COD DIGESTOR

Description

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.
