centrifuge

A centrifuge is a must in every molecular lab. It is used for speeding up diffusion processes. Basically a high RPM carousel for bio samples that will separate solids and liquids into distinct layers, which you can later separate using micro-pippetes layer by layer.

caveats & challenges:

1. set RPM so that plastic (3D printed part does not explode by high centrifugal forces)
2. learn how to use powerfull brushless motors and arm them using microcontroller and an ESC to drive power to it
