Common Expressions: hermetically
| Expressions | Definition | ||
| Hermetically sealed | The term hermetically sealed is used to describe something that has an airtight seal. The term is often used to describe electronic parts that are designed and intended to be secure against the entry of microorganisms and to maintain the safety and quality of their contents. Applications include thermostats, optical devices, switches, and other devices. The food, chemical, and medical industries all have applications for the use of such "airtight" packaging, as well. High-end coffins, too, are often made to be "hermetically sealed," and must be of metal, or of other material with metal lining, and constructed so that when closed and fastened the coffin is completely airtight.
