simple centrifuge for 2ml containers

Summary It's just a simple centrifuge head to attach to a DC motor (powered with 9V). I did simple tests and it works fairly well. Warning: do touch with your fingers or put in contact with objects while it's working, it hurt, and it can damage fragile and shredable materials. Also don't forget to put both tube and add rougthly the same amount of liquid in both, to equilibrate. P.S: this also works as a fan, with airflow from the top to the sides.
