[DIYbio] Re: DIY Centrifuge

an Centrifuge with 25k rpm ah ha.. sounds interesting but can you elaborate more about the practical 

application of your centrifuge , there are several types of Centrifuge like Microcentrifuges, Ultracentrifuges 

and  High-speed centrifuges with an angular speed varying from 500 rpm to 70k rpm in theory but when coming to 

practical applications like Fractionation process and cell Separation processes we don't need such hi-speed angular speeds

in general what we do usually in labs is if the angular speed is less then we increase time of centrifuge.. 

but you boys always want to have a fastest machine hehe..

any way have a look into this link

its pretty simple centrifuge used from a bad HDD innovative idea but it defiantly needs an en-closer for safety purposes

and it runs at 6k to 12k which is pretty good ...

and i wish you all the best in your diybio venture to build a centrifuge @25krpm but do remember safety comes 

good luck

Hey Guys,
                     I am designing a Centrifuge for my collage. our centrifuges don't have the capacity to carry 100ml tubes in it it came as a big problem for us . So collage is willing to fund me for making a centrifuge and to put the data as open source. I need your suggestion for choosing the motors for it . Presently i am having 3564 B BLDC motors with 25k rpm(dont have that much torque) and a multirotor with 2.1kg thrust(which i used to make a quad copter) , I am not sure these two are not a good options for  centrifuge motors. All you guys are expert in these area , So please give your suggestions for that

ill post the designs when my term exam is over :)
