Ecto-containment unit

In the Ghostbusters' dimension, the ecto-containment unit is the final repository for the various ghosts and other entities that the Ghostbusters have captured.

In Teenage Mutant Ninja Turtles/Ghostbusters, the containment unit's self-contained power source was used by Egon Spengler and Donatello to construct a dimensional transporter. However, it malfunctioned when they tried to activate the transporter, destabilizing the containment grid and forcing the two scientists to quickly repair it to avoid a massive explosion.

In Teenage Mutant Ninja Turtles/Ghostbusters 2, the two scientists joined forces again in order to entrap the Collectors, which they deduced could only happen if they created a dimensional gateway into the containment unit itself. After some trial and error, they successfully created a gate into the high-powered containment unit, and pulled the Collectors inside.
