GärOnA
Fully Automated Fermentation Test System for Biogas Research

Product description
Meaningful fermentation tests are essential for efficient biogas production. Through these tests, the microbiological processes and degradation characteristics of new substrates can be described and optimized. The procedures for fermentation tests are specified, among others, in the VDI Guideline 4630.
With the GärOnA system, both batch and continuous fermentation tests can now be carried out fully automatically.
The system minimizes the pressure range in the fermentation vessels, positively influencing the solubility equilibrium of methane, carbon dioxide, and other gas components in the liquid phase.
During depressurization, a biogas sample from a vessel is automatically fed to a gas chromatograph for detailed analysis. This setup enables precise tracking of methane production changes and the time course of methane formation rates.
The fully automated GärOnA laboratory system makes it exceptionally easy to conduct exact and high-content investigations of anaerobic digestion processes, providing comprehensive, high-quality data for biogas research and substrate development.
