A multi-compartment housing with a plurality of cavities forms the main part of the housing. The multi-compartment housing has a side portion that has a smooth, continuous surface and a plurality of individual cavities that are perpendicular to a central axis of the multi-compartment housing. The individual cavities have a plurality of plugs capable of being placed in communication with a corresponding individual cavity. The multi-compartment housing also has a sealing bottom that is capable of being secured onto the multi-compartment housing after the plug array has been placed in position and separated from adjacent plugs from the array so as to close off the of the multi-compartment housing and to isolate each plug from adjacent cavities.
