ultra low temperature vacuum concentrator for rare earth ore in lesotho

The Fundamentals of High, Ultra  Extreme High Vacuum

The simple fact is that the leak rate should be low enough so that the required operating pressure, gas balance and ultimate pressure in the vacuum container, are not unduly influenced. In terms of HVs, XHVs and UHVs, it is small leaks that are the main cause of concern, and the only credible method to detect leaks smaller than 10 7 mbar.l/s
