Open Source Nutating Mixer

pinshape

Summary A revolutionary 3D printable desktop nutating mixer that offers a fixed 20° platform tilt angle for gentle three-dimensional agitation of chemical or biological samples, such as DNA or blood samples, without foam formation is available. The custom components for the nutating mixer are designed using open source FreeCAD software to facilitate customization. All non-readily available components can be fabricated with a low-cost RepRap 3-D printer using an open source software tool chain from common thermoplastics. The designs are open sourced and can be configured to add more functionality to the equipment in the future. Assembling the mixer is relatively easy, making it accessible to both younger students and state-of-the-art research laboratories. The open source nutating mixer can be fabricated with US$37 in parts, which is 1/10th of the cost of proprietary nutating mixers with similar capabilities. The open source nature of the device allows it to be easily repaired or upgraded with digital files, as well as to accommodate custom sample sizes and mixing velocities with minimal additional costs.
