Abstract:
A test tube rack having columns and rows for manually performing medical diagnostic assays which require various sequential operations. The top face of the rack has indicia such as color strips and written directions to provide a program of operations which is to be followed in a particular assay. The individual test tubes are manually progressed in columns from row to row as the programmed sequence of operations is carried out. The top face may be replaced by other top plates programmed for other different assays.
