Accompanying drawing explanation
Fig. 1 is the structural representation of multi-channel loading device of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the present invention will be described, for embodiment be only make generality to product of the present invention or method to illustrate, contribute to understanding the present invention better, but can't the scope of the invention be limited.Experimental technique described in following embodiment, if no special instructions, is conventional method; Described material, if no special instructions, all can obtain from commercial channels.
Refer to Fig. 1, a kind of multichannel liquid sample injector of the present invention, the sample adding device that its agent structure comprises passive support body, is arranged on the lifting platform 2 on described support body and is arranged on described lifting platform 2, described sample adding device realizes liquid application of sample by lifting platform 2 moving up and down on described support body, sample adding device is in diverse location when terminating the different conditions such as application of sample.
Wherein, described support body comprises base plate 11 and symmetrical a pair support column 12 be arranged on described base plate 11, described in a pair, support column 12 is each passed through the hole that lifting platform 2 is offered, described lifting platform 2 is moved up and down along support column 12, and be fixed on described support column 12 by the lifting locking knob 21 be arranged on described lifting platform 2, the present invention preferably, described support body also comprises one piece and the vertically disposed backboard 13 of base plate 11, with be arranged on described backboard 13 upper end, the fixed head 14 playing fixation of described support column 12 upper end, particularly, fixed head 14 is the U-type strip plate of aluminum alloy material, the distance that support column described in a pair 12 points is clipped to described backboard 13 is equal, therefore, the integrative-structure of this U-type strip plate can reinforce the rectangular frame be connected to form by support column 12 upper end and backboard 13 upper end, make the whole frame structure of the present invention firm further, not easily rock.
As shown in Figure 1, sample adding device described in the present invention comprises funnel-form reservoir 31 is communicated with reservoir 31 closing in end inverted T shape apocenosis passage 41 with top, tapping switch 32 is provided with on described reservoir 31, near its closing in end place, bottom described inverted T shape apocenosis passage 41, be provided with several sample needles 44, often only described sample needle 44 passes described lifting platform 2 and is fixed on lifting platform 2.Particularly, comprise reservoir 31 described at least one, the quantity of reservoir 31 is relevant according to the fluid sample species number used required in application of sample process, in general, the quantity of reservoir 31 is greater than fluid sample species number, because between different liquids sample pipetting volume process, also need the flushing using the reservoir 31 that cleaning fluid is housed to carry out sample needle.
The present invention in use, is rotatably provided in the lifting locking knob 21 on described lifting platform 2, is risen by lifting platform 2 and adjust to correct position, be placed on base plate 11 by the centrifuge tube shelf 5 that centrifuge tube is housed, make the opening part of centrifuge tube aim at sample needle 44 respectively.Then, in the reservoir 31 be fixed on apocenosis passage 41, add the fluid sample being about to carry out application of sample, or be fixed on again on apocenosis passage 41 after first adding fluid sample in reservoir 31.After getting out above-mentioned work, by lifting locking knob 21, lifting platform 2 is slowly moved down, drive the syringe needle of sample needle 44 to drop in each centrifuge tube, locking lifting locking knob 21, the position of now lifting platform 2 is fixed on support column 12.Finally, can slowly open tapping switch 32, the fluid sample in reservoir 31 be flow in each sample needle 44 respectively through inverted T shape apocenosis passage 41, finally makes fluid sample join in centrifuge tube.After application of sample terminates, when needing the application of sample carrying out another fluid sample continuously, only need take out centrifuge tube, reservoir 31 add cleaning fluid, after T-shaped apocenosis passage 41 and sample needle are cleaned up, repeats aforesaid operations.
As shown in Figure 1, sample adding device described in the preferred embodiment of the present invention also can comprise the corresponding separatory passage 42 be arranged between described apocenosis passage 41 and described sample needle 44, and each described separatory passage 42 is provided with separatory switch 43.By this design, better can adapt to the requirement of different experiments, design different sample loading alternative.So, fluid sample multichannel application of sample simultaneously can be realized by multichannel liquid sample injector of the present invention, time saving and energy saving, reduce error and reduce error probability.The present invention is especially applicable to the liquid application of sample of centrifuge tube, by the setting of twice switch, effectively controls liquid application of sample flow velocity, avoids different liquids to add in same pipe and occur mixing phenomenon mutually.Due to described support column 12 be the cylinder of aluminum alloy material or stainless steel, the described reservoir 31 transparent or semitransparent cell body that is PC material, described lifting platform 2 cuboid that is aluminum alloy materials, make the present invention have shatter-resistant antidetonation, light firmly feature.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
