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 […]
PuffAdder: A DIY Picospritzer
No not the snake. This is the name Joe Raimondo’s DIY picospritzer, which delivers picoliter to nanoliter “spritzes” of liquid in short pulses. His blog gives a great step-by-step guide to building one. And if you’re looking for something a little more robust, check out their paper on Openspritzer in Nature where they build and […]
Technical Tuesday: Protein Purification on a Budget
Welcome to the first Technical Tuesday! Where we try to dive a little deeper into the actual costs involved in particular scientific techniques. We hope to show where you can save money, and what you might lose by saving that money. Today’s topic is protein purification by columns thanks to Dr. Marc Ridilla who provided […]
Tiny Florescence Microscopy
Check out this 3D printable florescence microscope with filter wheel, digital acquisition, and temperature control! All for less than half a grand. Dr. Peter Foster recently made one of these himself so we have at least one solid positive user experience with the device. However Peter says he took a shortcut with the illumination LED […]
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 […]
