The Medical Laboratory appears in Catacombs of The Moon. The set is a revamp of the Life Support/Power Room, with an observation room and a nuclear reactor door. The same set is revamped again in this episode as the Explosives Storeroom.
In all the scenes, the doors to the corridor are open. The Medical Center is the far door seen through the arch, but the sign has been removed. There's a power cable at the base of the wall on the left, leading out into the corridor.
The small room ("Life Support" in other episodes) is seen through the observation window, with a Sorella lamp visible on the desk. Helena's table is a Stadio.
This is one of Bergman's perspex spheres. The computer alcove is seen beyond.
This angle shows the reactor door behind them.
