Abstract
A column unit is provided consisting of a centrifuging vessel and a receiving body with feed and discharge openings located at opposite ends. Desired column material is located within a middle portion of a hollow cylinder of the receiving body. A portion of the receiving body containing the discharge opening and the column material is received by the centrifuging vessel. The entire column unit is inserted into a conventional stand in a centrifuge. Accordingly, when sample material is introduced into the receiving body through the feed opening, it may flow without misdirection through the column material and discharge opening and into the centrifuge vessel.
Claims25
A column unit for insertion in a centrifuge to separate or react a sample material, comprising:
- a first vessel including a feed opening at a first end of said first vessel, a discharge opening at a second end of said first vessel, a hollow cylinder between said first and second ends and column material located within a middle portion of said hollow cylinder, wherein a sample material may flow through said feed opening, said column material, and said discharge opening;
- a second vessel configured to fittingly receiving a portion of said first vessel comprising said discharge opening and said middle portion of said hollow cylinder, wherein the sample material may flow through said discharge opening into said second vessel;
- a feed cap which seals said feed opening of said first vessel;
- and
- a means for attaching a syringe to said feed cap.
