Eppi Vortexer AND Rotor Adapter

https://vimeo.com/135430249

Not only do I need to vortex many eppi tubes, I need to gently agitate them for ~20 minutes. To facilitate this second step, I built a little rotator that the vortexer assembly slides into.

I repurposed a burnt up servo from other projects to provide the rotation. This is still a work in progress.
