ABSTRACT:
This invention relates to a device and a method for measuring the specific gravity of liquids, in particular, urine. This invention more particularly concerns a component of an automated system for urinalysis, either of humans or animals. The device may also be developed as a stand-alone unit and includes a dispenser, a sample container in which the liquid is dispensed and flushed, and a fiber optic sensor system to record the refractive index of the liquid. The invention is particularly suited for use with small clinical samples.
