Re: [DIYbio] DIYBIO what type of centrifuge should I buy?

Use a brushless DC motor and an ESC.

They are relatively cheap from hobby stores online, and they are of surprisingly high quality for the money.

If the ESC accepts servo-like signals, it can be easily controlled using, say, an Arduino .. then you have a reasonably simple way to implement arbitrarily complex speed/time sequences.

Here's one example of a centrifuge created using this basic approach.
