96 well plate / 0.2 mL strip tube Magnet Rack
by acadey, published
NOTE: The first prototypes pull beads ~25-30% slower than commercial versions - also they require more care when removing the super. This I believe is due to the depth of the magnets and I am working up a new model that uses different sized magnets that may work better.
Also if you are a grad student and are trying to convince your PI to buy a 3D printer - making just two of these will pay for the printer. These things are ridiculously overpriced.
UPDATE: Added a version for smaller square magnets. Will add more details soon, but hopefully this will allow the beads to be pulled higher on the tube. Also the magnets are a pain to glue in place - I am going to try a much faster drying glue and hopefully that will work...

Added a new version for smaller, square magnets that may help pull beads higher up on the tube wall. Still in development, so any feedback is appreciated. I will hopefully have some results soon, but it is jammed into the middle of a long to-do list...
There actually is no top part. It is designed to hold entire 96-well plates. If you want the top part with the holes, the best way is to take a skirted 96-well plate (where there is a hard shell and the tubes are of different, clear plastic - I have a link to an image below) and just cut the tubes out by running a razor over the top (carefully - its easy to cut yourself since the blade can get stuck).
