| Digestions with 2×12 round cells at 2 different programs |
| With CR 4200 two different digestion programs can be performed for 16 mm vials simultaneously in two seperate heating blocks for 12 vials each. |
| • 8 stored programs for quick operation |
| • 8 user-defined programs from 25-170°C for high temperature digestion up to 170°C |
| • AQA/IQC with external temperature sensor |
| Standard 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 digestions allowing also high temperature digestions. |
| Two different programs for 12 cuvettes each can be run at the same time (CR 3200 offers the smaller solution with 2×12 cuvette at one program at a time). You can use an external temperature sensor instead of a vial with data output to the PC/printer for analytical quality assurance (AQA). |
| Programs for standard parameters |
| • 1: 148 °C for 120 minutes |
| • 2: 120 °C for 30 minutes |
| • 3: 120 °C for 60 minutes |
