# Magnetic Separator Rack Design files for custom, 3D-printed magnetic separation rack for bead-based separation of biomolecules. ## About These racks are designed to support two sides of 6 1.5-2.0mL microcentrifuge tubes. They use long, rectangular magnets set lower on the tubes than most commercially available racks allowing for good separation even with very low volume samples. In addition, racks are designed to slot together to allow for expansion when more than 12 samples need to be processed. Two designs are available. The _Two Part_ design features a removable top so that samples can be vortexed at the same time without removing each tube from the rack. The _One Part_ design is a single part where the top and bottom are connected. ### Magnets These racks are designed to accept a 5/8" x 1/4" x 0.1" neodymium magnet. We use ones available from [McMaster-Carr](https://www.mcmaster.com/5848K78/). ### 3D-Printing These racks have been designed for printing on an SLA 3D-printer. We use the Formlabs Form3B with Color V1 resin. Your mileage may vary with different 3D printing technologies. ### CAD Files for Modification In addition to the STL files, CAD models can be found at OnShape using the links below: - [One Part](https://cad.onshape.com/documents/ac3f1812ea71904c4083b250/w/dbaaac48466942043f92d1b7/e/5bb39ef93866d42250d2d921) - [Two Part](https://cad.onshape.com/documents/ac3f1812ea71904c4083b250/w/1948a836c2f0dd5088106535/e/5bb39ef93866d42250d2d921)
