Definitions

  • Such a die cut plate will have openings conforming to the shape and size of the desired filter means and the die cut plate will be placed in register with the openings of the wells or the upper openings of the second part.
  • a cutting stem may then penetrate the openings of the die cut plate thereby cutting the filter means out of the filter sheet.
  • the cutting stem may then also push the filter means in the openings of the wells or the upper openings of the second part.
  • the filter means When the filter means have been placed in the openings of the wells, the filter means will abut along their periphery the inner surface of the one or more side walls enclosing the interior of the wells.
  • the filter means When the filter means are placed in the upper openings of the second part, the filter means will preferably abut along their periphery the inner surface of the side walls enclosing the upper opening as well as the first end of the spouts. It is also possible to cut the filter means out of the filter sheet by means of other cutting techniques such as laser cutting and cutting by means of water jets or by providing sharp edges circumscribing the bottom opening of the wells of the first part or circumscribing the upper opening adapted for receiving filter means of the spouts of the second part.
  • other cutting techniques such as laser cutting and cutting by means of water jets or by providing sharp edges circumscribing the bottom opening of the wells of the first part or circumscribing the upper opening adapted for receiving filter means of the spouts of the second part.
  • the filter means having selectively adsorbing material has chromatographic properties, which can include ion exchange properties or affmity-chromatographic properties, if the filter means comprises suitable affinity ligands.
  • a preferred filter means comprises a fibrillated polytetrafluoroethylene matrix having enmeshed therein sorptive derivatized silica particulate as are disclosed in U.S. Pat. Nos. 4,810,381 and 4,699,717, respectively.
  • FIG. 6a-d there is illustrated a further embodiment of the present invention in which the first and second part are permanently and i ⁇ eversibly bonded together by mutually engaging mechanical means.
  • a first part As shown in Fig. 6a, there is provided a first part
