Magnetic Rack for 2, 4, and 8 1.5mL tubes

thingiverse

I needed a magnetic rack that would hold magnetic resin securely in place. These are racks designed to accommodate two, four, and eight 1.5 ml tubes. They require two to four 10x10x5mm magnets per hole. Using only two magnets per hole may cause the magnetic resin to shift while removing the supernatant. In my case, three magnets proved sufficient. To prevent the magnets from protruding from the rack, you can wrap it with clear cellophane tape, also known as sticky tape.
