Description
Technical field
The utility model relates to experimental instrument field, in particular to one kind can make pipette tips carry out SPE column and pin type filter membrane
Just pressing through the connector of column.
Background technique
The mode of mechanical continuous positive pressure Solid Phase Extraction is carried out at present, and refering to fig. 1-2, general column of crossing is inserted using column inserted link
It in the pipe for entering SPE column, and carries out positive pressure and crosses column, be not disposable, institute because SPE column is affixed to above instrument
It goes to clean to need to expend time and other cleaning structures.And it just needs if necessary to cross pin type filter membrane as shown in Fig. 2, handle
SPE column insertion insertion pin type filter membrane normal could cross film, be then directly inserted into inside SPE column with column inserted link, then carry out positive pressure
Liquid is crossed, SPE column is all affixed to above instrument, and a kind of solvent is crossed column and is accomplished to before next solvent, and SPE column requires to carry out
Cleaning, not so will cause cross contamination.
To solve the above-mentioned problems, this case is given birth to therefrom.
Utility model content
Pipette tips can be made just to be pressed through column to SPE column and pin type filter membrane the purpose of this utility model is to provide one kind to connect
Head can be adapted to pipette tips, and quickening just presses through column efficiency, have the characteristics that disposable, avoid cross contamination, the saving time and
Cleaning cost, and in the case where needing pin type membrane filtration, can equally be adapted to pin type filter membrane.
To achieve the goals above, the technical solution of the utility model is as follows:
A kind of connector for making pipette tips just pressed through column to SPE column and pin type filter membrane, it is characterised in that: the connector tool
There is the ladder section of upper, middle and lower three, connector upper section forms flange, and flange is connected to above the nozzle of SPE column, the insertion of connector middle section
In the pipe of SPE column, the outer diameter in connector middle section is identical as internal diameter in the pipe of SPE column, forms sealing, and connector lower section is designed as cooperation needle
The female Luer of formula filter membrane socket；
The connector is opened up through the rifle hole of three ladder sections, and rifle hole is inserted into for pipette tips, and solvent is flowed out from rifle hole.
Further, the rifle hole is funnel-shaped.
Further, annular convex platform is formed on the hole wall in the rifle hole.
Further, the lower edge in the connector middle section forms knuckle.
After adopting the above scheme, in the pipe of the middle section insertion SPE column of the utility model, sealing is formed, the convex of upper section is passed through
Edge is connected to above the nozzle of SPE column, completes installation, next, after the direct imbibition of pipette tips in the rifle hole of pipette tips insertion connector,
It carries out directly just pressing through column.It produces connector and uses Shooting Technique, it is cheap, can be disposable for pipette tips, it does not need clear
It washes, so saving the program and cleaning equipment of cleaning, protects environment, and whole process speed is fast, it is high-efficient, it is most important that
It can effectively prevent cross contamination；The connector lower section is designed as female Luer, can with pin type filter membrane cooperation, sealing, that is, can reach
The effect of filtering.
The utility model is described further below in conjunction with drawings and the specific embodiments.

Specific embodiment
The connector that one kind that the utility model discloses can make pipette tips just pressed through column to SPE column and pin type filter membrane, refering to
Fig. 3-5, the connector 1 have a ladder section 11 of upper, middle and lower three, and 12,13, connector upper section 11 forms flange 111, and flange 111 supports
It connects above the nozzle 21 of SPE column 2, connector middle section 12 is inserted into the pipe of SPE column 2, outer diameter and the SPE column 2 in connector middle section 12
Internal diameter is identical in managing, and forms sealing, and connector lower section 13 is designed as the female Luer of cooperation 4 socket of pin type filter membrane；Female Luer, can
When needing to arrange in pairs or groups pin type filter membrane 4 with the direct grafting of 4 socket of pin type filter membrane and sealing, that is, it can reach the effect of filtering.
The connector 1 is opened up through the rifle hole 14 of three ladder sections, and rifle hole 14 is inserted into for pipette tips 3, and solvent is flowed from rifle hole 14
Out.The middle section 12 of the utility model is inserted into the pipe of SPE column 2, is formed sealing, is connected to SPE column 2 by the flange 111 of upper section
The top of nozzle 21, complete installation, next, pipette tips 3 are inserted into the rifle hole 14 of connector 1 after the direct imbibition of pipette tips 3, carry out straight
It connects and just presses through column.In the preferred embodiment, the rifle hole 14 is funnel-shaped, plays the role of firm and pipette tips 3 is facilitated to be inserted into.
Annular convex platform 141 is formed on the hole wall in the rifle hole 14, when pipette tips 3 are inserted into rifle hole 14, annular convex platform 141 can
The effect that same O-ring equally seals is played in splicing position.
In order to advanced optimize structure, the lower edge in the connector middle section forms knuckle 121, prevents from inserting when connector 1
When entering in the pipe of SPE column 2, the outer diameter in middle section 12 can wear tube wall.
The above are only specific embodiments of the present invention, not to the restriction of the protection scope of the utility model.It is all according to
The equivalent variations that the mentality of designing of this case is done each falls within the protection scope of this case.
