A method for validating a method for sterilizing an item, making it possible to validate the sterility assurance level achieved with this sterilization method. The method includes carrying out a first step of contaminating a container receiving the item with more than 10.sup.5 living microorganism cells, then carrying out a first sterilization cycle with the chosen method, then opening the container in order to contaminate it again with more than 10.sup.5 living microorganism cells, then carrying out a second sterilization cycle with the same method, and finally checking the sterility of the container after the first sterilization cycle and after the second sterilization cycle. The method is applicable in particular for products and devices intended for health use.

An aqueous solution for intraoral cleaning via irradiation with ultraviolet ray and/or near-ultraviolet visible ray and/or ray in an 800-900 nm near-infrared region is employed as the hydrogen peroxide aqueous solution, wherein a concentration of hydrogen peroxide is 1 w/v % to 7 w/v %, and a concentration of a hydrogen peroxide stabilizer is 81 ppm (mg/L) or less in the aqueous solution.

Systems, apparatus, and methods are described for a disinfection system formed of a plurality of modular units, wherein each modular unit is (1) coupleable to at least one other modular unit from the plurality of modular units and (2) includes an energy source from a plurality of energy sources. The plurality of energy sources can be configured to provide energy having an intensity capable of disinfecting a surface of the object located in a disinfecting area. The disinfection system can be used with object indicator tags and/or include one or more safety features.

A decontamination system not requiring large-scale equipment such as large-diameter ducts and anti-condensation heaters and for that reason capable of efficiently using a decontamination liquid. Long pipes can be installed for each of a plurality of rooms to be decontaminated, a decontamination liquid is not present in supply pipes as a residual dead liquid, and a proper amount of decontamination liquid can essentially be supplied for each room to cause no failure of an ultrasonic vibrator.

The decontamination system employs a decontamination mist and includes a compressed air generating means and a decontamination liquid supplying means, and each room to be decontaminated is provided with a primary mist generating means and a secondary mist generating means. The conveyance distance of a primary mist supply pipe communicating the primary mist generating means and the secondary mist generating means is longer than the conveyance distance of a decontamination liquid supply pipe communicating the decontamination liquid supplying means and the primary mist generating means.

Even when the filling speed increases, the surface temperature of a molded bottle falls within a constant range, and a sterilizer adequately sterilizes the bottle.

A preform is heated, the heated preform is sealed in a mold, the preform sealed in the mold is blow-molded into a bottle, the surface temperatures of a neck portion, a body portion, and a bottom portion of the molded bottle are measured, and the mold temperatures of a neck portion, a body portion, and a bottom portion of the mold is so adjusted that the measured surface temperature of the bottle falls within a specified temperature range.

The present disclosure provides decontamination system that includes a decontamination chamber for sealably holding one or more items for decontamination. The system also includes a decontamination unit comprising: a controllable air heater and humidity control unit to controllably heat an ambient air source and to control a temperature and humidity of air within a decontamination chamber; a controllable vaporizer unit to controllably vaporize one or more decontamination agents by combining the controllably heated ambient air with the one or more decontamination agents; and controller circuitry to control a controllable air heater and humidity control unit to heat the ambient air to a selected level, and to maintain a selected heat and humidity within the decontamination chamber, and to control the controllable vaporizer unit to provide a selected flow rate of the one or more decontamination agents into the decontamination chamber.

A sterilization machine for the sterilization of caps, comprising an isolation chamber having an inner space in which the caps are advanced along a conveying path and separating the inner space from an outer space, a plurality of carts positioned within the inner space and an actuation unit arranged in the outer space and configured to selectively advance the carts along an advancement path by means of the generation of an electromagnetic field. Each cart comprises a pusher element configured to interact with a group of caps having one or more caps, to advance the respective group along the conveying path during the advancement of the respective cart along at least one portion of the advancement path. The actuation unit is configured to selectively lift the carts by means of levitation and to advance the carts along the advancement path by means of control of the electromagnetic field.

A sanitizing system for use in a laundry treating appliance and at least partially included in an agitator of the laundry treating appliance, the agitator may include a housing configured to be removably attached to a rotating drum or an impeller of laundry treating appliance, and an ultraviolet light disposed in the housing, wherein the ultraviolet light is configured to transmit ultraviolet light to articles of clothing disposed in a drum of the washing machine.

An aqueous solution for intraoral cleaning via irradiation with ultraviolet ray and/or near-ultraviolet visible ray and/or ray in an 800-900 nm near-infrared region is employed as the hydrogen peroxide aqueous solution, wherein a concentration of hydrogen peroxide is 1 w/v % to 7 w/v %, and a concentration of a hydrogen peroxide stabilizer is 81 ppm (mg/L) or less in the aqueous solution.

Provided herein are methods and compositions for the reduction of endospore contamination of a substrate with percarboxylic acid-based compositions. The methods can include the step of continuously monitoring the oxidation-reduction potential of the percarboxylic acid-based compositions.
