Water-based formulations comprising an indicating composition dispersed in water are described. The water-based indicating compositions include an organic Bi(III) compound, a sulfur source, and a carbonate salt. Formulations further including a resin and/or an acidic additive are also described.

Water-based organic bismuth, elemental sulfur and lithium carbonate sterilization indicator composition

A chemical indicator composition comprising a bismuth (III) compound selected from the group consisting of bismuth (III) oxide and a bismuth (III) compound comprising at least one organic group which includes 2 to 20 carbon atoms; elemental sulfur; and a compound which makes the composition alkaline when exposed to water vapor at an elevated temperature; a chemical indicator composition comprising a bismuth (III) compound; elemental sulfur; a compound which makes the composition alkaline when exposed to water vapor at an elevated temperature; and at least one acid other than any acid present in the bismuth (III) compound; a chemical indicator comprising a substrate and the composition coated on at least a portion of a major surface of the substrate; methods of making the chemical indicator; and methods of using the chemical indicator are disclosed.

Chemical indicator composition, indicators and methods

A sterilization process challenge device comprising a solid body comprised of walls which define a space, wherein the space can fully contain a sterilization indicator and a volume of gas of at least 5 cubic centimeters and not more than 1000 cubic centimeters; a flow restrictor associated with the solid body such that any flow of the gas out of the space and any flow of a sterilant into the space is restricted; wherein the sterilization indicator indicates whether or not it has been contacted by the sterilant for a time and at a temperature sufficient to sterilize an article; and wherein the walls of the solid body are impervious to the sterilant and have a thickness of at least 0.3 centimeter, methods of using the device and a kit including the device are disclosed.

Sterilization process challenge device

An electronic system for tracking and monitoring articles to be subjected to a sterilization cycle is disclosed. The method uses a sterilization indicator and electronically links sterilization information with the articles subjected to the sterilization process. The indicator allows a sterilization cycle to be monitored without the need for a user to subjectively distinguish between color, quality or intensity of display patterns.

Electronic system for tracking and monitoring articles to be sterilized and associated method

A sterilization indicator having sterilizing agent sensitive indicia is described. The indicator allows a sterilization cycle to be monitored without the need for a user to subjectively distinguish between color, quality or intensity of display patterns.

Machine readable sterilization indicator for monitoring articles to be sterilized

A electronic system for tracking and monitoring articles to be subjected to a sterilization cycle is disclosed. The method uses a sterilization indicator and electronically links sterilization information with the articles subjected to the sterilization process. The indicator allows a sterilization cycle to be monitored without the need for a user to subjectively distinguish between color, quality or intensity of display patterns.
