I had some suggestions for overall themes for labs. These would also include some additional rooms for the mix.
Major/Overall Themes:
These themes are for an entire lab:
Material Science: Should continue advanced materials being researched at these places. Small rooms around the larger lab with samples of the materials. These rooms would most likely have been analyzing the new materials and trying to come up with new things to make/use them for. This can contain things like harder glass for vehicles, a source for high tech plates, and the like. This would mainly be raw materials and not complex items made from them.
Possible Subthemes: Alien/multidimensional materials: Artifacts and some special materials from the shadow realm?, terrestrial: Home made high tech materials. Weaker then other sources but more plentiful.
Physics/Dimensional Lab: This lab would most likely be the lab that Gordon Freeman worked at. You would find portals, alien creatures, artifacts, and maybe small samples of alien materials and devices.
Possible Subthemes: Extradimensional: Study would concentrate on creating gateway creation. This would include having shadow creature pens and the like.
Chemistry Lab: This lab would concentrate on creating various chemical compounds. Advanced Chemistry books, mutagen, purifier, and royal jelly abound. The ability to make gunpowder might be here.
