Description

Thermoreactor, COD Analysis – ECO16

16-position thermoreactor for Chemical Oxygen Demand (COD) with settable temperature (up to 160 °C) and operating time (up to 199 minutes).

The ECO 16 thermoreactor is used to determine parameters such as COD and nitrogenous and phosphorous compound content of test-tube samples. Safe and reliable conditions are ensured by the test-tube cover and safety thermostat.

The reaction time can be set from 1 to 199 minutes or to continuous mode and the temperature setting is shown on the display (from room temperature to 160C). An acoustic signal indicates the end of the oeprating cycle with automatic switch-off.

The aluminum heating block offers optimum thermal omogeneity at all selected temperatures.

The heating block temperature is controlled by a PID logic microprocessor.

Accurate Operation

•  Electronic temperature control
•  Temperature regulation from ambient to 200 °C
•  Analysis time can be set from 1 to 199 minutes or continuous

Large Sample Numbers

•  Processes up to 14 x Ø 16 mm ml test tubes
•  Plus 2 x Ø 22 mm test tubes simultaneously
•  LCD countdown display shows the temperature and remaining time

Reduced Running Cost

•  COD analysis in only 30 minutes at 160 °C
•  16 mm diameter tubes minimize reagent consumption

Safety in Use

•  Automatic shut-down at run end
•  Acoustic signals, e.g., at shut-down
•  Antisplash cover protects the user

ECO thermoreactors are suitable for COD analysis and for sample preparation

ECO thermoreactors are suitable for COD analysis

Also known as Chemical Oxygen Demand

Plus for sample preparation

In order to determine both metallic and non-metallic elements in organic and inorganic materials such as minerals, alloys, animal feeds, soils, sediments and organic tissues

A typical COD analysis is usually long

– It will usually take 2 hours at 150 °C
– VELP ECO Series can perform COD analysis in only 30 minutes thanks to the higher temperature of 160 °C

The aluminum heating block offers optimum thermal conditions and a high level of homogeneity at all temperatures
The ECO-series thermoreactors are also suitable for determining total organic carbon (TOC), total chromium, total nitrogen and total phosphate and ensure excellent accuracy and repeatability

BENEFITS

Intuitive Parameters Setting, Digital Display

COD Analysis Thermoreactor ECO 16 ensures a simple and easy programming of time and temperature, the parameters involved in the analysis.
Through the digital display it is possibile to monitor the test at any time, with the countdown constantly shown.
The unit automatically shuts down when the analysis time expires, whilst safety is of primary importance, as demonstrated by the several acoustic and visual signals that report unpleasant situations.

High Safety Rating and Rapid Micro Digestion Method

The micro digestion method minimizes reagent consumption and reduces the required space and equipment to one reactor block that works on several samples at the same time.
Each test set-up is a self-contained disposable vial, which is inserted into a heating system, using small amounts of reagent and sample and so decreasing both the cost and the waste volume.
ECO 16 is suitable for performing a short time COD analysis, in only 30 minutes with a high digestion temperature (160 °C).
ECO Series ensures a high safety level, thanks to the transparent test tube cover that offers a constant visual control of the sample and to all the safety features related to the temperature control of the heating block.
