    I had a similar problem with peforated flasks. Turns out the weld on
    them was kind of sloppy and woould let air in. They are too
    expensive to just throw out, so I filed the welds down. Seems to
    stick better now, although I dread mixing investment so I havent
    played with them yet.  I've been using solid flasks with 100% seal.
    Hard to switch gears when a process takes this long and possibly
    won't work..
