AI-assisted summary
Description from the seller
NORISAN High-frequency Apparatus “Violet Ray” – a rare electrotherapy device, Germany, circa 1931–1933
Description
Rare historic high-frequency electrotherapy device NORISAN (Hochfrequenzapparat), produced in Germany by Norisan Apparatebaugesellschaft m.b.H. of Nuremberg, dateable to the early 1930s, probably about 1931–1933.
The device belongs to the category of instruments historically known as “Violet Ray,” used at the time in high-frequency electrotherapy.
The exemplar is in excellent conservational condition and is especially interesting for its completeness. It is preserved in its original briefcase, covered with the distinctive crocodile‑skin finish, with original interior and molded compartment for the device and accessories.
Contents
The lot includes:
* original NORISAN device;
* original handpiece, in excellent condition;
* original set of glass electrodes/accessories;
* original cables;
* original case;
* components and accessories present in the original configuration.
The glass electrodes are intact, without obvious breakage, and the set appears particularly complete.
On the device panel there is a switch for feeding 110–220 V.
Also visible is the configuration for unipolar/bipolar operation, a feature of Norisan devices documented in the German medical literature of the period.
Serial number
25932
The serial number is clearly present on the device.
Historical interest
The type and configuration of this exemplar find interesting comparisons in the historical documentation.
A NORISAN device kept at the Historisches Museum Luzern is dated around 1931 and presents a very similar configuration, including the crocodile-skin case cover.
Furthermore, a German medical publication from 1933 documents a “Hochfrequenzapparat Norisan” with 110/220 V supply, unipolar/bipolar operation, electrode set and case: a configuration particularly coherent with that of this specimen.
These elements make the lot particularly interesting not only as a vintage device, but as a historical instrument of German medical and electrotherapy technology in the 1930s.
Conditions
Excellent conservational condition for its age.
The case shows normal signs of age and use, but the crocodile-skin finish is well preserved. The glass components are intact. The handpiece is in especially good condition.
The device has not been subjected to professional electrical testing and is not guaranteed to be functioning. Given the age of the instrument, it is recommended not to connect it to mains power without prior verification by qualified personnel.
Sold as a collectible historic object, not for medical use.
