  • Patent number: 11965150
    Abstract: A method is provided for vaporized hydrogen peroxide cleaning of a chamber. The method includes altering a temperature of air in the chamber from an initial temperature to a sterilization temperature over a first time period. The method also includes injecting vaporized hydrogen peroxide into air in the chamber to alter a relative humidity of hydrogen peroxide vapor in the chamber to a sterilization level over the first time period. The method also includes maintaining the temperature at the sterilization temperature and the relative humidity at the sterilization level over a second time period. The method also includes reducing the relative humidity from the sterilization level to a safe level over a third time period. In one embodiment, the method is provided for vaporized hydrogen peroxide cleaning of an interior chamber of an incubation container. In other embodiments, the incubation chamber featured in the method is provided.

  • Publication number: 20240002255
    Abstract: A water treatment system for supplying water for use in humidifying a chamber. A system piping circuit carries water with a desired H2O2 concentration and comprises a plurality of controllable valves to determine water flow paths through the piping circuit, thereby subjecting the water to one or more treatment processes. A holding reservoir receives intake water from one or more water sources and also receives H2O2. A pump is activated by a control system to supply the H2O2 from a source into the holding reservoir. The control system activates the pump according to a predetermined schedule or according to a measured concentration of H2O2 in the piping circuit, as measured by certain system sensors. An H2O2 neutralizing device neutralizes the H2O2 in the water prior to supplying the water to humidification components to humidify the chamber.

  • Publication number: 20230416116
    Abstract: A system for providing conditioned water. A holding reservoir receives intake water, of unknown quality, from a water source and a pump pressurizes the system. Water flow paths through the system are controller by opening and closing a plurality of controllable valves. A sensor measures the water quality of the water in the holding reservoir and produces a signal representative of the measured water quality. A microprocessor receives the signal, compares the measured water quality with a desired water quality range, and produces conditioned water by controlling valves to deionize the water or to ionize the water, as needed. An output valve controls outflow of the conditioned water to a humidification or environmental chamber for humidifying the chamber.

  • Patent number: 11150014
    Abstract: An insulated chamber having an interior region for storing items therein includes a phase change material to facilitate controlling the temperature of the interior region and the items. A heating device or cooling device may be used to melt or freeze the phase change material. The phase change material (PCM) may be in various locations such as the walls of the chamber in the form of packets or in the form of containers that serve as shelves and may be removable from the interior region. The packets may have recesses for receiving the items. The phase change material may be within capsules that may be within a liquid or a solid matrix. Controls may be provided to control humidity, oxygen, and carbon dioxide within the interior chamber.

  • Publication number: 20200360552
    Abstract: A method is provided for reducing a duration of an inactivate step of a decontamination process of contents within a chamber of a container. The method includes at least one of directing air in contact with a catalyst to reduce a level of hydrogen peroxide (H2O2) in the air during the inactivate step and/or altering a temperature of air within the chamber during the inactivate step. A system is also provided for performing one or more steps of the method. The system includes the container defining the chamber; the catalyst; a component configured to direct air through the catalyst; and a processor configured to cause components of the system to perform one or more steps of the method.
