Use the interconnectivity of sensors (CGQ) and actuators (LIS) within the new DOTS Software to enable feedback controlled feeding in your shake flask experiments. Set up your injection strategy based on your biomass threshold or growth rate and start feeding based on the specific needs of your culture.

What Our Customers Are Saying
"Overall, the LIS system is easy to assemble, reduces manual work significantly, and allows us to test multiple feeding profiles, including linear and exponential feeding.”

"LIS- and CGQ-system turns nights and weekends into productive times for the preparation of optimal inocula and for the first time leverages the early stages of culture expansion to a level of bioprocess monitoring and control that has until today only been accessible in later stage stirred tank bioreactors.”

With the DOTS platform I can combine sensors and actuators in a simple way to perform completely new applications like biomass-based feeding in shake flasks. My shake flasks can now operate similar to small-scale bioreactors, keeping the ease and cost-effectiveness of flasks but adding the sensor and control options of bioreactors. This is truly revolutionary for me and my experiments.

Customer Success Stories
With LIS, typical bioreactor processes, like fed-batch cultivations, can be recreated in shake flasks
Fed-batch cultures support the growth of S. cerevisiae on potato waste because the concentration of growth inhibitors in the medium can be controlled. With the Liquid Injection System (LIS), these process conditions could be imitated on a shake flask level.
