Description
Technical field
The utility model relates to laboratory equipment, specifically relates to a kind of chromatographic column fixture.
Background technology
Chromatography purifying is that protein separation, plant extracts separation and purification, biological medicine purifying etc. are separated widely used technology in purge process in recent years, chromatography purification technique is especially separated with laboratory and is prepared as master, and laboratory chromatography purge process all needs the chromatographic stuffing of the material such as sephadex, polymer to be loaded into the separation and purification carrying out pretreatment or sample in the glass chromatography column of main body.And, in the chromatography purge process of laboratory, frequent needs are changed the filler be loaded in glass chromatography column and are reset, therefore, in the replacing and refitting process of filler, gripping of chromatographic column is very important link, and being fixed on of chromatographic column plays a part definitely important in the chromatography purge process of laboratory.
In existing laboratory equipment, common chromatographic column fixture is normally made up of a large-scale brandreth and the circular rod iron of five six roots of sensation, by rope or screw, chromatographic column is fixed, due to such fixture less stable, and dismounting glass chromatography column continually, be easy to the damage causing glass chromatography column, make troubles also to while reducing operating efficiency the operation of experimenter.
Utility model content
In order to solve the problem, the purpose of this utility model is to provide a kind of chromatographic column fixture so that realize chromatographic column quick, stably grip.
In order to achieve the above object, the utility model have employed following technical scheme:
A kind of chromatographic column fixture, has such feature, comprising: counter weight base, be erected at the support bar on counter weight base, and two to be arranged on support bar and the cross bar of vertical non-alignment respectively; Wherein, the projecting end of every root cross bar is equipped with the cramping body for clamping chromatographic column, and cross bar and support bar are fastenedly connected by hand tighten screw.
Further, in the chromatographic column fixture that the utility model provides, such feature can also be had: cramping body is ring-shaped clip, and the internal diameter of ring-shaped clip and the diameter of chromatographic column match.
Further, in the chromatographic column fixture that the utility model provides, such feature can also be had: ring-shaped clip is surrounded by two semicircle cutting ferrule subtends and formed, and two semicircle cutting ferrules are fastenedly connected by hand tighten screw.
Further, in the chromatographic column fixture that the utility model provides, such feature can also be had: the inner ring of ring-shaped clip is embedded with elastic tape.
Further, in the chromatographic column fixture that the utility model provides, such feature can also be had: the bottom of counter weight base is provided with several stabilizers.
The good effect that the utility model has on the basis of the above is:
The chromatographic column fixture that the utility model provides by installing the cross bar of two vertical non-alignment on support bar, and at the projecting end of every root cross bar, ring-shaped clip is set as cramping body, chromatographic column can be realized by the hand tighten screw on locking ring-shaped clip to grip fast, stably, there is simple to operate, practical and convenient advantage.
In addition, in the chromatographic column fixture that the utility model provides, two cross bars adopt hand tighten screw to connect support bar, thus can realize gripping of the chromatographic column of different length, have good versatility.
In addition, in the chromatographic column fixture that the utility model provides, the inner ring of ring-shaped clip is embedded elastic tape, can effectively prevent the chromatographic column because dismounting causes continually from damaging.
Accompanying drawing explanation
Fig. 1 is the structural representation of chromatography column fixer in embodiment of the present utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reach object and effect is easy to understand, following examples are specifically addressed the chromatographic column fixture that the utility model provides by reference to the accompanying drawings.
As shown in Figure 1, the chromatographic column fixture that the present embodiment provides comprises: counter weight base 1, support bar 2, and two cross bars 3 perpendicular to this support bar 2.In the present embodiment, support bar 2 and cross bar 3 are made by not stainless steel.
Concrete, support bar 2 is erected on the counter weight base 1 of tabular, and in the present embodiment, the bottom of counter weight base 1 is provided with several stabilizers 4.Can realize the balance adjustment at experimental site by stabilizer 4, what make chromatographic column 10 fixedly reaches optimum level.
Two cross bars 3 to be arranged on support bar 2 and vertical non-alignment respectively.Further, cross bar 3 and support bar 2 are fastenedly connected by hand tighten screw 5.Wherein, the projecting end of every root cross bar 3 is equipped with the cramping body 6 for clamping chromatographic column 10, and cramping body 6 and cross bar 3, directly for removably connecting, are fastenedly connected by hand tighten screw 7 in the junction of cramping body 6 with cross bar 3.
In the present embodiment, cramping body 6 is ring-shaped clip, and the internal diameter of ring-shaped clip and the diameter of chromatographic column 10 match.As preferred technical scheme, ring-shaped clip is surrounded by two semicircle cutting ferrule 61 subtends and is formed, and two semicircle cutting ferrules 61 are fastenedly connected by hand tighten screw 8.
In order to the damage preventing ring-shaped clip from causing chromatographic column 10 in the process of clamping chromatographic column 10, as preferred technical scheme, the inner ring of ring-shaped clip is embedded with elastic tape 9.
The chromatographic column fixture that the present embodiment provides by installing the cross bar of two vertical non-alignment on support bar, and at the projecting end of every root cross bar, ring-shaped clip is set as cramping body, chromatographic column can be realized by the hand tighten screw on locking ring-shaped clip to grip fast, stably, there is simple to operate, practical and convenient advantage.
In addition, in the chromatographic column fixture that embodiment provides, two cross bars adopt hand tighten screw to connect support bar, thus can realize gripping of the chromatographic column of different length, have good versatility.
In addition, in the chromatographic column fixture that embodiment provides, the inner ring of ring-shaped clip is embedded elastic tape, can effectively prevent the chromatographic column because dismounting causes continually from damaging.
Certainly, the chromatographic column fixture involved by the present embodiment is not merely defined in the structure in the present embodiment, any equivalent modifications of carrying out the utility model and substituting also all in category of the present utility model.
