Open Source Laboratory Sample Rotator Mixer and Shaker

thingiverse

This laboratory sample rotator is engineered for both gentle mixing and vigorous tumbling in tubes of various sizes by rotating them horizontally, vertically, or anywhere in between. Quickly switching the rotation angle requires no tools at all. Equipped with a built-in Arduino-based microcontroller, this device adds the functionality of a high-performance laboratory sample shaker. Users can modify these open-source devices both mechanically and functionally by selecting operation modes on a switch or altering code to perform custom experiments. The open-source laboratory sample rotator mixer can be constructed by non-experts for under $30, while adding shaking functionality costs just $20 more. Therefore, these cutting-edge open-source devices outperform expensive proprietary commercial equipment available in the market while saving over 90% of the costs.
