Abstract
The utility model discloses one kind to chromatograph rod structure, including cylinder, the cylinder upper end-face edge is equipped with radially projecting first flange edge, the top of the cylinder is equipped with a block, and the block lower edge is equipped with the radially projecting and second flange edge that matches with the first flange edge；One fastening piece of the first flange edge and second flange edge to match is positioned.Its dismountable flange mouth structure effectively solves the problems, such as that cleaning is difficult, and when top ground is lost, its replacement cost is relatively low.
Description
Technical field
It the utility model is related to a kind of Laboratory Instruments equipment, more particularly to a kind of structure of chromatographic column.
Background technology
Existing chromatography rod structure, in use since mark mouth is too small, it may appear that silica gel can not be poured out, and cleaning is difficult
The problem of, for the chromatographic column that column diameter is larger, problem is especially apparent.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of chromatography rod structure easy to cleaning.
Its technical problem to be solved can be implemented by the following technical programs.
One kind chromatography rod structure, including cylinder, its feature are that the cylinder upper end-face edge is equipped with radially projecting first
Flange edge, the top of the cylinder are equipped with a block, and it is radially projecting and with described that the block lower edge is equipped with one
The second flange edge that one flange edge matches；One lock ring of the first flange edge and second flange edge to match
Part is positioned.
Further as the technical program is improved, and the lock ring face of the fastening piece is equipped with groove, and the groove is used to hold
Receive the first flange edge and second flange edge of protrusion.
One of preferred embodiment as the utility model, the block are glass standard mouth.
Further as the technical program is improved, what the fastening piece linked together for two pieces through threaded connector
Semicircle ring.
The further improvement of the technical program is also served as, fritillarine is equipped with the lower chamber of the cylinder.
The further improvement of the technical program is also served as, the piston of the chromatographic column is tetrafluoro piston.
Using the chromatography rod structure of above-mentioned technical proposal, it is difficult that its dismountable flange mouth structure effectively solves cleaning
The problem of, and when top ground is lost, its replacement cost is relatively low.
Brief description of the drawings
Fig. 1 is the part schematic diagram that the utility model chromatographs rod structure；
Fig. 2 is the flange port Spring Clip schematic diagram of the utility model chromatographic column；
In figure：100 --- --- glass flange mouth 200 --- cylinder 210 --- glass flanges of glass standard mouth 110
--- --- piston 310,320 --- collar 330 --- tightens screw to fritillarine 230 to mouth 220
Embodiment
Specific embodiment of the utility model is described in further detail below in conjunction with the accompanying drawings.
Chromatography rod structure as depicted in figs. 1 and 2, the top edge of cylinder 200 is outwardly glass flange mouth 210,
200 top of cylinder is used as block equipped with a glass standard mouth 100, and the lower edge of block forms outwardly glass flange
Mouth 110.110 and 210 size of glass flange mouth is adapted, both matched through flange port card shown in Fig. 2 by the direction of arrow in figure
Circle banding links together.Wherein, which by upper and lower two semi-circular shape collars 310 and 320 and translateral tightens spiral shell
Follow closely 330 common banding positioning.
Wherein, if necessary, the groove of the flange port for receiving protrusion can be opened up on the working face on the inside of collar.
When needing dismounting, two lock rings for tightening screw 330, collar 310 and 320 pairs of glass flange mouths 110 and 210 are unclamped
Event resolves, and then convenient cleaning.
In addition, the lower chamber in cylinder 200 is also placed by fritillarine, preferably to complete filtration duty；And should
The piston 230 of chromatographic column lower part uses the design of tetrafluoro piston.
Detachable chromatographic column provided by the utility model, in addition to it effectively can solve the problems, such as to clean difficulty, beam ground
Easy lossy is also resolved, and since ground damages upper back block interchangeable, actually reduces use cost.
