Dremelfuge – Surprisingly Powerful Small Centrifuges from Power Tools

You can 3D print or Buy adapters for Dremel power tools to centrifuge 1.5 ml eppendorf tubes. This isn’t a little replacement to those mini pop-top centrifuges that ponder around at 10,000 rpm and only give around 5,000 g, oh no. Dremelfuges can hit 33,000 RPM and upwards of 51,000 g.

If 3D printing is your jam, you can modify the design to hold the types of tubes you need, or alter the features to, for instance, add a swinging bucket as shown in this video.

For just around $100, you can grab something like a Dremel-300, which can also be used for fabrication.

Precise Parafilm Designs

While more expensive than a razor blade, you can cut Parafilm or tape to make precise chambers and masks without a laser cutter by using a commercial knife printer like the Silhouette CAMEO.

From our own experience its remarkably robust though it can be a little finicky when loading the cutting mat before that actual cutting begins. The product comes with Silhouette Studio, a2D CAD software that’s easy to design with and allows you to import designs from other standard formats for “printing”.


UV Lamps

Need a UV lamp for curing purposes? Consider buying a commercial product for curing nail polish. Amazon has a whole category just for UV Nail Dryers !

Some cardboard and tinfoil does a good job of isolating UV rays, and a nice hinge can be made with Velcro.
