A multi-well synthesis and filtration apparatus (10) dimensionally arrayed in a standard multi-well format for performing multiple chemical reactions includes a deep-well synthesis block (12) with flowthrough wells (24) fitted with filter disks (48), an upper cover (14), and a lower cover (16). First and second sheet gaskets (18 and 20) seal inlet portions (38) and outlet spouts (40) of the wells (24). An optional skirt (26) provides a site for the independently releasable attachment of the upper and lower covers (14 and 16) to the block (12) while maintaining the seal on the unreleased cover. An alternative synthesis apparatus (310) additionally includes a reinforcement assembly (372) to improve the clamping action of the covers (14 and 16) upon the synthesis block (12). A rotating carrier apparatus (200) and a modified oven assembly (202) are provided to enable agitation and heating of multiple synthesis blocks (12) simultaneously. |
