The physics principle of registration immune reaction by light scattering methods is concerned. The operation of laser nephelometry for measuring antigen-antibody reaction is described. The technique of obtaining diagnostic and immune reactions of interaction latex agglutination for diphtheria determination is described.

Device for registration of bacterial cells it is possible to examine as an information task which is characterized by a priori vagueness of moment of appearance of prototype system in the area of their registration. These reasons do not allow to provide exactness measuring on the base of measuring charts, functioning of which is provided structurally, and require the program hardware methods of measuring. An effective decision of this task is possible subject to condition application of the adaptive, program-driven methods, realized on the base of the fast-acting specialized charts of high integration. A new device for registration of bacterial cells in liquid medium after the changes of them size distributing is described. Procedure of registration of bacterial cells consists in dissociating of signal from noises, amplitude and duration measurement of the proper electric impulses. The process of registration particles in real-time imaging the screening on monitor of the personal computer. The developed software allows estimating the size distributing of the explored objects and their concentration in a liquid medium in 3D-imaging. There possibilities of device from registration and visualization of bacterial cells of different nature are presented.

Parameters of filtration ofliquid solutions used in drugs production in pharmaceutics is considered in the paper. The devices intended for checking the content of microparticles in 4 dimension bands simultaneously in deionized water and injection solutions in pharmaceutics production are described. The results ofcontrol the purity in solutions glucose are presented.
