A simple point‐contact tunneling device for examination of the properties of almost any metal, alloy, or compound of almost any shape is described. The device has a small mass to permit dipping into liquid helium directly from room temperature. The stability and accuracy of the drive mechanism permit it to be used for single‐particle superconductive tunneling as well as for Josephson devices, weak links, and metal‐metal bridges. Experimental results showing a recording of the drive characteristics of the differential screw, the transition from Josephson weak‐link behavior to single particle tunneling for a Nb&sngbnd;I‐Vycor (Pb) sample, a well‐resolved energy gap for niobium, and the phonon structure of lead are presented.
