Vacuum Technology: Why Use a Conical v. Straight Reducer? Conductance.
This is a re-post of a “Tech Talk” Article originally posted by Garrett Hanrahan of ANCORP. What advantage does a conical reducer offer compared to a similarly flanged straight reducer? The answer is simple: Conductance! Over the same length, a
Vacuum Technology: To EP or Not to EP?
This is a Re-Post of Blog article by Garrett Hanrahan of ANCORP Before you determine whether or not to specify an EP (electropolish) finish on a custom-fabricated vacuum component or chamber, it helps to know what electropolishing can and cannot
