I have been using a commercial version of this method to prepare
fragments from low-melt agarose gels.  5 Prime->3 Prime, Inc., sells what
they call Phase Lock Gels which come pre-packed in tubes of various sizes
and in two different densities of the gel.  My experience has been good,
but not always.  Sometimes the gel does not form a tight plug, and it is
harder to separate the phases than if the gel were not present.  When
this happens there are wisps of the gel in the upper phase, and I cannot
pour out the upper phase.  However, 90-95% of the time it works fine.

Good luck,

Jim Owens
