Proper research analysis requires a fully stocked and organized study storage area. The room should be safe and free of any hazardous substances, and it should be set up for the convenience of researchers. Laboratories for studying include areas for storing supplies, vials of test substances, test tubes, tissue culture tubes, cell culture plates, sensitive medical instruments, immunoassays, and gas chromatography. Also, a laboratory provides access to the laboratory for the staff and maintenance staff.
For medical research, labs can range from simple laboratories with minimal input into sample preparation to those designed to handle large volumes of sample preparation. For example, in the dairy industry, one may have three laboratories for a single dairy, with sample preparation and analysis in different rooms. Similarly, in a clinical setting, a single laboratory will perform most clinical analysis, although some sample preparation is performed in an exam room or other room. The concept of a clinical laboratory is to separate health care from research.
