Shaker tray SENSOLUX® stand-alone version is an intelligent shaker tray with an integrated sensor system. It is used for monitoring pH value and dissolved oxygen (DO) saturation during cultivation of animal and human cells. Used in combination with the new single-use SENSOLUX® Erlenmeyer Flasks, it facilitates the easy, safe and highly informative online and non-invasive measurement of these crucial parameters in incubation shakers. This first member of the SENSOLUX® family is a powerful tool for significant results in the early process development phase, e.g., for advanced clone screening and media optimization.
