Project Description


Easy fermentation in lab scale with biomass monitoring

  • Fast self-adapting regulation
  • Integrate biomass monitoring
  • Flexible culture vessels
  • Single or multi channelled fermentation


EloFerm is a compact benchtop fermenter including all features necessary for cultivation. As a special advantage EloFerm even features highly precise biomass monitoring. The state-of-the-art control software is very user-friendly and provides various ways of measuring, storing, viewing, comparing and exporting series of cultivation data. EloFerm comes with an implemented inline-photometer for continuous measurement of optical densities, this way e.g. OD thresholds can be set for an automatic alarm signal.
