Z150 Photobioreactor

The Z150 Photobioreactor is used for precise phototrophic cultivation of algae and cyanobacteria. It features a unique combination of the cultivator and monitoring device. Light intensity and timing, spectral composition, temperature can be set with high accuracy.

Cultivation conditions of a photobioreactor can be varied according to  user- defined protocol. The growth of the algal culture is monitored by the integrated densitometer (OD 735, OD680). Chlorophyll content of the culture can also be monitored continuously by the difference of optical densities at 680 and 735 nm. The instantaneous physiological state of the culture is measured by the Photosystem II quantum yield Fv/Fm.

For cultivation of up to 8 different algal cultures please see the Z160 Multicultivator.
