The BacT/ALERT® 3D Dual-T apparatus was designed for users who need to perform rapid and easy product control. Performing non-destructive, dual-temperature microbial detection, this alternative system offers its users the most reliable results.

Automation Meets Tradition

The BacT/ALERT® Dual-T apparatus represents the automation of a traditional method : after injecting culture media bottles with a given sample, users only need to load the bottles into their system. Both the incubation and reading phases are automatically and objectively performed :

innovative method for microbial detection & sterility testing

    • Simplified testing process
    • Reduced “hands-on” time and labor costs


    Designed with our own patented colorimetric technology, this growth-based system can detect within 24-72 hours an extremely large range of organisms, such as aerobic, anaerobic, facultative microorganisms, yeast and fungi.


    The dual-temperature feature of this system guarantees a complete coverage of growth conditions – and is compliant with the different pharmacopoeias - allowing to conduct microbial detection at both 32.5°C and 22.5°C.

    To ensure accurate results’ traceability, we provide you with a 21 CFR Part 11-compliant data management system. Depending on your microbial testing needs, we offer the possibility to choose the most appropriate system among three different options : Signature, Select and Select Link (find out more in our e-catalogue)

    bioMérieux also offers a wide range of BacT-ALERT® 3D Dual-T culture media bottles, adapted to the type of microbial detection performed.
