ABSTRACT:
To examine urine for particulate constituents, the urine is pased through a filter of synthetic fibers that are soluble in alcohol or in an alcohol-water mixture immediately after withdrawal. The filter material together with the constituents retained in it is then immediately dissolved in a cell-fixing solvent, in which it is protected from environmental influences and stored until it is examined.
An appropriate device for the implementation of this method consists of a urine collector and a filter cartridge which is fastened to the collector by a spring catch and can be detached after the urine has been passed through the filter, and connected liquid-tight with a storage vessel containing the solvent.
