Magnetic stirring device for drug analysis

Abstract

The invention discloses a magnetic stirring device for drug analysis. The magnetic stirring device comprises a magnetic stirrer; a stirring shell is arranged in a beaker; the top of the stirring shellis connected with a stirring cylinder; liquid leakage holes are formed in the outer sides of the stirring shell and the stirring cylinder; a multi-point stirring piece for stirring a medicine solution in the beaker at multiple positions is arranged in the stirring shell; the top of the beaker is connected with a clamping piece for clamping the beaker; the clamping piece is connected with the topof a water bath kettle; the top of the stirring cylinder is connected with a lifting piece for lifting the stirring cylinder. The magnetic stirrer is used for stirring the medicine solution; a medicine is placed in the beaker, meanwhile, the arranged multi-point stirring piece is placed in the stirring shell, and under the stirring effect of the magnetic stirrer, the multi-point stirring piece stirs in the stirring shell, multi-point stirring of a solution in the beaker is conveniently achieved; meanwhile, the top of the beaker is clamped through the arranged clamping piece, and shaking of thebeaker during water bath heating is reduced.

Description

technical field [0001] The invention relates to the technical field of stirring devices, in particular to a magnetic stirring device for drug analysis. Background technique [0002] Magnetic stirrer is a laboratory instrument used for liquid mixing. It is mainly used for stirring or simultaneously heating and stirring low-viscosity liquid or solid-liquid mixture. The magnetic field pushes the magnetic stirring bar placed in the container to run in a circle, so as to achieve the purpose of stirring the liquid. With the heating temperature control system, it can heat and control the sample temperature according to the specific experimental requirements, maintain the temperature conditions required by the experimental conditions, and ensure The liquid mixing meets the experimental requirements. During the drug analysis, the magnetic stirring method is used to facilitate the drug solution to be fully stirred. [0003] There is a heated magnetic stirrer on the market, which uses...

Problems solved by technology

[0003] There is a heated magnetic stirrer on the market, which uses water bath heating to heat the stirred beaker, and at the same time, under the magnetic force of the magnetic stirrer, the stirring bar placed inside the beaker can be used to stir the solution inside the beaker , but when the existing magnetic stirrer is stirring, the stirring bar placed inside the beaker is under the action of the magnetic field formed at the bottom of the stirrer, the stirring bar is adsorbed and rotated, and a stirring water column is formed inside the beaker, and the stirring water column formed by the stirring bar is in the beaker At the center vertical line, the stirring water column drives other drug solutions inside the beaker to stir, and the stirring water column formed by the stirrer exists alone in the center of the beaker, which is not conducive to uniform stirring of the drug solution deviated from the center vertical line of the beaker. Water bath heating type, the water vapor with higher temperature generated makes the beaker placed inside the water bath shake, so that the stirring water column generated by the stirring bar is shifted, which is not convenient for the drug solution in the beaker to be stirred under the stirring water column formed by the stirring bar. To this end, we propose a magnetic stirring device for pharmaceutical analysis
