Heating block is designed for use with digestion samples C.O.D. (148°C) and sludge phosphorus (100°C) analysis.

Both operating temperatures, are preset at the factory. This feature reduces errors and increases the reliability of results. Accurate timing is maintained as the timer only starts once the sample has reached the correct test temperature.

The RECOD 19 was designed to use 17 test tubes Ø 16 mm (2 ml) plus 2 holes Ø 22 mm for phosphorous test tubes. Kits of tubes with the reagent can also be purchased.

The RECOD 6, 6 holes Ø 42.5 mm (20 ml) reactor performs analysis according to ISO specifications.
