Abstract
Abstract Translated from German Ein Prüfröhrchen für brennbare Gase soll mit Schutzvorrichtungen versehen werden, so daß es für den Nachweis von brennbaren Gasen nicht zu einer Zündquelle werden kann. Dazu ist vorgesehen, daß vor und/oder hinter der Reagenzfüllung (10) eine Flammensperre (7, 8) angeordnet ist. A test tube for flammable gases should be provided with protective devices so that it cannot become an ignition source for the detection of flammable gases. For this purpose it is provided that a flame arrester (7, 8) is arranged in front of and / or behind the reagent filling (10).
