Overview

Product Features
  • 2x12 round cells (16 mm) for 2 simultaneous digestion programs
  • 8 pre-programmed settings including fast digestion for COD
  • Easy, quick operation for standard parameters
  • AQA/IQC with external temperature sensor

The WTW Thermo Reactor CR 4200 is a dry temperature control device for use in the laboratory. It facilitates and safeguards the digestion with reaction cells.

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).

8 standard digestion programs are included 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 digestions allowing also high temperature digestions.

Programs for standard parameters:

  • 1: 148 °C for 120 minutes
  • 2: 120 °C for 30 minutes
  • 3: 120 °C for 60 minutes
  • 4: 120 °C for 120 minutes
  • 5: 100 °C for 60 minutes
  • 6: 148 °C for 20 minutes
  • 7: 150 °C for 120 minutes
  • 8: 100 °C for 30 minutes
