Abstract
The utility model relates to biology field auxiliary implement used, specifically a kind of townhouse formula rifle head being applicable to multichannel liquid-transfering gun, comprise multiple rifle head with branch sleeve, it is characterized in that: each rifle head is combined into a townhouse formula structure by connector, the upper inner cylinder wall of each rifle head branch sleeve is provided with multiple tracks ring wall formula protruding.The utility model overcomes suction that existing multichannel liquid-transfering gun rifle head card tightly do not cause and does not go up liquid and maybe can not draw prescribed volume liquid, and the rifle head that between rifle head, spacing difference causes can accurately not insert the problem bottom platoon centrifuge tube or 96 orifice plates, and the conventional efficient solving spacing difference initiation between rifle head reduces and finally affects the situation of experimental result.
Description
Technical field
The utility model relates to biology field auxiliary implement used, specifically a kind of townhouse formula rifle head being applicable to multichannel liquid-transfering gun, this liquid transfer gun head can not only solve the not tight problem of rifle head card, and the conventional efficient that can solve spacing difference initiation between rifle head reduces and finally affects the situation of experimental result.
Background technology
At present in Molecular Biology Lab, when using townhouse centrifuge tube or 96 orifice plates to process large batch of biological sample RNA or DNA etc. of the multiple sample of Simultaneous purification (in the experiment of quantitative PCR experiment, Enzyme-linked Immunosorbent Assay (ELASA), gene chip experiment), often use multichannel liquid-transfering gun simultaneously.Multichannel liquid-transfering gun can shorten loading time (particularly in the reaction of enzyme and Binding Capacity), ensures the uniformity of application of sample, better improves conventional efficient and ensures that experimental result is genuine and believable.But in the use procedure of multichannel liquid-transfering gun, because rifle head inwall is more smooth and do not have fixed connection apparatus between rifle head, have one or several rifle head card tight in frequent generation one group of rifle head, and the rifle head of original equidistant arrangement on rifle head box change (deviation is between 1-4 mm) being inserted into spacing after on liquid-transfering gun.Rifle head does not have clamping the liquid of liquid-transfering gun setting volume can occur to draw, the situation that even rifle head process so comes off when application of sample; Spacing between the townhouse centrifuge tube used in experiment in addition and 96 orifice plates, two holes is fixing (between general townhouse centrifuge tube and 96 hole U-shaped orifice plates, spacing is all 10 mm) substantially, and the spacing change between rifle head indivedual rifle head can occur and can accurately not insert in corresponding centrifuge tube or 96 orifice plates.Particularly at use 96 hole U-shaped orifice plate paramagnetic particle method purifying RNA and DNA, when the 96 U-shaped orifice plates in hole are placed on magnetic frame, liquid can be separated with magnetic bead, magnetic bead can form an obvious circle due to the effect of bottom magnetic frame, if the spacing between rifle head not etc., then can accurately not drawn the liquid bottom U-shaped orifice plate, and be easy to the magnetic bead being drawn onto liquid side, this can cause in RNA and DNA of purifying has magnetic bead to pollute, and affects the final result of genetic chip.Multichannel liquid-transfering gun serves uncertain factor can to experiment band with existing rifle head affects conventional efficient, and may affect final experimental result.
Utility model content
The suction that the purpose of this utility model does not tightly cause to overcome existing multichannel liquid-transfering gun rifle head card just is not gone up liquid and maybe can not be drawn prescribed volume liquid, and the rifle head that between rifle head, spacing difference causes can accurately not insert the problem bottom platoon centrifuge tube or 96 orifice plates, and a kind of rifle head of novel applicable Multi-channel liquid transfer device is provided, this liquid transfer gun head can not only solve the not tight problem of rifle head card, and the conventional efficient that can solve spacing difference initiation between rifle head reduces and finally affects the situation of experimental result.
The purpose of this utility model is achieved through the following technical solutions:
A kind of townhouse formula rifle head being applicable to multichannel liquid-transfering gun, comprise multiple rifle head with branch sleeve, wherein: each rifle head is combined into a townhouse formula structure by connector, the upper inner cylinder wall of each rifle head branch sleeve is provided with multiple tracks (3-7 road) ring wall formula protruding.
In the utility model, the height of projection 0.15mm of described annular projection; Connector between each rifle head and between rifle head in integral structure, plastic material can be utilized once injection molded, and its cross section can be carefully cylindric or sheet.
The utility model has the advantage of: simple and practical, solve suction that rifle head plug-in mounting tightly do not cause and do not go up liquid or can not the defect of accurate imbitition, and the conventional efficient caused due to spacing difference between rifle head in prior art can be avoided to reduce, finally affect the phenomenon of experimental result.
Accompanying drawing explanation

The structure top view of the independent rifle head of Fig. 2;
In figure: 1 is rifle head, 2 is branch sleeve, and 3 is protruding, and 4 is connector, and 5 is pipettor.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As depicted in figs. 1 and 2, a kind of townhouse formula rifle head being applicable to multichannel liquid-transfering gun, comprise multiple rifle head 1 with branch sleeve 2, wherein: each rifle head 1 is combined into a townhouse formula structure by connector 4, the upper inner cylinder wall of each rifle head branch sleeve is provided with 3-7 road ring wall formula projection 3.
Design principle of the present utility model is: the fixed connecting piece between rifle head can allow between rifle head and keep equidistant, and rifle head inwall annulus projection plays the effect of increasing friction force, and rifle head and liquid-transfering gun can be made to combine closely.In use, hand-held Multi-channel liquid transfer device, correspondence puts into Novel gun head, easy to use.Therefore the rifle head of this novel multi-channel liquid-transfering gun effectively can solve in one group of rifle head and have one or several rifle head to insert tight and spacing not wait the conventional efficient caused to reduce the also final situation affecting experimental result.
The above; for better case study on implementation of the present utility model; not to any restriction of the present utility model, every make with the utility model technical spirit any amendment, change and equivalence structure change, all belong to the protection category of technical solutions of the utility model.
