Laboratory device Vortex V-1 is constructed by using the eccentric mechanism for sample mixing placed in tubes. The Vortex has two modes of operation: continuous or periodical, when vortex cap is pressed with a tube. Vortex V-1 can be used in a variety of laboratory applications including general test tube mixing, mixing tissue samples and vortex cells suspensions, mixing chemical reagents, ect. Vortex V-1 is applicable in all areas of laboratory research & education in biotechnology, molecular biology, biochemistry, cell-biochemistry, microbiology, chemistry, cytology, cytochemistry, medicine, gene engineering, PCR-diagnostic, food quality analysis.
