HI 839800 COD Test Tube Heater / COD Reaktor HANNA 25 vial hole

The HI839800 COD Test Tube Heater features two predefined temperature profiles: 150\C and 105\C. Digestions for chemical oxygen (COD) and total phosphorus are conducted at 150\C, while total nitrogen digestions are conducted at 105\C. The test tube heater automatically heats up to the set temperature, holding it until the countdown timer has finished. Once the timer has ended, a beep will sound and the heating element will turn off. The outer casing of the HI839800 remains cool to the touch, even during a timed digestion. An optional lab safety shield and test tube cooling rack provide a complete setup for sample digestions.
