ABSTRACT:
A disposable specific gravity tester of liquids such as urine comprising a form-maintaining, flexible or resilient, transparent plastic pipet-type tube, one end of which is integrally closed to form a self-contained bulb, the other normally open end of which is fixedly closed with a solid liquid-permeable plug permitting inward passage there through of the liquid to be tested, and at least one floatable solid testing body in the tube with a predetermined specific gravity at or approximating the expected or normal specific gravity of the liquid; and its method of use, comprising squeezing the bulb while the other plugged end is below the surface of the liquid, releasing the squeezing force to suck up into the tube sufficient liquid to float the testing body or bodies, and observing if and/or which body or bodies sink, float or remain suspended in the liquid.
