Stasis Chamber

A Stasis Chamber is a tank where Test Subjects are "stored" while waiting to be awaken for testing. In the Human Vault located near Test Shaft 02 in the lowest levels of the Aperture Science Enrichment Center and opened by ATLAS and P-body for GLaDOS, all Test Subjects are maintained in stasis in these tanks.

Behind the scenes
The Stasis Chamber is first seen in the outro video of Portal 2’s co-op mode, when ATLAS and P-body discover the Vault. It is seen again in the following credits, when GLaDOS chooses her future Test Subjects from a screen on which the names of the Portal 2 team members act as the Test Subject's names.
