Abstract

An array of stoppers held in a lid. The stoppers have indentations in their top sides that slide into tracks or recesses in the lid. The lid holds the stoppers so that they may be inserted into the wells of any multititer plate by either hand or machine. The lid has a removable end that allows for the sliding removal of the lid without removing the stoppers from wells that form the multititer plate or tray.
