Abstract
The utility model provides a pipette tip which is matched with a pipette in use and is formed by a tip body and a port portion. The tip body is provided with a suction port, the tip body and the port portion are in threaded connection or are integrated, and the tip body is connected with the pipette through the port portion. Compared with the prior art, the pipette tip has the advantages that the problem that two or three existing pipette tips are sleeved together for experiments during experiment sample extraction and may release is solved, sample material waste is effectively avoided, sample pollution possibility is reduced, and experiment efficiency is improved.
Description
[technical field]
The utility model relates to a kind of pipettor gun head.
[background technology]
at biochemical test, in the liquid state of medical test or semi liquid state sample extraction process, sample is generally longer from being drawn into the time that is transported to laboratory, often distance arrangement is extracted also needs a period of time, therefore during this period of time sample (for example blood sample) easily becomes thick or is frozen into piece, and be difficult for heparin tube is tilted so that blood sample flows to the mouth of pipe and draws in the sample extraction process, and adopt existing two or three existing pipettor gun heads extraction sample that is nested together, situation about coming off may appear, cause wasting sample material, the while contaminated sample, even cause the failure of an experiment.
[utility model content]
The utility model is intended to solve above-mentioned problems of the prior art, proposes a kind of pipettor gun head.
Described pipettor gun head and pipettor are used in conjunction with, and rifle head body and interface portion, consist of.Wherein, described rifle head body is provided with a suction inlet; Described rifle head body adopts and is threaded or is wholely set with described interface portion, and described rifle head body is connected with described pipettor by described interface portion.
Preferably, the length of described rifle head body is 12-13 centimetre.
Preferably, the length of described rifle head body is 12.5 centimetres.
Preferably, described rifle head body is conical.
Preferably, the cone angle of described rifle head body is 20 °-25 °.
The pipettor gun head that the utility model proposes compared with prior art, that can avoid adopting two or three existing pipettor gun heads to be nested together test in extracting liquid state or semi liquid state experiment sample process and may occur comes off, the sample material of effectively avoiding waste, reduce simultaneously the possibility of sample contamination, improved conventional efficient.
[description of drawings]
Fig. 1 is the pipettor gun head schematic diagram of the utility model one embodiment.
[specific embodiment]
Below in conjunction with specific embodiment and accompanying drawing, the utility model is described in further detail.Below describe embodiment of the present utility model in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or the element with identical or similar functions from start to finish.Be exemplary below by the embodiment that is described with reference to the drawings, only be used for explaining the technical solution of the utility model, and do not should be understood to restriction of the present utility model.
In description of the present utility model, term " interior ", " outward ", " vertically ", " laterally ", " on ", orientation or the position relationship of the indications such as D score, " top ", " end " be based on orientation shown in the drawings or position relationship, it is only the utility model rather than require the utility model, with specific orientation structure and operation, therefore not should be understood to restriction of the present utility model for convenience of description.
The utility model provides a kind of pipettor gun head, with pipettor, is used in conjunction with, and is used for the extraction of biochemistry liquid state or semi liquid state sample.
As shown in Figure 1, described pipettor gun head consists of rifle head body 100 and interface portion 200, described rifle head body is provided with a suction inlet 101, described rifle head body 100 is connected with described pipettor by described interface portion 200, described rifle head body 100 can be integrated setting with described interface portion 200, also can adopt other connected mode such as be threaded.
Preferably, the length of described rifle head body 100 is 12-13 centimetre.Preferably, the length of described rifle head body is 12.5 centimetres.
Preferably, described rifle head body 100 is conical.Those skilled in the art will be understood that taper shape is a kind of decision design mode of described rifle head body 100 shapes, and described rifle head body 100 also can adopt such as the conical design that waits other shape of class.Preferably, when described rifle head body 100 adopted conical design, the cone angle size of described rifle head body 100 was 20 °-25 °.
The pipettor gun head that use the utility model proposes can be used for extracting other biological specimens such as whole blood DNA.
For example, the pipettor gun head that at first will the utility model proposes is connected with pipettor, more described pipettor gun head is put in the heparin tube bottom, stirs, draws in heparin tube after thawing the whole blood that is thickness or grumeleuse shape, carries out subsequent experimental.
And for example, the pipettor gun head that the utility model proposes is put in centrifuge tube bottom, draw lightly saliva sample in centrifuge tube in required cell therefor or cryopreservation tube, as extracting organism DNA.
For another example, the pipettor gun head that the utility model proposes also can be used for connecing bacterium in the Agrobacterium re-activation.Particularly, the Agrobacterium that is stored in-80 ℃ is activated and grows single bacterium colony in the solid culture of cultivating after, dip a single bacterium colony with the described pipettor gun head after sterilizing, then single bacterium colony being sent to piping and druming in the culture medium of the conical flask that is contained in 30ml, 50ml or 100ml of having cultivated several times, completes re-activation and connects the bacterium process.
The pipettor gun head that the utility model proposes is used in darker container and draws than the liquid state of thickness or semi liquid state biological specimen, that can avoid adopting two or three existing pipettor gun heads to be nested together and test and may occur comes off, the sample material of effectively avoiding waste, reduce simultaneously the possibility of sample contamination, improved conventional efficient.
Although the utility model is described with reference to current preferred embodiments; but those skilled in the art will be understood that; above-mentioned preferred embodiments only is used for explaining and the explanation the technical solution of the utility model; and not be used for limiting protection domain of the present utility model; any within spirit of the present utility model and principle scope; any modification of doing, equivalent replacement, distortion, improvement etc., within all should being included in claim protection domain of the present utility model.
