Automatic COD Reactors

Chemical digestion of the samples is a prerequisite for tests, determination of COD, TOC, total phosphate, nitrogen etc.

The required temperature and reaction time are programmed using the membrane keypad on the front of the reactor.

When digestion is complete, the reactor automatically switches off and sounds an alarm. The DBR-001 COD reactor is designed to meet USEPA 410.4 method. It can be used to digest closed I micro reflux COD vials and other samples with a 16mm diameter.

Furthermore, it is safer and easier than traditional open macro reflex method.

A unique COD program lets DBR-001N/002N be a truly automatic reactor.

When the reactor is powered on, just click the start/stop button, then it starts to heat to 150°C and keep for 2 hours then stop heating with an audio alarm. Samples are ready to be measured by colorimeter when they cool down.

DBR-001N/002N COD reactor is compatible with any COD detectors which use 16mm COD vials. In additional to the COD program, DBR-001N/002N is a microprocessor controlled block heater, with temperature range from 60°C to 200°C and a timer from 0 to 999 minutes or continuous operation.
