR 4200

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

  • 2 digestion programs simultaneously
  • 8 fixed programs for quick operation
  • 8 user-defined programs from 25-170°C with high temperature digestion
  • AQA/IQC with external temperature sensor

Standardized digestion 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 digestions at temperatures between 25-170°C can be programmed for special degradations and therefore also allow high temperature digestions. Two different programs for 12 cuvettes each can be run at the same time. You can use an external temperature sensor instead of a vial with data output to the PC/printer for analytical quality assurance (AQA).
