Abstract
The utility model discloses a chromatographic column for a laboratory, which comprises a column body and a piston, wherein the lower part of the column body is provided with a filter structure; the outer side of the upper end of the column body is provided with an outwards extending convex edge; the outer side of the column body is provided with uniform scales axially; and the column body and the piston are independent with each other and are matched and connected with each other through a standard grinding port. The chromatographic column for the laboratory has the benefits that: firstly, the column body is made of medical-grade polyethylene and polypropylene which do not combine with biomolecules and is low in solubility, and the column is not easy to collide to be damaged when the chromatographic column is repeatedly cleaned and used; secondly, the column body is provided with the scales, so that column packing is convenient, and the position of certain chromatography colored tape at different time points can be marked conveniently; and thirdly, the column body and the piston are separately arranged, so that the inner wall of the lower end of the column body can be cleaned, different piston structures can be conveniently replaced at the same time, and flowing speed is convenient to control.
Description
Technical field
The utility model relates to a kind of chromatographic column, relates in particular to a kind of laboratory and uses chromatographic column.
Background technology
The laminate post is that material is carried out one of separator the most frequently used in the separation and purification process.Existing chromatographic column is a glass column often, comprises cylinder and piston, and the core of piston generally is to make for polytetrafluoroethylene (PTFE), can not be coated with vacuum grease like this; With the drawing-down of glass tube lower end, the good pipe of cover the preceding paragraph elasticity, pipe adopt to be made the polyethylene of most of solvent inertia, again with screw clamp control speed besides.The shortcoming of prior art is: (1) cylinder is a glass column, and repeated washing and use repeatedly possibly breaks up easily during use; (2) cylinder does not have scale, needs operating personnel to estimate by rule of thumb or other tolerance work is measured, and is cumbersome; (3) cylinder bottom and piston or pipe are structure as a whole, and so both can't effectively clean the inwall of chromatographic column core lower end, also because chromatographic column lower part outlet caliber is less, are caused whole chromatographic column unavailable and bump easily to break simultaneously.
Summary of the invention
The purpose of the utility model is for overcoming the deficiency of above-mentioned prior art, providing a kind of laboratory to use chromatographic column.
For realizing above-mentioned purpose, the utility model adopts following technical proposals:
Chromatographic column is used in a kind of laboratory, comprises cylinder and piston, and the bottom in the cylinder is provided with filtration, and the outside, upper end of cylinder is provided with overhanging convex edge; The cylinder outside along cylinder axis to being provided with uniform scale; Independently of one another and cooperatively interact through the standard ground and to be connected between cylinder and the piston.
Said cylinder is processed by the polypropylene or the polyethylene of medical grade.
Said filtration is a cotton layer.
The numerical value of said scale increases progressively from the bottom to top.
The length of said cylinder is 6-16 centimetre.
The diameter of said cylinder is 0.5-2.5 centimetre.
" independently of one another " refers to the two one of respectively doing for oneself, and can change, and can dismantle and assemble, and the two becomes a complete pillar through the socket connection of standard ground, and the fit system of standard ground can prevent that chromatographic solution from oozing out from interface.Overhanging convex edge can be stretched out also and can stretch out in one week along the cylinder outside in both sides, is convenient in layer post process, chromatographic column fixed.The diameter of cylinder and length ratio carried out chromatography for ease of the laboratory small sample in the present technique scheme between 1: 8 to 1: 15, adopt length and the less cylinder of diameter; Cylinder is provided with scale, and it is all more convenient with operation that operating personnel adorn post.
The beneficial effect of the utility model is that (1) cylinder adopts the medical grade polyethylene and the polypropylene that do not combine with biomolecule with low solubility to process; Clean repeatedly and be difficult for breaking pillar when using; (2) cylinder is provided with scale, is convenient to adorn post or different time points is carried out mark to the position of certain chromatography colour band; (3) cylinder separates setting with piston, can know clean cylinder lower end inwall, is convenient to simultaneously change different piston structures, is convenient to control flow velocity.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein 1. cylinders, 2. piston, 3. cotton layer, 4. scale, 5. convex edge, 6. standard ground.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1, chromatographic column is used in a kind of laboratory, comprises cylinder 1 and piston 2, and cylinder 1 is processed by the polypropylene of medical grade, and the bottom in the cylinder 1 is provided with filtration---cotton layer 3, and the outside, upper end of cylinder 1 is provided with overhanging convex edge 5; To being provided with uniform scale 4, scale 4 serves as that milliliter is calculated with each big lattice along cylinder axis in cylinder 1 outside, and its numerical value increases progressively from the bottom to top.The outside of cylinder 1 lower end is provided with the standard ground, and piston 2 upper inner are provided with the standard ground that fit with it cooperates, and is independently of one another and cooperatively interact through the standard ground and to be connected to become a complete chromatographic column between cylinder 1 and the piston 2.
The length of said cylinder 1 is 8 centimetres, and the diameter of cylinder 1 is 0.8 centimetre.
