Plastics Compost Biodegradation Respirometer GBDA-120 Compost Degradation Tester is designed in full compliance with standards such as IS014855-l and ASTM D5338. The mass of carbon dioxide released during biodegradation can be detected automatically, and the biodegradation percentage of degradable materials can be determined. Test principle The test material and inoculum are mixed and poured into the reaction vessel. Under the condition of aerobic composting, the organic compounds of the test materials are decomposed by microorganisms into carbon dioxide (C02), water (H20) and the mineralized inorganic salts and new substances of the elements contained in them, and the emitted carbon dioxide (C02) is measured by a continuous infrared analysis sensor (C02) to determine the final biodegradability of the test material.
