Works with Thermo Scientific Orion COD kits or any 16 mm COD vial. The simple two-button interface, combined with the auto-shutoff feature, easily sets the reactor to digest up to 25 vials at once. Preset reaction times of 30, 60, or 120 minutes eliminate the need for an external timer. Use continuous mode for other digestion times. Set the temperature to 100°C, 120°C, 150°C, 160°C, or 165°C to start the reactor.
