Microbioreactor for high-throughput fermentations with the online monitoring of biomass, pH, DO, and fluorescences.

The BioLector I measures the most common fermentation parameters online while running a cultivation. Additionally, the bench top microbioreactor controls the shaking speed, the temperature inside the cultivation chamber, and the humidity.

Product Info

Real time culture monitoring on a parallel scale


Working Principle

The micro fermentation system is based on standard disposable microtiter plate formats and operates with non-invasive, optical sensors. Due to the continuous and rigorous shaking during the optical measurements and during the entire experiment, it is ideally suited for aerobic and anaerobic cultures.

Optional Modules

If a high or very low oxygen level is required, the system can be easily upgraded with additional modules, for example for CO2-enriched aeration, or anaerobic conditions.

By adding one of these modules the microbioreactor maintains all existing basic features. An upgrade with multiple modules in one system is possible.

///  Gas Modules

  • O2 up regulating module for the up-regulation of oxygen up to 35 %
  • O2 down regulating module for the down-regulation of oxygen down to 2 %
  • CO2 up regulating module for fermentation with a CO2-controlled gas atmosphere
  • Anaerobic cultivation set for cultivating under anaerobic conditions

///  Fluorescence Modules

  • LED / filter module for fluorescence measurements for wavelengths between 365 nm - 800 nm.

Up to three additional fluorescence modules can be added; in total, six different ones fit into the system.


Automated Fermentation

For fully-automated high-throughput cultivations, the BioLector will be combined with a liquid handling robotic system. Learn more about the RoboLector
