1. A container for performing routine urinalysis tests comprising:

  • a large main longitudinal chamber for a urine specimen, said chamber circumscribed by a curved wall segment and a flat wall segment, said curved wall segment and said flat wall segment curved inwardly near an end of the chamber to form a narrow open throat extending into a end cul-de-sac-like chamber;

    a pair of longitudinal extending smaller chambers adjacent each other, said chambers circumscribed by a curved wall segment, and said flat wall segment and a partition wall segment between said pair of longitudinal extending smaller chambers having vertically extending spaced apart apertures therein, said curved wall segment curved inwardly near an end thereof toward and joining said flat wall segment near an end thereof to form curved bottom ends for said smaller chambers, one of said smaller chambers being calibrated to the equivalence of the routinely accepted specific gravity hydrometer and including a flotation component therein for determining the specific gravity of a urine specimen contained in said smaller chamber, the other smaller chamber containing a chemical reagent strip to test the quali-quantitative chemical constituents of said urine;

    said flat wall being non-porous to prevent the intermingling of urine in said main chamber and said pair of smaller chambers, said urine in said smaller chambers intermingled by passing through said vertically extending apertures in said partition wall;

    said end cul-de-sac-like chamber intergral with said main chamber and having parallel flat walls, curved side walls, and a curved end wall to define a narrow flat chamber to accommodate urine sediments said end cul-de-sac-like chamber having spaced horizontal and vertical lines to aid in the microscopic analysis of a urine specimen;

    a supporting and protecting rubber sheath surrounding the end cul-de-sac-like chamber;

    indicator means on the inwardly curved portions of said curved wall segment of said flat wall segment near said open throat for indicating the proper level of supernatant fluid to be retained in said main chamber for mixing with sediments in said end cul-de-sac-like chamber; and

    a transparent cap for said container, said cap having a chamber therein for storing a powdered stain and means for dispensing said powdered stain into said main chamber and said means comprising a rotatable portion having a top wall, a side wall, and downwardly slanting bottom walls terminating in an off-set aperture, and a stationary portion having an offset aperture therein and having an indented side wall mateing with a plurality of protrusions near an end of said large longitudinal chamber whereby said stationary portion is locked to said main chamber whereby the contents of said chamber in said cap may be dispensed into said larger chamber by rotating the rotary portion of said cap to align said offset apertures with each other whereby the contents of said chamber of said cap will gravitate into said main chamber.
