BoSL Bead Beater

This section shows the BoSL bead beater The BoSL bead beater is a low-cost, open-source, freely available 3d printed bead beater for DNA and RNA extraction. The device can fit with any commercially available portable jigsaw, the 3D-printed components can extract six samples at a time and the bead beating function is achieved by driving the sample through the rapid movement of the jigsaw blade.

Design Journey

Design 1 At the start, our initial design key points are

1. Using a screw base and top to hold the extraction sample.
2. Connection parts to connect the jigsaw blade and screw base.

Firstly, we made a circular screw base and top with a 64mm diameter and 6 sample placement holes. Meanwhile, a two-piece cylindrical clamp component clutched the jigsaw blade with studs and M4 screws. Then that cylindrical component is connected to the screw base by using two M4 screws.
