How it Works
algae reactor
Biosecure disconnects make inoculation from starter algae cultures (2 x 20L) simple & clean.
Scale up
The PBR automatically adds water & nutrients as it scales up the culture over 7-10 days.
Algae reactor
The PBR automatically harvests in continuous or semi-continuous mode for months at a time. At any point the entire batch can be harvested.
Algae bioreactor
Between batches run the automated chemical CIP cycle to clean & sterilize the PBR. After a few hours the reactor is ready to be re-inoculated.
