Description
Technical field
The utility model belongs to chemical experiment tools range, and particularly the micro-bilayer getting extraction process of a kind of chemical laboratory solid phase stirs water bath device.
Background technology
In the experiment of gas-chromatography, when carrying out trace organic substance analysis in complex matrices, commonly use the micro-processing method of getting extraction of solid phase.The method requires that the process of sample needs at a certain temperature, as 50 ± 1 DEG C, usually will use water-bath and carry out the constant of holding temperature; In addition, because testing sample is sealed in sample bottle, and in order to improve the sensitivity of method, usually add sodium chloride in sample substrate, traditional individual layer agitator can not maintain even, the stable state of the sample after salt adding; Therefore interior agitating mode must be adopted to maintain even, the stable state of the sample after salt adding, and this device adopts the double-deck water bath device that stirs can realize steady temperature simultaneously and seal the requirement of stirring.
Utility model content
The purpose of this utility model is even, the stable state that can not maintain the sample after salt adding for individual layer agitator traditional in prior art, the deficiency of the requirement of steady temperature and sealing stirring can not be realized simultaneously, and provide the micro-bilayer getting extraction process of a kind of chemical laboratory solid phase to stir water bath device, it is characterized in that, at water bath internal fixtion base plate, sample bottle is positioned on base plate, bottleneck is blocked by cover central hole, large stirring rod is placed on below base plate, and little stirring rod is positioned in sample bottle; Thermometer inserts from the side opening of cover plate, and this device is positioned on magnetic stirring apparatus.
Described cover plate is glass material, forms a complete circle cover plate by two and half closing disk shapes; Two semicircular center has semicircle orifice, and two semicircle orifices synthesize a complete circular hole; Described side opening is arranged on any one half closing disk.
Described water bath is coloured glaze material.
Described base plate is coloured glaze material, and shape is trapezoidal cylinder; Cylindrical wall symmetrical openings below, form four foots, four-footed width is 1/8 of place circular perimeter;
The beneficial effects of the utility model are by outer magnetic stirring apparatus, and little stirring rod in sample bottle, can maintain sample even; Large stirring rod stirs and current can be made fully to flow and keep bath temperature to stablize; The requirement of when chemical laboratory solid phase is micro-gets extraction process, steady temperature and sealing being stirred can be met simultaneously; Improve the micro-precision of getting the processing method of extraction of solid phase.
Accompanying drawing explanation
Fig. 1 is the double-deck schematic diagram stirring water bath device.
Fig. 2 is base arrangement schematic diagram.
Detailed description of the invention
The utility model provides the micro-bilayer getting extraction process of a kind of chemical laboratory solid phase to stir water bath device, is explained below in conjunction with drawings and Examples.
Figure 1 shows that the double-deck schematic diagram stirring water bath device.In figure, at the water bath 8 internal fixtion base plate 3 of coloured glaze material, sample bottle 9 is positioned on base plate 8, and sample bottle 9 bottleneck is blocked by cover plate 7 centre bore 5, plays fixation; Large stirring rod 2 is placed on below base plate 3, and little stirring rod 1 is positioned in sample bottle 9; Thermometer 4 inserts from the side opening 6 of cover plate, and this device is positioned on magnetic stirring apparatus.
Wherein, cover plate 7 is glass material, forms a complete circle cover plate 7 by two and half closing disk shapes; Two semicircular center has semicircle orifice, and two semicircle orifices synthesize a complete circular hole 5; Described side opening 6 is arranged on any one half closing disk.Described base plate 3 is coloured glaze material, and shape is trapezoidal cylinder; Cylindrical wall symmetrical openings below, form four foots, four-footed width is 1/8 of place circular perimeter; Be placed on the large stirring rod 2 below base plate 3, drive water body medium in water bath 8, maintain bath temperature balanced; Little stirring 1 rod is positioned in sample bottle 9, and in blender jar, sample is even, obtains desirable testing sample.
Embodiment
This device is divided into three parts:
One is water bath: coloured glaze material, diameter 150mm, high 75mm;
Two is base plates: coloured glaze material, and upper plate adds four foots, upper board diameter 60mm, and foot is in same disc, and disc diameter is 100mm, and four-footed width is 1/8 of place circular perimeter, and bottom plate heights is 8mm;
Three is cover plates: glass material, is made up of two semicircles, a two halves circle composition complete circle, diameter 160mm, home position punches, centre bore aperture 16mm, half circular cover middle position is beaten the side opening in 16mm aperture wherein, holes footpath distance is 40mm.
Because bottom plate heights is through accurate Calculation, this device is positioned on magnetic stirring apparatus, by outer magnetic stirring apparatus, little stirring rod in sample bottle can be made fully to stir, and maintains sample even; Base plate and four pin shapes designs, due to jagged, when large stirring rod stirs, can make current fully flow and keep bath temperature to stablize.
When this device is generally used for GC-MS Analysis, sample is had to solid phase is micro-gets the situation that extraction has requirement.The experiment that my company technique central laboratory adopts SPME to carry out sample pretreatment mainly contains: the analysis etc. of micro-plasticizer components in the analysis of Fructus Hordei Germinatus aroma substance in the analysis of aging aldehyde material in the analysis of hops aroma component in beer, beer, beer, water-based sample.
