An embodiment relates to a hose device for a breathing apparatus, characterized by at least one electric line () and at least one pressure line () within the open-cross-section of the hose device ().

Hose device for a breathing apparatus

Composition, method and kit of parts for a simplified and safe extraction of nucleic acids from biological samples, such as crude and processed food, and subsequent analysis by polymerase chain reaction to the presence of animal material, genetically modified organisms, allergens and pathogens. The method comprises the addition of extracting composition together with hot water for extraction and stabilization of nucleic acids as well as removal of substances interfering with DNA polymerase activity.

Test kit for the detection of an analyte in an aqueous solution, including chromatographic test strips for a hapten-antihapten complex and first and second standardized vessels for receiving and positioning test strips, which include first and second hapten-coupled receptors against the analyte dried onto the interior wall for the formation of the hapten-antihapten complex, where a portion of the standardized vessels further include a known amount of analyte embedded in a glass-like layer of trehalose, which are dried onto the interior wall of the control vessel so that they dissolve during reaction of the sample with the hapten-coupled receptors. Through this standardization, analytes in unknown samples may be safely detected by immunochromatography within minutes through a hapten-antihapten complex.

Detection of an analyte in aqueous media

Method for the quantitative determination of vitamins, amino acids, or other substances necessary for life, in a substance mixture, whereby in the culture container, the cavities of a microtitration plate, in each case a predetermined number of vital cells of a suitable microorganism are prepared in a permanent manner. For this purpose, the cells are shock frozen at &#x2212;80&#xb0; C. and then freeze dried in a freezing solution containing 200 to 500 mM trehalose/sucrose. The freezing solution is preferably the test medium. The culture containers are preferably the wells of a microtitration plate.

A coupling for a compressed gas cylinder () includes a separate coupling part () that can be screwed to the standardized fitting () on the cylinder valve (). The connection to the coupling means () of a pressure reducer () or the like is provided by plug-and-socket-type connecting means that can be plugged into each other, interlocked, and closed off by means of locking elements to prevent contamination from outside, the locking element provided on the coupling part at the same time forming a blow-off protection that allows only a limited gas flow when the cylinder valve is opened in uncoupled condition.

In a respirator mask in which the visor panels can be covered by light-absorbing supplementary panels, first and second snap-in hooks are molded onto opposite sides of the visor panel and a stop is molded onto a corner section to form a guide pocket. The outer contour lines and the convexity of the visor panel and the supplementary panel are identical. To attach the flexurally elastic supplementary panel, it is first fastened in the guide pocket and on the first snap-in hook. Then the opposite side is locked into the second snap-in hook after flexing the supplementary panel.
