    Brief

    Helsingin yliopisto needs a multi-unit (minimum 8 units), ideally rack-mounted photo-bioreactor (PBR) system for closed, biosecure cultivation of macroalgae gametophytes and sporophytes, with capacity for microalgae culture, over a period of 6 months. Each unit must provide independent closed-loop control of temperature, pH, and LED light spectrum/intensity, enabling parallel climate-stress treatments, alongside biosecure fragmentation, low-shear circulation, and fine-particle filtration. A centralized controller must allow monitoring and logging across all units while preserving independent control per unit. The system will support climate-impact research on harvested seaweed species, including thermal performance and stress-response trials. The award criteria are Price (40%) and Quality (60%), with Quality encompassing After-Sales Service and Technical Support, Technical Functionality and Performance, and Equipment Scale and Fit for Purpose.

    From the notice

    • A multi-unit (minimum 8 units), ideally rack-mounted photo-bioreactor (PBR) system for closed, biosecure cultivation of macroalgae gametophytes and sporophytes propagated by fragmentation, with capacity to also support microalgae culture. Each unit must provide independent closed-loop control of temperature, pH, and LED light spectrum/intensity, enabling parallel climate-stress treatments (e.g., simulated heatwave vs. ambient baseline) on the same rack footprint, alongside biosecure fragmentation, low-shear circulation, and fine-particle filtration to prevent contamination. A centralized controller must allow monitoring and logging across all units while preserving independent control per unit. The system will support climate-impact research on harvested seaweed species, including thermal performance and stress-response trials.
