I'm reasonably certain tht the photos show fermentation vessels and related gear. I have used such to grow non-military bugs containing mammalian genes. The stuff shown looks a lot like the (now) old-fashioned stuff I used in the '80s. Probably not of American (Brunswick) manufacture -- more like European (e.g., French)...
I also remember the UN poo-pooing the idea that they were capable of producing bio-weapons agents.
