THERMOREACTOR - ECO 8 - VELP

Chemical Oxygen Demand means the amount of oxygen from chemical oxidants required for the complete oxidation of substances dissolved or suspended in water. By COD determination it is possible to quantitatively evaluate substances which can be oxidized by strong oxidants like potassium dichromate in highly acidic solutions by concentrated sulphuric acid. Both organic and inorganic substances can be oxidized. The method allows the determination of substances which are not oxidized by the corresponding biological method (BOD = Biological Oxygen Demand), for example cellulose. Chemical oxidation is more complete than biological oxidation and therefore COD values for a given sample are generally higher than BOD values.

Thermoreactor

Thermoreactor ECO 8 has a capacity of 8 round glass test tubes with 16 mm external diameter and for 1 test tube with 22 mm external diameter. It is devised for sample preparation in determining COD, total phosphorus, total chromium and other parameters in water and sludge.

Having a limited space requirement, the instrument is covered by an epoxy paint which makes it highly resistant to the chemical corrosion.

An excellent tests reproducibility is assured and can be selected 5 different working temperatures:
70, 100, 120, 150C, 160C and 4 different times for the selected temperature: 30, 60, 120 min or infinite time.

A voltage changer, allows a connection to electric nets 230 V or 115 V.
The complete working safety is assured by:
test tubes cover, protection on the heating block, safety thermostat.
