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.

Method and device for examining urine for particulate constituents

A method for taking and collecting sample material. A sampler is used which consists entirely, or at least at its surface or contact area, of a plastic material which is soluble in water. The sampler, after wetting and hence superficial dissolution, is brought into contact with the surface to be examined. The sample material sticks to the plastic. The sampler is removed and dissolved, whereby the sample material is collected.
