Manometric respiration test

Microorganisms consume oxygen (O2) and produce carbon dioxide (CO2) as they metabolize the test substance in closed bottle systems. The CO2 is absorbed using an absorber, resulting in a pressure change within the system that can be used to infer biodegradation.

Material homogeneity

Homogeneous materials have a uniform composition throughout and cannot be mechanically separated into different materials.

Microcosms

Model test systems holding up to several hundred liters, designed to best mimic the complexity of real aquatic ecosystems. The systems are intended to help close the gap between laboratory experiments and reality.
