Microanalysis capillary system

摘要

The microanalysis capillary system is a micro test system for qualitative and quantitative tests of liquids and particulate constituents thereof, especially of body fluids in the fields of science and medicine. It is based on a transparent, sterile capillary tube which fills automatically through capillarity and has an inner wall coated with reagent, a defined volume and flat bottom and top surfaces the depth of which is chosen in such a way that differentiation of individual particles of the material being tested is possible, if required (monocellular layer). Multiple tests can be carried out by parallel arrangement of several capillary tubes provided with a common detachable inlet which breaks off when the front and rear caps of the protective covering are compressed. The preparation and the analysis take place after removal of the sample, for example by means of an upstream puncturing cannula in the capillary tube which represents a sterile enclosed system after cementing of the ends as a protection against external influences, which system is surrounded by a protective cover which can be written on. Analysis is predominantly via optical, microscopic and photometric methods and via methods of fluorescence technology.
