Stasis pods are devices used to hold a being in stasis. They are used by many races, which vary from by each race.
Stasis pod by culture
- Main article: Ancient stasis pod
The Ancients have Stasis pods which do not cause comete stasis, but rather slow down the metabolic rate of the individual in the pod. They will still age, but at a significantly slower rate (around 1 year for every 200 years in stasis.) Dr. Elizabeth Weir went into stasis to preserve Atlantis by rotating the Zero Point Modules every 3,300 years. Aurora-class battleships contain such Stasis pods. Colonel Jack O'Neill was placed in a similar Stasis pod in the Antarctic outpost to prevent his brain from being overwhelmed by the knowledge of the Ancients. This one looks to be much more sophisticated as when activated incases the subject in a block of ice and seems to nearly freeze all aging. Khalek was also contained within a Stasis pod between his times in the DNA resequencer. The Ancient ship Destiny contained a large number of Stasis pods, their performance compared to the newer versions of the Ancient Stasis pods is not known, but they appear to operate in a similar way. There proved to be just enough pods for the entire crew to enter stasis for three years, but apparently there were none left over as when there were problems with several of the pods, there weren't others that could simply be used.
Despite the aging process inside some Ancient Stasis pods - the Ancient Ayiana was found after millions of years in Antarctica with no signs of aging whatsoever. Whether a different, more long-term Stasis pod was used or whether Ancients simply possess the ability to "Hibernate" naturally is unknown. The former is more likely, however, as there would be no need otherwise for Stasis pods such as those on Atlantis and Destiny.

- Main article: Asgard stasis pod
The Asgard have also developed two types of Stasis pods: one to hold a being of their size, and another to hold a being of human size. Asgard size stasis pods are capable of sustaining an Asgard in perfect hibernation, probably with around the same level of aging as Ancient ones (although each Asgard clone has a shorter life expectancy than a human). The pod is capable of surviving in the vacuum of space. They are also equipped with subspace location devices to allow them to be found and rescued by nearby ships.

- Main article: Stasis jar
In addition to a jar specifically designed to preserve a symbiote, the Goa'uld have developed pods which are capable of holding a person in stasis, cryogenically freezing them. If a host who is still undergoing the implantation process is frozen, the symbiote will be unable to take control of the host and will die. Additionally, the Sarcophagus is capable of keeping one alive almost indefinitely, however the sarcophagus is based on Ancient technology. (SG1: "Hathor", "Out of Mind", "Into the Fire", "The Curse")

- Main article: Hebridian stasis pod
The Serrakin introduced stasis technology to the Hebridian people after they liberated them from the Goa'uld. They use stasis technology aboard several of their vessels most notable the Sebrus type ship, designed to transport criminals in stasis to a prison world, this relinquishes the need for a brig. (SG1: "Forsaken")
- Main article: Talthun stasis pod
The Talthuns developed stasis technology, when their star destroyed Talthus. As their ships were incapable of faster than light travel, they developed a form of stasis that perfectly preserved the body, but also removed the consciousness from the body. If the body should die, the consciousness could be downloaded into another body. (SG1: "Lifeboat")

- Main article: Ursini hibernation pod
The Ursini also posess stasis pods that can keep their occupants' brains active during extended hibernation periods. The pods also provide basic nutrients to the user. The pods are also compatible with humans. (SGU: "Awakening", "Resurgence")
- Main article: Virtual reality pod
The Keeper was able to develop stasis technology and a virtual reality pod that kept his people safe and active while P7J-989 became safe to inhabit. There are certain doors with special markers that allow one inside the virtual reality to leave. However, even after the planet was healed, he didn't tell them it was safe, for fear they would destroy their world again. The charade was finally ended when SG-1 was forcibly taken, and exposed the Keeper's lies. It is supposed that the chairs do not age the inhabitant in the same way as the Ancient and Asgard counterparts do. (SG1: "The Gamekeeper")
- Main article: Hibernation pod
The Wraith spend roughly two centuries in stasis between cullings, during which the humans of Pegasus will repopulate their galaxy. Whether the stasis is solely to allow human population growth or is a biological need is unknown. While in stasis, they cannot be detected by a life signs detector. Because of the vulnerability the Wraith place themselves in by sleeping, a small group, lead by a Keeper, will guard them. If the Keeper should die, the rest of the Hive ship will awaken. While inside the hibernation pod, there is a constant flow of fluids between the Wraith occupant and the Hive ship. The Wraith also use stasis technology to keep humans alive to be fed upon in the future, by cocooning them. (SGA: "Rising", "The Defiant One", "The Gift", "Infection")
While it is unlikely that stasis technology can completely stop a person's aging process, one might be able to augment the effects of a stasis pod by adding a Time Dilation device to the setup, slowing time around the stasis pod itself by a configurable factor.
For instance, if a time dilation device had been installed aboard the Aurora and set to move time at half its normal rate, the Ancients in stasis would only have aged half as much in the same 10,000 year period as they did in the show.
An irony of this approach, however, is that while a person's aging will be reduced, their thought processes will also be affected by the temporal lag. And while this isn't a concern for stasis pods that lack a neural interface, if a person wanted to control the time dilation device and the stasis pod from inside one that does, it would take longer for any mental input to be translated into action.
