RoboLector Platform

The RoboLector XT system is an automated fermentation platform which combines the high-throughput fermentation and online monitoring capability of the BioLector XT microbioreactor with the precise and accurate liquid handling of a robotic system.

The RoboLector system autonomously prepares media compositions, among others, from the design of experiments (DoE) tests, followed by an online-monitored high-throughput cultivation.

Furthermore, pH adjustments can be made and inducers as well as feed solutions can be added to each cultivation well according to a pre-defined schedule or triggered by online process signals. Automated sampling into various targets including a cooling station facilitates optimal process monitoring and control.
