German Wehrmacht Prüfröhrchen 1 Schwarzer Ring, Gas Tube Detector Single Black, Empty.

These tubes are used to detect and identify hydrogen cyanide and similar compounds. They were contained in a metal box with ten of each, or in an smaller tins, see different photos. Were used with the Hand Gas Detector Pump, Gasanzeiger, Saugpumpe mit Pumpenhalter and other more complicated devices installed in bunkers.
