Open system

Description

An open system is a system with boundaries that allow external exchange of energy and matter; the surroundings are merely considered as a source or sink for quantities transferred across the system boundaries (external flows, Iext).

Open O2k-Chamber

The term "open O2k-Chamber" refers to a situation in which the liquid phase is allowed to equilibrate with a gas phase. The liquid phase is defined as the system, which is then open for the exchange of oxygen with the gas phase, finally resulting in a stable oxygen signal with a slope over time of zero. Insert the stopper fully, siphon off any liquid from the receptacle of the stopper, and remove the stopper to a position defined by Stopper-Spacer to include an optimum volume of the gas phase obove the stirred liquid phase.
