Photobioreactor kit

Cultivation systems for microalgae, cyanobacteria and other photosynthetic microorganisms: the kit brings automated control of light intensity, photoperiod, wavelength, temperature, pH, gas composition, aeration and mixing to the Biobook. Available in airlift or stirred-tank configuration, from 0.5 to 12 L total volume.

/// Highlights

Light becomes a process parameter

Programmable light profiles

Bioflex™ setpoint editor: for every LED channel you set the intensity over time, with static or dynamic profiles, ramp slope and repeated cycles.

Predictable light, repeatable results

Experimental characterization of the red, green and blue channels: PPFD grows linearly with the set intensity, so every setpoint delivers a predictable light dose. As a first approximation, total PPFD = 3.40 × R% + 3.08 × G% + 4.18 × B% (µmol·m⁻²·s⁻¹).

Photobioreactor specifications

The key parts of the system and their specifications. Full details are in the datasheet.

Stirred-tank or airlift
Mechanical mixing with an impeller for robust, high-density cultures, or pneumatic mixing, with very low shear, for delicate microalgae and cyanobacteria.
pH and gas under control
Automatic pH control through acid/base addition or CO₂; gas lines for air, CO₂, O₂ and N₂.
Borosilicate glass vessel
From 0.5 to 12 L total volume; temperature from 2 to 70 °C with automatic closed-loop control.
Programmable multichannel LEDs
Independently controlled RGB and white channels, 13 available wavelengths and white from 3000 to 5700 K; the integrated PAR sensor measures light from 0 to 2500 µmol/m²·s.
