>Does anyone know of any new concentrators on the Market for starting volumes
of 10-15mL? The device I use now requires me to continually stop my
centrifuge to decant..thats a drag.
>Millipore has a new one which concentrates downwards. The down side is that
you gum up the membrane more easily (if that's a concern). It does work as
least as well as the Amicon IMO.
