Hermetic seal

Under a hermetic closure is understood in the laboratory and chemical engineering, physics, and in apparatus an absolutely tight, especially an exchange of air or water preventing completion.

Hermetic sealing is referred to as the process of sealing in order to prevent exchange of matter. The term is derived (see Hermetic ) historically Hermes Trismegistus.

With a hermetic seal can be, for example, make watertight equipment to dry chemicals. Similarly, one could come up with a corresponding closing a vacuum hold. Other examples of hermetically sealed systems are heat pumps and chillers. To avoid slightest contamination of the medium through air or water which affect the function, or a (eg environmentally harmful ) outflow of the medium, such systems must be absolutely tight with respect to exchange of matter.
