Question

Accepted Answer

Answers to questions related to vacuum technology and design.

Vacuum is a space devoid of matter. Outgassing is the release of trapped gases from a material in a vacuum.
Considerations for designing a vacuum chamber include material selection, sealing methods, and pumping speed.
A virtual leak is a false indication of a leak caused by gas trapped in a chamber or system.
Virtual leak and outgassing are not the same.
Venting is the process of releasing gas from a chamber or system to the atmosphere.
Purging is the process of replacing gas in a chamber or system with a different gas.
A gas delivery system is needed to introduce gas into a vacuum chamber or system.
DC voltages for MFC, valves, etc. vary depending on the specific component and application.
