Abstract

The invention discloses an automatic reagent distribution device. The device comprises a sterile positive pressure/negative pressure system, a working solution sample injection unit, a diluent sampleinjection unit, an electric option valve unit, a liquid separation unit and an XY displacement objective table unit, wherein the sterile positive pressure/negative pressure system is used for providing precise pre-pressure for the working solution sample injection unit and the diluent sample injection unit, the working solution sample injection unit and the diluent sample injection unit are connected with a liquid inlet of the liquid separation unit, the electric direction selecting valve unit is arranged between the diluent sample injection unit and the liquid separation unit, a liquid outletof the liquid separation unit is located above the XY displacement objective table unit, the liquid separation unit can move in the Z-axis direction, and the XY displacement objective table unit canmove in the X-axis direction or the Y-axis direction. The device is advantaged in that through optimal design and cooperation of all the structures, any solubility of the reagents can be generated inone step in a full-automatic, rapid, accurate and on-demand mode, and various reagents can be combined at will in proportion.

Description

technical field [0001] The invention belongs to the technical field of reagent distribution, and in particular relates to an automatic reagent distribution device. Background technique [0002] At present, the preparation of concentration gradient solutions is one of the most basic operations in biochemical experiments. In cell experiments and drug screening experiments, reagents such as biomolecules and drugs with different concentrations have great differences in the behavior and toxicity of cells. Therefore, when investigating the effects of different concentrations of biomolecules and drug doses on cell behavior and toxicity, it is necessary to prepare a set of target solutions with gradient distributions. However, the traditional artificial concentration gradient preparation method requires accurate calculation, weighing, and multiple dilutions and mixings of the solution, requiring many reagent containers and cumbersome operations, and the cumbersome operation steps ar...
