Elke:  The GSA is for a High Speed machine, not an ultracentrifuge.  It
won't spin a t 45 Krpm.  T

Keith:  There are bulk rotors that use sectional vanes rather than bottles
for high capacity ultracentrifugation.  Haven't ween one used in quite a
while but from what I remeber, you used to have to have a special loading
device fitted to your centrifuge.  Therefore, I think that the costs might
be prohibitive.  Try lots of smaller tubes?8-)
