ExpoSure™ Biological Indicator

Mesa Labs announces the introduction of a new biological indicator (BI), ExpoSure™. The ExpoSure™ BI is a self-contained biological indicator (SCBI) for use in monitoring the efficacy of the following STERRAD® sterilization cycles:

  • STERRAD® 50
  • STERRAD® 100S (Short & Long*)
  • STERRAD® 200 (Short & Long*)
  • STERRAD® NX® (Advanced & Standard)

*”Long” applies to industrial cycles only

ExpoSure has received its 510(k) from the FDA making it suitable for healthcare and non-healthcare settings and usage. Its 24-hour incubation time and flexibility make it a powerful tool to help your facility maintain compliance and patient safety while offering a reliable and robust 12-month expiry.

With 30 indicators per box, ExpoSure is the ideal product for budget-conscious departments looking for an affordable alternative product that delivers high-quality and consistent results.

ExpoSure is a direct replacement product and can be used in conjunction with existing incubators out in the field (55-60 °C). The on-board chemical indicator confirms that it has been exposed by changing from red to blue upon exposure to the sterilant.
