Abstract
Devices and methods for packing a chromatography column with a continuous stationary phase. The preferred device includes a brace member with an engagement surface. The brace member defines a thru-hole at a location so that a passageway defined through the column is aligned with the thru-hole of the brace member when a first end of the column is engaged with the engagement surface of the brace member. A funnel member engageable with an end of the column opposite the first end. The funnel member has converging walls configured to radially compress the continuous stationary phase for entry into the passageway of the column when the continuous stationary phase is pulled through the funnel member. The device includes a mechanism for applying mechanical force to pull the rolled continuous stationary phase through the funnel member wherein the stationary phase is radially compressed and enters the passageway of the column.
