Hi Devin,

I use the Techne spinner flask system; the flasks have a steel ball inside a
glass rod which is suspended from the inside of the largest port lid.  The
flasks are robust enough to withstand repeated autoclaving, and I don't have
too many complaints, except about the price - a 1 litre flask is in the
region of £400!  I think these flasks are really designed to work with
Techne's stirring platforms though, so I don't know if they work as well on
other stirrers.
I read a post a few months back recommending Nalgene's polycarbonate vessels
as well - these are also reusable and the person using them was very pleased
with their performance.
