Micromac Lab II

Automatic laboratory analyser for chrome-based COD analysis.

Fully automaticµFLR technology-based analyser with automated batch analysis, designed for COD determination in liquid samples. The system automatically handles sample dosing, reagent addition, digestion, reading, and final washing.

Integrated samplerEquipped with a robust 8-position sequential sampler, compatible with 100 mL or 250 mL bottles, simple to use.

Easy to useIt does not require an external PC. The integrated 8″ colour touchscreen display allows for complete instrument control; simply enter the number of samples and start the analysis.

Calibration3-point calibration plus zero with manual start. The calibration equation is stored in the Touch Screen software memory.

Sample analysisSequential sample management via Touch Screen software with progressive numerical identification and sequential access to samples.

Results ManagementThe results are stored in the instrument's memory and can be exported via USB in CSV format.

Micromac Lab II analyser with minisampler

Measurement principle

The sample is dosed into the digestion tube, where mercury sulphate, potassium dichromate, and sulphuric acid with a catalyst are added sequentially. Digestion is performed automatically at 175°C. After digestion and cooling, absorbance is measured at 592 nm and 70°C. Following the measurement, the sample is discharged and the system automatically washes the hydraulic parts and the digestion tube with deionised water.

Advantages and benefits

Easy to use; no specific experience or dedicated training required;
low operating costs; maintenance required every 6-12 months;
Quick start-up; simply insert the work list and start the analysis.;
Automatic washing and stand-by mode at the end of analyses, with no reagent consumption;
intuitive integrated software, designed specifically for operators and chemical laboratories;
fully automatic operation without continuous supervision;
possibility of operating overnight with unattended analysis;
USB port for exporting results in CSV format.
