The invention provides a device for growing cells—referred to as a cassette. The cell culturing device includes a housing that contains a lid having an optically clear window; a fluid distribution channel; a sample injection port fluidically connected to the fluid distribution channel; a base housing a porous media pad; and a media injection port fluidically connected to the media pad. The lid mates to the base to form a sterile seal; the fluid distribution channel is disposed over the media pad, which is viewable through the optical window; and sample fluid introduced into the fluid distribution channel is distributed evenly to the media pad, e.g., via a plurality of channels. The invention also provides kits that include cassettes of the invention and a tube set.

Compositions, devices and processes related to etching of a very thin layer or fine particles of a metal are disclosed for monitoring a variety of parameters, such as time, temperature, time-temperature, thawing, freezing, microwave, humidity, ionizing radiation, sterilization and chemicals. These devices have capabilities of producing a long and sharp induction period of an irreversible visual change. The devices are composed of an indicator comprising a very thin layer of a metal and an activator, e.g., a reactant, such as water, water vapor, an acid, a base, oxidizing agent or their precursors, which is capable of reacting with the said indicator. Ink formulations composed of a metal powder and a proper activator can be used for monitoring several sterilization processes, such as sterilization with steam. When water is used as an activator, a thin layer of metals, such as that of aluminum can be used as steam sterilization or humidity indicator.

Method for treating a service water supply unit of a dental treatment unit, wherein the method has the following sequence of treatment steps: cleaning the service water supply unit using a cleaning agent, preferably a cleaning liquid or a cleaning foam; disinfecting the service water supply unit using a disinfecting agent, preferably a disinfecting liquid.

A method for detecting and/or identifying at least one target microorganism present on a surface, including the following steps: a) depositing, on the surface, a composition including a synthetic, water-soluble film-forming polymer, the composition being a liquid and/or viscous composition or a foam composition; b) drying the composition in order to allow the formation of a polymer film, c) removing, from the surface, the polymer film including the at least one target microorganism; d) dissolving the polymer film with an aqueous diluent in order to form a solution including the at least one microorganism, e) detecting and/or identifying the at least one target microorganism in all or part of the solution, using at least one detection means.
