Designing a microscopy and/or analytical instrumentation facility can be completed in a step by step approach, whether it is a completely new facility or an existing one moving into expanded quarters. The procedure is independent of size. The same basic procedure is required for one room or an entire building. There are several major factors that must be taken into consideration. Check lists can be compiled by the microscopist/analyst. One should easily be able to start at any point along the way. The time and effort Initially put into the design will pay for itself many times over in both the convenience and efficiency of the resulting laboratory.
