Abstract: At least one system for storage of pharmaceutical compositions includes: a container including a neck and a crown that includes an upper crown surface; a stopper including a flange and a plug, the flange including a lower flange surface and a flange height; and a holding element configured to exert a force on the crown and the flange to form a horizontal contact area between the upper crown surface and the lower flange surface. The horizontal contact area has a size of 30 mm2 to 300 mm2 and the flange height is compressed at least partially in the horizontal contact area by 10% to 40%.

Abstract: The present invention relates generally to an apparatus and kit in the microtiter plate format for improved multiplexed microarraying. The apparatus overcomes current limitations with conventional polymeric and glass bottom microtiter plates. The invention also relates to an apparatus for conducting multiple biomolecular assays comprising a low self-fluorescent coated substrate having an upper and lower surface. The substrate upper surface has a pattern comprising a plurality of wells. A flexible superstructure having a plurality of through holes (i.e. openings) in a pattern that is similar to and aligns with the wells on the substrate is removably adherable to the upper surface of the substrate. Preferably, the superstructure is adhesively attachable to the substrate. A tray supports the substrate and the superstructure and acts as an alignment jig.
