For nearly every other science fiction trope there is a name. A movie where the heroes travel faster than light, whether they actually name the mechanism or not, will be called subspace/warp/hyperspace. Even the bolts in Frankenstein's neck have a name...

But the device I am referring to, surely there is something that this is called and I am merely ignorant of what that is, so what is it?

For those who want a precise definition: it is roughly 7-9ft tall. 30in to 48in in diameter. Cylindrical in shape. The front or even the entire exterior will be glass or a strong see-through substance. Usually they are upright, though occasionally they'll be horizontal. It will have a translucent (often colorless) liquid in it. Bubbles are often seen floating to the top, though not required. Sometimes the person placed in it has a facemask for breathing, this isn't required either. The purpose can range from maturing a clone, to healing the injured, or even at times placing them into some sort of suspended animation (bonus: you come out of stasis with perfectly conditioned hair and soft skin!).

    I am going to start referring to them as "cliche science fiction glass tube filled with liquid and a person floating in it" – NimChimpsky Oct 13 '12 at 6:33

    “Even the bolts in Frankenstein's neck have a name” — they do? – Paul D. Waite Dec 1 '15 at 20:30
  • Starship Troopers, in case you need another example :) – Kevin Laity Sep 13 '18 at 21:05

You might be looking for what TvTropes calls People Jars.

Examples they give include the Bacta tanks from Star Wars, the device Leloo was reconstructed in from 'The Fifth Element', and quite a few others.

They capitalize on the creepy factor of humans in jars, that (for a long time) people associated with biological experiments and medical oddities. (Think of the Mermaid Baby fetus exhibits at carnivals, or the jars containing brains of famous scientists.)

They are creepy enough just as they are... but add the possibility that they are alive (sometimes shown in horror movies with eyes opening) and they become VERY creepy.

    @wopr - Yep; follow one of those links, and your productivity for the day is gone.... :) – K-H-W Dec 20 '12 at 14:39

A jar of that size can be safely called a "vat". I find it more fitting than jar. But I can't think of a general term for vats used for storing humans (or other living creatures).

    As the TVTropes page says, "Oh, call them pods, tanks, containment units or chambers all you like. These are people in jars." (Also, as a devoted fan of Lois McMaster Bujold, the word "vat" to me calls up "vat protein", so using this term for something that holds people achieves the impossible: it makes it even more disturbing.) – Martha Oct 13 '12 at 1:09
  • Agree with vats. Cloning vats, biovats, rejuvenation vats.. – Junuxx Oct 13 '12 at 11:35

I was thinking "artifical womb" would be a good name, and the TV Trope I got back from a search for that was Uterine Replicator.

Wikipedia has a list of many of the Artificial Uteri in fiction. (Mostly Sci-Fi, of course.)


"Stasis" is mentioned in the question as a common purpose of these cylinders. Terms based on this, such as "stasis chamber", "stasis pod", etc. should cause little confusion. "Stasis chamber" appears to be the most common variation, occurring in hundreds of books.


The modern equivalent to this is a Sensory Deprivation Tank or Isolation Tank. The "real life" / scientific use of a tank like this is to experience a altered state of consciousness which is purely mental compared to the depiction in science-fiction as a way to cure physical ailments. Below is a screenshot from the movie Altered States (1980).
