Abstract
The utility model discloses a column chromatography device for azo. The column chromatography device comprises a liquid storing tank at the upper part and an extracting column frame at the lower part, wherein a plurality of liquid storing tubes are connected to the bottom of the liquid storing tank, an extracting column is correspondingly arranged below each liquid storing tube, the extracting columns are fixed on the extracting column frame, the liquid storing tank is internally provided with a folding sucking plate; liquid outlet holes, corresponding to the spaces among the mouths of the liquid storing tubes, are formed in the bottom plate of the sucking plate, the sectional area of each liquid outlet hole is smaller than that of the mouth of each liquid storing tube, so that diethyl ether in the liquid storing tank can slowly drip into the liquid storing tubes; and the liquid storing tubes are of burette structures, thus conveniently controlling the flow rate to finish column chromatography. As the liquid storing tank is internally provided with a plurality of liquid storing tubes, the sucking plate is used for controlling the liquid supply, and the structure of the device is simple, complicated column chromatography becomes simple and fast, the cost for labor force is saved, and the work efficiency is improved.
Description
Technical field
The utility model relates to a kind of use for laboratory equipment, refers in particular to a kind of azo and crosses column device.
Background technology
According to the extraction stages in " mensuration of GB/T 17592-2011 textile family expenses azo dyes " experimentation, need be by 4 × 20ml ether post step excessively of elution sample repeatedly in extraction column, a kind of device that continues to provide ether need to be provided, at present, in Biochemical Lab, conventionally adopt the simple and easy column device of crossing, adopt the mode that manually dripped post, and want multiple targets to carry out elution repeatedly, comparatively loaded down with trivial details.
Summary of the invention
The purpose of this utility model is to measure the drawback of extraction stages complex operation for existing azo dyes, provides a kind of azo to cross column device.
The purpose of this utility model is realized by following technical scheme: a kind of azo is crossed column device, comprise the reservoir of top and the extraction pylon of below, the connection of reservoir bottom arranges some liquid storage pipes, each liquid storage pipe is transferred correspondence extraction column is set, extraction column is fixed on and extracts on pylon, in described reservoir, be provided with folding shape pumping board, on pumping board base plate, corresponding liquid storage mouth of pipe spacing correspondence is provided with fluid hole.
In the time that reservoir is equipped with ether, pull pumping board, make fluid hole on pumping board base plate and the liquid storage mouth of pipe to upper, now, ether flows in liquid storage pipe from reservoir, thereby finally splashes in extraction column.
Described fluid hole sectional area is less than liquid storage mouth of pipe sectional area, thereby the ether in reservoir can slowly be splashed in liquid storage pipe.
Described liquid storage pipe adopts buret structure, is convenient to coutroi velocity and completes post process.
The utility model is by some liquid storage pipes are set in reservoir, and adopts pumping board to carry out the control of fluid switch, arranges by simple structure, makes the loaded down with trivial details post of crossing become simple and fast, saved labor cost, improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of azo is crossed column device, comprise the reservoir 1 of top and the extraction pylon 2 of below, reservoir 1 bottom connection arranges some liquid storage pipes 3, each liquid storage pipe is transferred correspondence extraction column 4 is set, extraction column 4 is fixed on and extracts on pylon 2, is provided with folding shape pumping board 5 in described reservoir 1, and on pumping board base plate 51, the corresponding liquid storage mouth of pipe 6 spacing correspondences are provided with fluid hole 7.
In the time that reservoir 1 is equipped with ether, pull pumping board 5, make fluid hole on pumping board base plate 51 7 with the liquid storage mouth of pipe 6 to upper, now, ether flows in liquid storage pipe 3 from reservoir 1, thereby finally splashes in extraction column 4.
Described fluid hole sectional area 7 is less than the liquid storage mouth of pipe 6 sectional areas, thereby the ether in reservoir can slowly be splashed in liquid storage pipe.
Described liquid storage pipe 3 adopts buret structure, is convenient to coutroi velocity and completes post process.
Described the utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have and in basis, ask identical or akin technical scheme, within all dropping on protection domain of the present utility model.
