Thermoreactors
Thermoreactors for the disintegration of COD, total nitrogen and total phosphorus, including brief and self-programmed high temperature disintegration up to 170°C
| _white_ | CR 2200 | CR 3200 | CR 4200 |
| 8 standard programs | _X_ | _X_ | _X_ |

The high reaction temperature over a defined period of time ensures a complete degradation of the sample. The required temperatures and degradation times for the standard parameters are stored in every WTW thermoreactor. In addition, there are different options for self programming and cuvette numbers available.
8 fixed programs for standard parameters
