Abstract
The utility model provides a column chromatography holdout device, it is including chromatography column, rubber stopper and syringe, and wherein the rubber stopper is arranged in chromatography column port portion will the chromatography column is sealed, the syringe passes the rubber stopper with the chromatography column intercommunication to take the air in the chromatography column out. The utility model has the advantages of avoid organic solvent to volatilize, organic solvent is not dirty naturally because of the action of gravity in the time of can not making the column chromatography.
Description
Technical field
The utility model relates to a kind of column chromatography device, especially in regard to a kind of holdout device of column chromatography.
Background technology
When chemical laboratory carries out column chromatography for separation; often can there is midway and need the long-time phenomenon suspended; but column chromatography proceeds to a half; if left for a long time; organic solvent volatilizees or naturally dirty naturally, is easy to " dry pillar " phenomenon to occur, when again carrying out column chromatography; be easy to alveolate phenomenon in chromatographic column can occur, do not cause column chromatography separating effect good or do not reach the effect of separation.
Utility model content
The purpose of this utility model be to provide a kind ofly organic solvent can be avoided to volatilize, when can not make column chromatography organic solvent because of the naturally dirty Zhu's chromatography holdout device of Action of Gravity Field.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of column chromatography holdout device, it includes chromatographic column, rubber stopper and syringe, wherein rubber stopper is placed in described chromatographic column port part, described chromatographic column is sealed, described syringe is communicated with described chromatographic column through described rubber stopper, and is extracted out by the air in chromatographic column.
Compared with prior art, the utility model has following beneficial effect:
One, organic solvent can be avoided to volatilize, form the phenomenon of " dry pillar ".
Two, prevent organic solvent because of Action of Gravity Field naturally dirty, simultaneously can effectively avoid producing bubble in chromatographic column.
Accompanying drawing explanation
Fig. 1 is the structural representation of column chromatography holdout device described in the utility model.
Detailed description of the invention
For the technique effect of setting forth the technology used in the present invention means further He reach, elaborate below in conjunction with drawings and Examples.
Consulting Fig. 1, is structural representation of the present utility model.In this embodiment, column chromatography holdout device, includes chromatographic column 1, rubber stopper 2 and syringe 3.Wherein rubber stopper 2 is placed in described chromatographic column 1 port part, is sealed by described chromatographic column 1, prevents the volatilization of organic solvent.Described syringe is worn 3 and is crossed described rubber stopper 2 and connect 1 with described chromatographic column and lead to, and is extracted out by the air in chromatographic column 1, to make in chromatographic column in negative pressure of vacuum, makes organic solvent can not be naturally dirty because of Action of Gravity Field.
Above-mentioned explanation fully discloses detailed description of the invention of the present utility model.It is pointed out that the scope be familiar with person skilled in art and any change that detailed description of the invention of the present utility model is done all do not departed to claims of the present utility model.Correspondingly, the scope of claim of the present utility model is also not limited only to previous embodiment.
