Claim 16

The self-packaged structure of claim 1 wherein the fraction columns are adapted to receive a delivered reagent through an upper inlet opening and release a modified reagent through a lower outlet opening and means disposed within said fraction column effects flow of said delivered reagent therethrough and modifies same.

Claim 17

The self-packaged structure of claim 15 wherein said means disposed in said fraction column comprises a media support member in the form of a glass fiber-like button.

Claim 18

The self-packaged structure of claim 15 wherein said upper inlet and lower outlet of said fraction column includes removable closure means.

Claim 19

The self-packaged structure of claim 17 wherein said removable closure means includes upper and lower caps fractionally engaging with respective inlet and outlet openings.

Claim 21

The self-packaged structure of claim 15 wherein said fraction columns are disposed in the openings of at least one rack, collection tubes are disposed in the openings of another rack and in operation, the fraction column containing rack is disposed over the collection tube containing rack with outlets of each of the fraction columns disposed in an upper opening of a corresponding collection tube for collecting modified reagent from said fraction column.

Claim 22

The self-packaged structure of claim 20 wherein means is provided for identifying each collection tube and fraction column for orderly arrangement thereof.

Claim 23

A self-packaged structure for use as a test kit comprising collection tubes and fraction columns adapted to be supported in said structure in any array including: a plurality of racks each adapted for supporting fraction columns and collection tubes and tray means adapted for securing one rack adjacent to another in tandem to form a modular package; each of said racks comprising: a modular integral monolith including: dependent legs, and a horizontal support member joining upper portions of the legs, the support member having a plurality of through holes therein aligned adjacent one another between the legs, the holes adapted to receive the columns and tubes in substantially upright fashion, upstanding lugs disposed on an upper surface of the support member and aligned with a lower horizontal support surface of the legs, the legs having complimentary recesses therein shaped for frictionally receiving the lugs of another of said racks to facilitate stacking of one rack over another; said tray means including spaced pairs of lateral recesses arranged in tandem for receiving portions of the legs of the racks, and means located between at least one pair of the lateral recesses in selected spaced relation with the support surface of a rack received in the lateral recesses for allowing only a rack containing tubes therein to be located in said recesses; elongated stepped upper and lower bosses formed in the upper surface of the support member, the lower one of each boss being of a selected length and the upper one of each boss being of somewhat shorter length, said upper boss being lengthwise off center in the same direction relative to the lower boss and the respective complimentary recesses for each stepped boss being disposed in lower support surfaces of the legs in vertical and axial alignment with the lugs, each recess having a stepped mating profile such that, only one alignment of the lugs and recesses is correct for stacking the racks.
