More Information:

Cathal Garvey, 3/21/10: After a design revision which is now “official” and for sale on Shapeways, the Dremelfuge can hold tubes securely, with liquid load, up to the full speed of a Dremel 300. At a top speed of 33,000 RPM, this means the tubes experience about 52,000RCF (g).

For scale, my lab centrifuge used daily does up to 14,000g and I’ve never practically needed higher. I gather high gees are used to perform sucrose gradients, and I’m told that 52,000g is enough to pellet DNA. I’ll be sure to experiment.
