Abstract: The invention relates to a sterilization testing device comprised of a housing with a test chamber, an indicator placed therein, and with a supply for supplying the sterilization medium. According to the invention, the sterilization testing device consists of at least two housing parts that are matched to one another. A supply channel is made inside the housing part and serves to supply the sterilization medium. The supply channel is configured in such a manner that it forms the base body of the test chamber. The test chamber accommodates the indicator that indicates the completion of the sterilization process. Alternatively to this solution, the invention provides a variant, which is very effective with regard to manufacturing and which permits a quantitative statement regarding the sterilization. Webs are formed inside the housing in the at least partially meandering and/or spiral configuration of the supply channel. These webs, together with, at least in part, the lateral part(s) of the housing parts form a portion of the supply channel. A supply channel formed in this manner accommodates the indicator.

Abstract: Methods, processes and compositions are provided for a visual or chemochromic hydrogen-detector with variable or tunable reversible color change. The working temperature range for the hydrogen detector is from minus 100° C. to plus 500° C. A hydrogen-sensitive pigment, including, but not limited to, oxides, hydroxides and polyoxo-compounds of tungsten, molybdenum, vanadium, chromium and combinations thereof, is combined with nano-sized metal activator particles and preferably, coated on a porous or woven substrate. In the presence of hydrogen, the composition rapidly changes its color from white or light-gray or light-tan to dark gray, navy-blue or black depending on the exposure time and hydrogen concentration in the medium. After hydrogen exposure ceases, the original color of the hydrogen-sensitive pigment is restored, and the visual hydrogen detector can be used repeatedly. By changing the composition of the hydrogen-sensitive pigment, the time required for its complete regeneration is varied from a few seconds to several days.

Abstract: An aqueous solution is formed by dissolving a dye made of alizarin and a humectant made of glycerin, and alkalized by dissolving a base (alkaline substance), thereby preparing a detector solution (101) in which the content of the humectant is about 20 wt %. An impregnated carrier (104) impregnated with the detector solution (101) is formed by dipping for 30 sec a sheet-like carrier (103) made of cellulose filter paper in the detector solution (101) so that the carrier (103) is impregnated with the detector solution (101). The impregnated carrier (104) is pulled up from the detector solution (101), and dried in dry nitrogen by evaporating a solvent such as water contained in the impregnated carrier (104), thereby forming an ozone detecting device (105).
