microfuge swinging bucket rotor??

[David A. Adler]

Hello,
We are interested in doing differential centrifugation on a micro-scale.  
Does anyone know if there are swinging bucket rotors for a microfuge type  
centrifuge and has anyone tried this, for example: sucrose gradients.

I am posting for a friend, please send replies via email directly to:

thanks for any assistance,
David
