Product features:

1. Determine the actual oxygen consumption of the sample by charge movement;

2. No need to dilute the sample: the maximum detection limit can reach 10000 mg;

3. Continuous electrolytic oxygen supply: each bottle of electrolyte can provide several years of electrolytic oxygen. After the electrolyte is used up, it can be used after adding new electrolyte;

4. Precision temperature control:Water bath temperature control, temperature setting range 5-99 ℃, temperature adjustment accuracy ± 0.1 ℃;

5. Number of channels: each instrument includes 9 detection channels;

6. Magnetic mixing system: provide long-term mixing;

7. Data output system: use special software for computer processing, LCD display;

8. Automatic liquid level control: it can replenish water by itself to prevent dry burning;

 

Product principle:

The actual biological oxygen consumption of the sample is measured by measuring the charge movement. The ratio of the actual oxygen consumption to the theoretical oxygen consumption is used to determine the biodegradability of the sample.

Typical cases

This is the experimental result of determining the biodegradability of a sample by using the T9000 hydroponic biodegradation instrument and referring to the method standard of GB/T19276.1-2003. The test period is 59 days. At the end of the test, the degradation rate of cellulose is 89.53%, and the curve of various product groups is flat, and the growth is basically over. The experimental design and experimental results are as follows:
