摘要

A solid phase extraction plate (10) includes a unitary tray (12) having a plurality of spaced-apart discrete upstanding chambers (14) molded therein with each chamber (14) having a top opening (16) and a bottom nozzle (18) with downwardly tapering sidewalls (24) extending between the top opening (16) and the bottom nozzle (18). A plurality of solid phase extraction disks (28) are provided and one secured in each of the plurality of chambers (14) without the use of frits or retainer rings utilizing instead tapered sidewalls (24) of the chamber (14) for enabling a press fit of the disks (28) therein.
