FIELD: physics, measurement.
SUBSTANCE: invention refers to technologies of manufacturing, testing and application of medicinal and biologically active substances and can be used for high-accuracy precision feeding of solutions, in particular water-basedones. Dropping cluster, which is a source of precision liquid feeding, is generated in gas medium purified of unwanted condensation centres, however containing soluble microparticles suspension of medicinal or biologically active substance.
EFFECT: precision feeding of solution in amount of microlitre parts per million with concentration of active substances determined by size of microparticles used as condensation nuclei.
