Science in Progress: D-I-Y Home Centrifuge

Centrifuges are typically found in the lab, but with this 3D printed design, we can tap into its awesome power in the home! Kishore and Indre bring in our 3D printing expert to help make this kit work, and put some centripetal force on some fruit.

  1. THAT is pretty impressive.

    Now I just have to convince my lab that they have to buy me a 3D printer to print a bunch of these and make substantial economies 🙂

    I would love to see where you got these files. also, Kishore mentionnend a magnetic stirrer which would be awesome to see

    thanks for this vid guys

    BTW, just to troll a bit, this is not amplified DNA, just extracted or purified… or did you manage to print a thermocycler off camera? because that would interrest me for sure given the price of such equipment [troll – OUT]

  2. shoot, did I say amplified? That’s a mistake. You’re not getting me to build a PCR next to fix that mistake either.

  3. shoot, did I say amplified? That’s a mistake. You’re not getting me to build a PCR next to fix that mistake either.

    damned, I was kind of hoping though… I guess I’ll have to make my own then! 😉

    Anyway it warms my heart to see Tested speaking about lab stuff. Can’t wait for more.

  4.   why not building a pcr machine to amplify DNA fragments? It is just a 3 step thermocycler. Problem is to get the Taq polymerase and the 5 and 3 end primers specific for particular gene of interest. But I bet you can get those ordered in China somewhere cheap.

  5. I love the look of absolute glee on Kishore’s face when they turn it on for the first time with actual stuff in there 😀

  6. So, about those DNA strands.. I wonder if you could use this handy little guy with amateur scientific research or education… how do they look under a low cost 40x – 1000x microscope?

  7. my lab burns through centrifuge’s so fast. They are so expensive. However, the 3d print one would not be substantial enough for our needs.

  8. Not sure if it would be any benefit but you could have the drone motor facing down with two different size wheels and a rubber band or rubber belt between the motor and the centrifuge spindle to offset the speed a bit and to maybe absorb some of the shakiness. If you could take readings of the RPMs at max speed, you could offset the wheel sizes and make them replaceable to have more accurate speeds for whatever the needs may be..
