This centrifuge head with axle (diameter ~2.8mm) is 3D printed in Shapeways’ strong bronze-infused stainless steel, and can hold four standard 1.5 ml Eppendorf microcentrifuge tubes. The axle can be held by a chuck or connected to a suitable motor using a shaft coupling.
For this centrifuge head you can convert RPM to G as follows:
(1.000 RPM = 60 G)
(2.500 RPM = 350 G)
(3.000 RPM = 500 G | spin down whole cells, cell nuclei)
(5.000 RPM = 1400 G)
(10.000 RPM = 5600 G)
(15.000 RPM = 12.600 G | spin down mitochondria, lysosomes, peroxysomes)
(20.000 RPM = 22.400 G)
(25.000 RPM = 35.000 G)
(30.000 RPM = 50.400 G)
(33.000 RPM = 61.000 G | ultracentrifuge level).
Please note that while we have tested the centrifuge head at 33.000 RPM, which is the highest setting on a Dremel 300 rotary tool, it is sold as a decorative object, as we cannot suggest that you use it for centrifugation for safety reasons. Using it for any other purpose than decoration undertaken entirely at the risk of the user, and we accept no responsibility for any negative consequences resulting from the use of this item.
