Virtual Leaks And Why They Matter

A virtual leak is a gas source that is trapped physically in a chamber. Therefore, the trapped gas pocket’s path that goes into the chamber proper becomes small and low conductance. Virtual leaks often occur due to lack of abiding by the correct vacuum practice or a manufacturing fault in the material. There are various types of virtual leaks. For instance, an internal weld crack. If there is air being released, the gas in the crack will leave the crack...

Considerations When Using Grease in a Vacuum System

There are many considerations when utilizing grease within a vacuum system. Often grease is used for the lubrication of o-rings, mechanical components, and in some cases to prevent corrosion. However, it is highly recommended to consider whether a grease is even necessary for each application. The presence of grease within a vacuum system can increase the gas load on the system and can be a source of collecting foreign debris.
