specific Embodiment 1
[0034] Specific embodiment 1 of the support assembly of the present invention: the support assembly can be used to implement the heating reflux extraction method of the above-mentioned embodiment 1, including a bottle support and a condenser tube righting device, which are connected with the flask 2 (including the container containing the solvent and the sample) when in use Sample flask, solvent flask containing the same solvent), condenser tube 3, stand 5, cross clip 11 and water bath (not shown in the figure) cooperate to complete the heating and reflux extraction test, the specific form is as follows: figure 1 and figure 2 As shown, the bottle holder comprises a pair of oppositely arranged risers 6 which form the legs of the bottle holder. The vertical plate 6 is fixedly connected with the limiting plate 7 and the supporting plate 8, and the limiting plate 7 and the supporting plate 8 are arranged horizontally at intervals one above the other. The outer diameter is to avo...
specific Embodiment 2
[0037] Specific embodiment 2 of the bracket assembly of the heating reflux extraction device of the present invention: the difference between this embodiment and specific embodiment 1 is that no rubber sleeve is provided, and a rubber layer is provided on the inner wall of the centralizing ring to avoid collision between the condensation pipe and the centralizing ring. The rubber layer constitutes the cushioning layer.
