Abstract
The utility model provides a column chromatographic device capable of easily recovering experimental waste, and aims to solve the problem that waste liquor and waste residues left in a glass chromatographic column in a column chromatographic preparation and organic matter separation experiment in the prior art are difficultly dumped, and are usually inevitably flushed into a sewer to pollute the environment and harm personal health. The column chromatographic device comprises an upper section of chromatographic column body and a lower section of chromatographic column body, wherein the upper section of chromatographic column body is a chromatographic column body of which the lower end is provided with a standard outer frosted connector; the lower section of the chromatographic column is a part of which the upper end is provided with a standard inner frosted connector matched with the standard outer frosted connector of the upper section and a piston valve; and the upper and lower sections of column bodies are combined and split through the outer frosted connector and the inner frosted connector.
Description
Technical field
The utility model relates to a kind of column chromatography technical field, a kind of specifically column chromatography device.
Background technology
In " preparation of column chromatography and organic separation " experimental implementation, eluant, eluent adopts chloroform/pure system usually, specifically is to use chloroform/methanol solution to be eluant, eluent.The eluent waste liquid is the waste liquid that contains the red and bromocresol green of chloroform, methyl alcohol and trace methyl.Because chloroform, methyl alcohol are not only poisonous, and saturated vapor pressure is high, the saturated vapor pressure of chloroform (kPa): the saturated vapor pressure saturated vapour pressure (kPa) of 13.33 (10.4 ℃) methyl alcohol: 13.33 (21.2 ℃); As deal with improperly and can work the mischief the environment person.
Therefore, must all reclaim the centralized management Unified Treatment for experiment eluent waste liquid and the waste residue that contains eluent.Current experiments chamber glass chromatography column is the chromatographic column of one, and it comprises: chromatographic column cylinder 1, piston valve 4, piston valve dripping hole 5 and chromatographic column minim pipette 6.The chromatographic column cylinder is long, and bubble is not stayed in requirement filling densifications such as the absorbent cotton of layering filling, silica gel, extra large sand in the post layer, after experiment is accomplished; The adsorbent that is soaked into by the chloroform/methanol eluant, eluent in the chromatographic column owing to flowability is poor, remains in the chromatographic column cylinder to be difficult to topple over; Even can not topple over out by beaing vibrations, often because of undue force makes chromatographic column broken, have to sometimes wash out these waste materials by washing from the beginning in a large number; So, can cause the waste liquid load to increase, even waste liquid is poured sewer pipe with flushing unavoidably; The saturated vapor pressure of chloroform is high, and chloroform is as organic solvent, and it is quite serious that the corrosion of the drainage pipeline of macromolecular material is destroyed; Can make pipe deforming, weld cracking, cause the environmental pollution public hazards simultaneously.Therefore must reclaim, forbid to flow into drainage pipeline.
Summary of the invention
To the problem that prior art exists, liquid and waste slag produced whole recovery of experiment usefulness are dealt carefully with, only lean on everybody to note checking on, stress that sense of responsibility is not enough, and should lean on complete process unit condition guarantee.For this reason, the utility model provides a kind of column chromatography device that is easy to make the liquid and waste slag produced recovery of " preparation of column chromatography and organic separation " experiment.
The column chromatography device that is provided of the utility model comprises upper and lower two-stage chromatography column cylinder.Last stage chromatography column body is the chromatographic column cylinder of the outer frosted connector of lower end band, and hypomere is the part that the upper end has interior frosted connector and piston valve.
The utility model have following characteristics:
1, the convenient recovery tested the liquid and waste slag produced pollution of avoiding, and has good social benefit;
2, avoid the volatile virulent organic solvent waste liquid infringement that personal safety causes to environment of " preparation of column chromatography and organic separation " experiment eluant, eluent;
3, this device preparation method is simple, and reaching Figure of description to specifications can make.
Description of drawings
Fig. 1: column chromatography apparatus structure sketch map;
Fig. 2: the chromatographic column structural representation of prior art.
Among the figure: 1, chromatographic column epimere cylinder, 2, outer frosted connector, 3, interior frosted connector, 4, chromatographic column hypomere cylinder, 5, piston valve, 6, the piston valve dripping hole, 7, the chromatographic column minim pipette,
The specific embodiment
With reference to Figure of description the chromatographic column device of the utility model is done following detailed description below.
The column chromatogram chromatography device comprises chromatographic column epimere cylinder 1, chromatographic column hypomere cylinder 4; There is outer frosted connector 2 chromatographic column epimere cylinder 1 lower end, and there is interior frosted connector 3 chromatographic column hypomere cylinder 4 upper ends, and the lower end is a piston valve 5, piston valve dripping hole 6 and chromatographic column minim pipette 7; Outer frosted connector (2) and interior frosted connector (3) are supporting standard mouth frosted mouths, and upper and lower two sections cylinders make up or split through outer frosted connector (2) and interior frosted connector (3).
The column chromatography device of the utility model is made very simple, can make shown in the by specification accompanying drawing.When carrying out " preparation of column chromatography and organic separation " experiment, chromatographic column epimere cylinder 1 is connected with chromatographic column hypomere cylinder 4 with interior frosted connector 3 through outer frosted connector 2, carries out " preparation of column chromatography and organic separation " experiment.Experiment finishes, with chromatographic column epimere cylinder 1 and chromatographic column hypomere cylinder 4 outside frosted connector 2 separate with interior frosted connector 3 places, experiment waste material ground is discharged respectively by upper and lower two sections cylinders.
Except that the described technical characterictic of specification, be those skilled in the art's known technology.
Claims (2)
1. the column chromatography device comprises chromatographic column epimere cylinder (1), chromatographic column hypomere cylinder (4); It is characterized in that the column chromatography device has outer frosted connector (2) by chromatographic column epimere cylinder (1) lower end; It is that piston valve (5), piston valve dripping hole (6) and chromatographic column minim pipette (7) are formed that there are interior frosted connector (3), lower end in chromatographic column hypomere cylinder (4) upper end.
