Two, product features

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

2, no dilution sample: the maximum detection limit can reach 10000 PPM;

3, continuous electrolytic oxygen supply: each bottle of electrolyte can provide several years of electrolytic oxygen, after the electrolyte is used up, add a new electrolyte can be used;

4, precision temperature control: water bath temperature control, temperature setting range of 4-90, temperature adjustment accuracy ±0.1;

5, channel number: each instrument includes 9 detection channels;

6, magnetic stirring system: provide long time stirring;

7, data output system: the use of special software computer processing, LIQUID crystal display;

8, Automatic control of liquid level: it can fill water by itself to prevent dry burning.

 

Three, product principle

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

 

 

Four, technical parameters

 

1. Continuous dynamic oxygen supply system

1.1 Channel: Nine channels were tested at the same time;

1.2 Oxygen supply: generate oxygen by electrolyzing copper sulfate;

1.3 Liquid inside the electrolytic bottle: copper sulfate solution;

1.4 Pressure gauge: sensitivity 9.806Pa, internal copper sulfate solution;

1.5 Mounting frame material: propylene;

1.6 Electrolytic bottle material: hard glass;

1.7 Electrode: Platinum (positive), copper (negative);

1.8 Culture bottle material: high borosilicate hard glass.

 

2. Constant temperature culture system

2.1 Set temperature range: 4-99, step 0.1;

2.2 Temperature control mode: water bath;

2.3 Temperature accuracy: ≤±0.1;

2.4 Culture flask volume 500ml is optional;

2.5 nine channel magnetic stirring system.

 

3. Detection system

3.1 Oxygen consumption detection: the actual oxygen consumption is determined by detecting the charge movement of the electrolytic system;

3.2 Sensitivity: 0.2ppm;

3.3 Measurement range: 0-10000 PPM;

3.4 Temperature probe: Pt100.

 

4. Software control system

4.1 Software control system with independent property rights;

4.2 Software acquisition of data to generate real-time data curve;

4.3 Data output system;

4.4 Bearer system: professional operating system, etc.

4.5 Data storage: It can be saved in the test;

4.6 Cloud platform, data and charts can be accessed and downloaded remotely at any time;

4.7 Usb disk ports: Three.

4.8 LAN Interface: Yes.

 

Five, standard configuration

1. 1 set of host;

2. One set of data processing software;

3. 9 electrolytic bottles (500ml);

4. 9 culture bottles (500ml);

5. 9 air bottles (350ml);

6, absorption bottles (500ml) 9;

7. 9 U-shaped tubes;

8. One set of hose.

 

Six, typical cases

This is the experimental result of measuring the biodegradability of a sample by using T9000 hydroponic biodegradability tester in reference 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%, the curves of each sample group are flat, and the growth is basically over. The experimental design and experimental results are shown as follows:
