Description
Technical field
The utility model relates to a kind of experimental provision, specifically, relates to a kind of experimental provision for quantitative analysis of chemical.
Background technology
Quantitative chemical analysis refers on qualitative analysis basis and structural analysis basis measures the content of the relevant composition in material.The quantitative analytical instrument often used has: high performance liquid chromatograph, gas chromatograph, spectrophotometer, conventional glass apparatus (beaker, graduated cylinder, glass bar, volumetric flask etc.), sky equality.
But various quantitative analytical instrument is only applicable to being used alone, often seems in disorder when being combined together use, can not coordinate fully mutually.
Utility model content
The technical problem that the utility model solves is to provide a kind of experimental provision for quantitative analysis of chemical, the quantitative analytical instrument that part is used alone can be used in combination, and then effectively improve the efficiency of experimentation, shorten experimental period.
Technical scheme is as follows:
For an experimental provision for quantitative analysis of chemical, comprise fixed mount, table top and measurer; Described fixed mount comprises support bar, limiting through hole, steady pin and base, and the end winding support of described support bar is on described base, and described limiting through hole is opened on described support bar, and described steady pin is arranged in described limiting through hole; Described table top has through hole, and described support bar is inserted in described through hole, and described table top has groove and hole clipping near the position of end, and described groove is connected with described hole clipping; Described measurer comprises funnel, sebific duct, pipette and rubber plug, and the two ends of described sebific duct connect described funnel and described pipette respectively, and the two ends of described pipette connect described sebific duct and described rubber plug respectively; Described funnel is placed in described hole clipping.
Further: the profile of described hole clipping is truncated cone-shaped or cylindrical.
Further: described rubber plug is provided with blind hole, and described pipette is inserted in described blind hole.
Compared with prior art, the utility model technique effect comprises: use of the present utility model, the quantitative analytical instrument that part is used alone can be used in combination, and then effectively improve the efficiency of experimentation, shorten experimental period.
Accompanying drawing explanation
Fig. 1 is the structural representation for the experimental provision of quantitative analysis of chemical in the utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, be structural representation for the experimental provision of quantitative analysis of chemical in the utility model.
Structure for the experimental provision of quantitative analysis of chemical comprises: fixed mount 1, table top 2, measurer 3.Wherein, the structure of fixed mount 1 comprises: support bar 11, limiting through hole 12, steady pin 13, base 14, and the end winding support of support bar 11, on base 14, support bar 11 has limiting through hole 12, and steady pin 13 is arranged in limiting through hole 12.Table top 2 has through hole, and support bar 11 is inserted in through hole, and have groove 21 and hole clipping 22 in the position near end, groove 21 is connected with hole clipping 22; The profile of hole clipping 22 is truncated cone-shaped or cylindrical, and truncated cone-shaped is convenient to the profile coordinating funnel 31.The structure of measurer 3 comprises: funnel 31, sebific duct 32, pipette 33 and rubber plug 34, and the two ends of sebific duct 32 connect funnel 31 and pipette 33 respectively, and pipette 33 two ends are connection rubber tube 32 and rubber plug 34 respectively; Rubber plug 34 is provided with blind hole, and pipette 33 is inserted in blind hole.Funnel 31 is placed in hole clipping 22, and sebific duct 32, pipette 33 and rubber plug 34 dangle naturally.
During use, first utilize limiting through hole 12, height that steady pin 13 adjusts table top 2, measured amounts chemicals is poured in funnel 31, after quiescent setting, chemicals is deposited in pipette 33, because the density of heterogeneity is different with color in chemicals, occurs layering, scale according to pipette 33 calculates the volume of heterogeneity in chemicals, the ratio of quantitative analysis of chemical medicine.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
