A configurable device interface enhances the ability of a processor to communicate with other devices. The stored data set can represent at least one previous measurement collected during a previous instrument validation process performed on the analytical system. Each segment has a concavity positioned between inwardly projecting arcuate surfaces that engage grooves in the pipe elements. The system and method described herein is designed to reduce bias due to the human nature of the tester, while still maintaining versatility, individualized attention and depth of analysis in testing. The subframe generation logic is configured to generate a plurality of subframes for each of the at least one derived color subfields. These improvements are due, at least in part, by providing an aquarium having a recess portion extending inwardly from a wall portion, wherein the recess portion has a transparent or translucent surface for transmitting external light into the container and optionally a shelf structure for supporting aquatic items placed in the aquarium.
