The Manometric Respirometer is a classical manometric system for aerobic processes (BOD5, ISO 5815-2, OECD 301F, SM 5210 D), aerobic soil respiration (ISO 16072) and anaerobic/anoxic processes. Versions for bioplastic biodegradability studies are also available both in aerobic (ISO 14851 - aerobic biodegradation of plastic materials in an aqueous system, ISO 17556 - ultimate aerobic biodegradation of plastic materials in soil, ISO 18830 - aerobic biodegradation of non-floating plastic materials in a seawater/sandy sediment interface, ISO 23977-2 - aerobic biodegradation of plastic materials exposed to seawater) and anaerobic conditions (ISO 14853 - anaerobic biodegradation of plastic materials in an aqueous system, ISO 13975 - anaerobic biodegradation of plastic materials in controlled slurry digestion systems).
