The Stratus is uniquely designed for Microbial Growth Curve Measurements

Product Description

The Stratus plate reader is small enough to fit in the palm of your hand and allows for measurement collection in small spaces, on shared or modular benchtops, and even in restrictive environments, like anaerobic or microaerophilic chambers and incubators.

Its uniquely simple, standalone interface and on-board data storage allow it to be placed anywhere, with or without a computer.

Overall, the Stratus exploits the best of modern technology to reduce labor and allow you to spend your efforts where they matter most. Cerillo has been uncompromising in the Stratus’s design and performance; all that’s left is for you to try it yourself.
