Hi 

I would be interested to know whether the filled epon centerpieces for the 
analytical ultracentrifuge, currently recommended for speeds up to 42000 rpm, 
can be used satisfactorily at speeds of 60000 rpm .

I recall a conversation with Preston Hensley on the topic.  Are there any 
additional measures which need to be taken?  eg tightening the cell a bit 
more, discarding the centerpiece after each run  etc.

Any advice or comments would be appreciated.
