COD Reactor

The Lovibond RD125 Thermoreactor is for 16mm tubes, 24 slots.

Flexible thermoreactor for sample preparation of photometrical determination of COD, total chrome, total phosphate, total nitrogen and TOC. Digestion is possible with three temperature ranges and three pre-programmed reaction times

FEATURES:
- Three Temperature Ranges: The reactor can operate optionally with 100°C, 120°C or 150°C – depending in each case on the sample to be prepared.
- Three Different Reaction Times: Three different reaction times are available with 30, 60 and 120 minutes. Your advantage: Afterwards the unit switched itself off automatically.
- Large Cuvette Shaft: Place up to 24 16-mm-round cuvettes in the RD 125.
- Voltage Change Possible: The RD 125 can be used with various voltages: Choose 110 V and 220 V with the voltage selector on the back.
