Labconco Lyph Flask Top 500 750+1000ML. It is often used with blood bank tubes or other large volume vessels where volume expansion and/or contraction is desired. The draw down feature of this fallout lyophilizer is excellent for reducing volume without changing the freeze-thaw cycle. Just draw down on the release bulb to expand the volume by the amount desired. When the level gets too low the lyophilizer can be removed and the flask recapped and returned to the freezer for reuse.
