With very simple items I had laying around I was able to build this sample rotator. It rotates very slowly. This will allow samples to be mixed. I hope to place it in my incubator to attempt to use as a shaker for the media broth for cultures (continual mixing).

Parts: the motor came from an old hand-held vacuum, I bolted a disk from the bottom of a cd holder on to it. The frame is from an old computer power supply box (the top half). I use 1 inch PVC conduit clamps to hold the motor in place. I use broom handle wall clips to hold my culture tubes. They had to be adjusted to fit both 15 ml and 50 ml tubes. They are mounted on the plastic disk with nuts and bolts. It runs using a power supply that ranges from 1.5v - 12 v.
