Sounds like you're targeting an ultra centrifuge, even then I don't think out school's 'fuge is that tough. In addition, some 'blood' centrifuges for 100mL tubes are pretty much a painted steel bowl, just larger than you might have for mixing a very large salad for 10-15 people.

If they go faster than a 'blood' 'fuge then they have a bit more housing, but still little enough that a normal person could carry the device from one room to another.

The only 'fuges I've seen so heavy you can't move them are ultra and refrigerated centrifuges.



      Going for a powerful centrifuge seems like a bit of risk and lot of problems . So i think better make a smaller centrifuge for 1.5ml eppendorf with my 12v little 20 k motor and a 3D printed tube holder ,That won't be a bigger risk and i can analyse what errors will came on designing a bigger centrifuge .... Kind of a learning process

I think making the smaller model ill be the best thing before the bigger party :)
