SteriSense®

Electronic Bowie Dick Test

The Bowie Dick test, also referred to as an air removal test or steam penetration test, is used for daily routine control of steam sterilizers (autoclaves) to verify that they perform in accordance with ISO 17665.

A safe and reliable test is important to use, as proper air removal is crucial for the performance of the steam sterilizer. Any air left in the sterilizer can impact how the steam penetrates the load and thereby the sterilization of the instruments. The Bowie Dick test is commonly used in Central Sterile Services Departments (CSSD) as part of the daily morning routine before releasing the steam sterilizer for use.

 

Peace of mind with SteriSense

SteriSense is a brand new and innovative Electronic Bowie Dick Test (air removal test) that is unmatched in accuracy, performance and reliability. Our Bowie Dick test provides far more insight into critical sterilization parameters than previously possible, ensuring patient safety. Unlike traditional chemical indicators, where you subjectively decide according to a change in color, SteriSense also offers an accurate report that eliminates any guess work.

The ValSuite® Software

SteriSense is extremely easy to use and requires only little training to operate. With just a single click in the software, the SteriSense measuring device will start to measure and record data. Once the Bowie Dick Test Program has ended, the device is simply placed back in the reader station where the software automatically processes the data and provides a test result.

All test results are saved electronically and can be presented in accessible reports with audit trails – simple and easy!

When compared to traditional methods, the SteriSense provides far more insight into critical sterilization parameters than previously possible. The standard report showcases all the results from the optional ‘checks’ performed by the software. When using the standard settings, a routine control test will be performed in accordance with EN ISO 17665.

SteriSense has been tested by a 3rd party certified test institute to comply with the reference method originally developed by Dr. J. Bowie and J. Dick, using a test procedure described in EN ISO 11140-4.
