摘要

A method is described by which glass capillary leaks with extremely small flow rates can be easily and rapidly produced. The predictability of these leak rates is determined by the resolution of the optical system used in measurement of bore diameter. Data are given which will allow construction of such leaks. A manifold of leaks is described which will introduce gas into a high‐vacuum system at several different fixed leak rates. It contains no moving parts or high vapor pressure material on the high‐vacuum side, yet the leak rates can be manipulated over a wide range. The characteristic features of these leaks are shown to be reasonable in light of well established theory.
