Description
A centrifuge is a rotating wheel with very high rotational speed (RPM) and a strong body protecting the people around from the energy of the fast moving parts. Substances are loaded into the vial holders at the edge of the fast spinning wheel and are separate along their different densities. Fast spinning computer hard drives in a solid aluminium housing are perfect for making small do it yourself centrifuges.How ToThe design is based on conventional 3.5? desktop hard drive. You usually need a small torx screw driver to open them. The disks are removed and replaced by a laser cut acrylic tube holder. Only small centrifuge tubes (0.5 ml) can be used with this kind of design. Make sure the tube holder fits well on the shaft of the motor and fix it back with the original down holder. The parts for the housing provides a stable stand and allow easy opening of the lid. To drive the motor replace the electronics by a ESC brushless motor driver for RC cars. To control the speed use a so call Servo Tester" unit that fits well with the motor driver."
