Will it centrifuge? Answered

Picture of

I have recently obtained a desk-top centrifuge which has yet to be used. It takes tubes with a volume of 1.5ml, and subjects them to accelerations of up to 8500 gravities (by comparison, most theme park rides top out at 5 gravities).

So - what should I put in it?

I plan to collect ideas and then spend an evening or a weekend in the shed...

Edit:
First results are in.

You sure it was doing 13k rpm? Your PSU @ 12v gave 1A = 12w lol
Wire that beast up to a high wattage ATX PSU or a car battery...then it'll spin :)

You could always go for broke and 24v it :):)

If you check the links, one of the slides shows the centrifuge's specifications, including rpm vs voltage. There is very little weight in the rotor, and the bearings are very smooth.

Thank you for this great instructable. In my years of acquiring the odd and bizarre, I do happen to have a centrifuge. Other than blood, I couldn't think of anything else to do with it. Thanks for the ideas and please, other readers, contribute more ideas on uses for a centrifuge.

I reccommend gasoline and, if y'all have it over there in the UK, E85. Spit. I'd like to see spit centrifuged. And I have a question (I know, I'm impossible this time of the morning): what sort of RPM does that centrifuge achieve?

what's up with you guys?
I am still waiting for an instable. somebody please make a centrifuge.
I have three other projects going so I don't have the time to experiment. I also got 30 Lithium Ion battery packs. what to do, what to do. maybe the folding electric bicycle?

I was working on one, but was struck by a bolt of common sense. Spinning a home-machined steel drum about at 20,000 rpm seemed like it might do a little damage... to my favorite router, not myself. Anyone have any tips for machining with precision when one's only machine tools are thridhand at best and homemade in the middle of the night at worst?

. I think I'd try separating a petroleum product. See how many different components you can separate from, for instance, 3-In-One oil. Or anything else made of liquids with slightly different weights.
. Blood or other body fluids.

Do we know if the "sediment" in the lamb's blood was some of the red blood cells or maybe some micro-clotting because if the age of the blood, or maybe some other contaminate?

Apparently I over-spun the blood, and the cells broke up - maybe it was the "shells" (membranes) of the red blood cells?

lol. In science my teacher told me that one TSP of the matter of a neutron star would weigh over 1,000,000,000 tons( It might have been 1,000,000 but anyway its a lot) What about a black hole? How much gravity does that have anyway? I know it has enough to kill me but exactly how much is that? lol, you should try putting a swab of your cheek cells in there, who know what would happen. And Jello, as Jello can change it shape and then form back, i just wonder if it would make it something like liquid.

What?

I'm not against killing vermin, I am against killing them in a potentially slow and needlessly painful way. Yes, I know they're "only" insects, but I try and have respect for all living things, as an example to my children and my students. It is but a few short steps from "it's only a fly" to "it's only a dog" and then "it's only a >insert minority group<".

In fact, atheist though I am, I rather like the old druid credo; Do what thou wilt, an it harm none.

It would depend on "how" the centrifuge works. If ONE container is just spun rapidly, the flour should evenly spread out over the inner surface, but if it is like the centrifuge the uses little bottles, it would compress a bit into the bottom of each bottle, yes, I would think anyway.
