Description

Laboratory bench with precipitation inhibition and reaction homogeneity enhancement function Technical Field The invention relates to a laboratory bench with functions of sediment inhibition and reaction uniformity enhancement, which can adopt different shaking effects on reagents with different volumes, belongs to the technical field of experimental equipment, and particularly relates to a laboratory bench which can drive a large bottle of reagent to shake in a small amplitude by the reciprocating rotation of a bottom coil shaft, prevent sediment from generating and ensure stable reagent properties, and drive a test tube to shake in a large amplitude by the combination of the reciprocating rotation of a round roller winding transmission shaft, so that the reagents are mixed rapidly and fully and the experimental reaction uniformity is improved. Background In scientific research and experimental scenarios, precise mixing of reagents is critical to obtaining reliable results. The traditional test tube shaking device is single in operation flow and only focuses on the mixing of the reagents in the test tube. The experimenter directly adds the reagent taken out from the big bottle into the test tube and then carries out the mixing operation, but in the practical situation, the big bottle reagent is influenced by gravity and component characteristics in the long-term standing process, layering is very easy to occur, for example, some solutions containing solutes with different densities, light components float upwards and heavy components sink, when the reagent is extracted from the big bottle, the extraction positions are different, the concentration of the obtained reagent and the proportion of the components are different, even if the existing device can fully mix the liquid in the test tube, the problem of non-uniformity exists due to the initially taken reagent, the final experimental data still generates deviation, the credibility of the experimental result is reduced, the repeatability is poor, and the conditions seriously obstruct the progress and the accuracy of research in the field of strict reagent precision requirements such as drug research and chemical analysis.
