II. Product Features

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

2. No need to dilute the sample: The maximum detection limit can reach 10,000 mg.

3. Continuous electrolytic oxygen generation: Each bottle of electrolyte can provide several years of electrolytic oxygen; simply add fresh electrolyte once the current electrolyte is depleted to continue use.

4. Precise temperature control: Air-bath temperature control with a set temperature range of 5–90℃ and a temperature adjustment accuracy of ±0.1℃.

5. Number of channels: Each instrument includes 24 detection channels;

6. Magnetic stirring system: Provides long-term stirring;

7. Data output system: Processed by dedicated software on a computer, with an LCD display;

III. Product Principle

Microorganisms consume the oxygen in the culture flask, producing carbon dioxide. The calcium oxide absorbs this carbon dioxide, causing the pressure inside the culture flask to decrease. This pressure difference between the two sides of the pressure gauge triggers the electrolytic circuit to close. As a result, the copper sulfate solution in the electrolytic cell undergoes electrolysis, generating oxygen that is replenished into the culture flask, gradually restoring the flask’s pressure to its initial level. The amount of electric charge passed into the electrolytic cell is directly proportional to the amount of oxygen produced; a coulometer accurately monitors the electric charge flowing into the electrolytic cell. Thus, the oxygen consumption can be calculated, and the ratio of actual oxygen consumption to theoretical oxygen consumption represents the biodegradation rate of the test sample.
