Analogue Black Holes: Disposal?

TL;DR

How are experimental apparatus and materials involved with analogue black holes disassembled and discarded?

Hi there, I'm a high school teacher and had a student stump me with a rather practical question. It concerns the analogue black holes I had read about in one of our universities, similar to this.

The student was simply curious how these materials are discarded after the data is recorded.

I had never thought about it, nor do I have the lab experience to know. I was hoping someone here might have some insights. The student realizes these analogues are not really like a real black hole, and are more of a model. Thanks.

Um, perhaps I should not reply since I have no idea what you are talking about, but I have no idea what you are talking about. Could you please post more information about this, and maybe a few pictures of how your student is using a mop to clean up a black hole in your lab? Thanks.

It is just helium and light. The light just gets absorbed and the helium evaporates after you turn off the refrigeration.
