Product principle:

Microorganisms consume oxygen in the culture bottle, produce carbon dioxide, carbon dioxide is absorbed by quicklime, the pressure of the culture bottle is reduced, so that the pressure on both sides of the pressure gauge produces a pressure difference, resulting in the electrolytic circuit connection, the copper sulfate solution in the electrolytic bottle electrolysis produces oxygen, which is added to the culture bottle, so that the pressure in the culture bottle gradually returns to the initial level. The amount of electricity passed into the electrolytic bottle is proportional to the amount of oxygen produced, and the coulombmeter accurately monitors the amount of electricity passed into the electrolytic bottle, so as to calculate the oxygen consumption. The ratio of actual and theoretical oxygen consumption is the biodegradation rate of the test 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:
