Where can i buy a photobioreactor used for growing algae?

Question

something small is best

Answer 1

I can easily make one for you. What quantity of algae are you needing to grow per day? What species? Do you need growth media? What exactly are you trying to accomplish?

How small? For what purpose will it be used? If for research or R&D, we need to talk. As a guy who has been personally working on the development of a PBR with a solar efficiency of over 150% and a pump that doesn't scar the culture. A continuous, size selective, algae de-watering harvester was also called for. A pain in the butt to figure that one out.

I can help shorten your learning curve by a lot.

Answer 2

This is typically something you would build yourself.

Bioreactors are typically used to support cell culturing when very controlled environmental conditions are needed.  Algae do not need a highly controlled environment.  They're pretty happy with just a pool of water and sunshine.
