Digital photograph of a diathermy set in a purple velvet-lined case. The case has been opened to show the glass vacuum electrodes inside. A ruler has been placed on the gray counter in front of the case for size comparison.
A diathermy set in a portable black leatherette case. The set is missing some of the original instruments. The purple-velvet lined case is fitted with metal instrument clips, which hold: 1) fifteen high frequency glass vacuum electrodes, each fitted at one end with a metal collar, 2) an unidentified glass vacuum electrode with metal collars on both ends, and 3) a nasal glass vacuum electrode mounted on a cork stopper attachment. The case is in fair condition, but the glass electrodes are in good condition.
