steristen

Steristen is a brand of sterilization indicator strips used in healthcare settings to monitor the effectiveness of sterilization processes. These indicators are designed to change color when exposed to specific conditions that indicate successful sterilization, such as high temperature and steam. Steristen strips are typically used in steam sterilization (autoclaving) processes, which are common for medical instruments and equipment.

The principle behind Steristen indicators is based on chemical reactions that occur when the indicator material is exposed to the sterilizing agent. When the appropriate temperature, time, and steam penetration are achieved, a chemical compound within the strip undergoes a change, resulting in a visible color shift. This color change serves as a visual confirmation that the sterilization cycle has likely met the required parameters.

It is important to note that Steristen indicators are considered process indicators, not biological indicators. Process indicators provide a general indication of exposure to sterilizing conditions, while biological indicators, which contain hardy microorganisms, are used to definitively prove the killing of all viable organisms. Steristen strips are often used in conjunction with other monitoring methods, such as daily testing of the sterilizer and regular biological monitoring, to ensure comprehensive sterilization assurance. The specific type of Steristen indicator and its intended use should always be confirmed with the manufacturer's instructions.
