The Time Lab is one of many facilities owned by time traveler Rip Hunter.
Formerly, it was the primary base of operations for his partners the Time Masters. Presently, only Rip utilizes it, though his newest partner Booster Gold occasionally works out of the laboratory as well. The Time Lab also houses Rip's Time Sphere, a device he uses when traveling through time. Rip's most recent Time Lab is located in the middle of the Arizona desert.
