Abstract
The utility model discloses a novel suction pipette, including an imbibition section of thick bamboo and injection gun head, the inside piston push rod that is equipped with in imbibition section of thick bamboo upper end, imbibition section of thick bamboo lower extreme and three way connection chamber upper end intercommunication, three way connection chamber right -hand member and feed liquor pipe intercommunication, three way connection chamber right -hand member is equipped with the feed liquor valve, three way connection chamber left end passes through fluid -discharge tube and injection gun head intercommunication, and three way connection chamber left end is equipped with the flowing back valve, the overhead face of injection gun is equipped with the handle of the removal of being convenient for, is equipped with a plurality of injection mouths below the injection gun head. Imbibition section of thick bamboo upside is equipped with the stop hook. The overhead visor that is used for lid protection injection mouth below the injection gun head that is equipped with of injection gun. The reaction liquid that the device can once accomplish all reaction tubes adds to avoid appear to leak adding or the condition of repeated interpolation, and the measurement of the reaction liquid of the interpolation in each reaction tube equals the deviation can not appear.
Description
Technical field
The utility model is specifically related to a kind of novel pipettor.
Background technology
In modern molecular biology research field, it is necessary to carry out various molecular cloning and pcr amplification operation. In these operations, all to be used pipettor. Existing pipettor once can only add the reaction solution of certain volume in a reaction tubes, and when carrying out pcr amplification reaction for use porous PCR Sptting plate, efficiency of its interpolation reaction solution is lower, also easily occurs that leakage adds or repeats the situation of interpolation.
Practical novel content
The purpose of this utility model is to overcome the shortcoming of prior art, it is provided that a kind of novel pipettor, to solve existing pipettor when adding reaction solution in reaction tubes, it is easy to occur leaking the problem adding or repeating to add.
For achieving the above object, technical solution adopted in the utility model is: provide a kind of novel pipettor, comprise imbibition cylinder and filling gun head, inside, imbibition cylinder upper end is provided with piston push rod, the lower end of imbibition cylinder is connected with three-dimensional connection chamber upper end, three-dimensional connection chamber right-hand member is connected with liquid-inlet pipe, and three-dimensional connection chamber right-hand member is provided with liquid feed valve; Three-dimensional connection chamber left end is connected with filling gun head by liquid discharge pipe, and three-dimensional connection chamber left end is provided with tapping valve; It is provided with the handle being convenient to movement above filling gun head, below filling gun head, it is provided with some injection nozzle.
As preferably, being provided with gear hook on the upside of imbibition cylinder.
As preferably, filling gun head is provided with the protective cover protecting injection nozzle below filling gun head for covering.
The beneficial effects of the utility model are:
1, after the utility model sucks enough reaction solutions in imbibition cylinder, make the air emptying in filling gun head and all injection nozzle, mobile filling gun head makes each injection nozzle corresponding separately with a reaction tubes, promotes piston push rod to make each injection nozzle inject appropriate reaction solution in the reaction tubes of correspondence downwards. The reaction solution that this device can once complete all reaction tubess adds, thus avoids occurring that leakage adds or repeats situation about adding, and the metering of the reaction solution of interpolation in each reaction tubes is equal there will not be deviation.
2, it is provided with gear hook on the upside of the utility model imbibition cylinder, catches on when gear is hooked in downward promotion piston push rod convenient with a finger.
3, the utility model filling gun head is provided with the protective cover protecting injection nozzle below filling gun head for covering, and is covered below filling gun head by protective cover when not using, it is possible to avoid injection nozzle to be bruised.
Accompanying drawing explanation
Fig. 1 is the structure iron of novel pipettor.
Wherein: 1, piston push rod; 2, hook is kept off; 3, imbibition cylinder; 4, liquid feed valve; 5, three-dimensional connection chamber; 6, tapping valve; 7, liquid discharge pipe; 8, injection nozzle; 9, protective cover; 10, filling gun head; 11, handle; 12, liquid-inlet pipe.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.
With reference to figure 1, the present embodiment provides a kind of novel pipettor, and inside, imbibition cylinder 3 upper end is provided with piston push rod 1, and imbibition cylinder 3 times ends are connected with three-dimensional connection chamber 5 upper end, and three-dimensional connection chamber 5 right-hand member is connected with liquid-inlet pipe 12, and three-dimensional connection chamber 5 right-hand member is provided with liquid feed valve 4. Three-dimensional connection chamber 5 left end is connected with filling gun head 10 by liquid discharge pipe 7, and three-dimensional connection chamber 5 left end is provided with tapping valve 6. Filling gun head 10 is provided with the handle 11 being convenient to movement above, and filling gun head 10 is provided with some injection nozzle 8 below. Gear hook 2 it is provided with on the upside of imbibition cylinder 3. Filling gun head 10 is provided with the protective cover 9 protecting injection nozzle 8 below filling gun head 10 for covering.
In implementation process, liquid-inlet pipe 12 connects the reagent bottle that reaction solution is housed, and is opened by liquid feed valve 4 and is closed by tapping valve 6, upwards draws high piston push rod 1 and sucked in imbibition cylinder 3 by reaction solution. After imbibition cylinder 3 sucks enough reaction solutions, close liquid feed valve 4, open tapping valve 6 and take off protective cover 9. Promote piston push rod 1 that reaction solution is filled into into filling gun head 10 downwards, make the air emptying in filling gun head 10 and all injection nozzle 8. Catching handle 11 to move filling gun head 10 with hand makes each injection nozzle 8 corresponding separately with a reaction tubes, promotes piston push rod 1 to make each injection nozzle 8 inject appropriate reaction solution in the reaction tubes of correspondence downwards. The reaction solution once completing all reaction tubess adds, thus avoids occurring that leakage adds or repeats situation about adding, and the metering of the reaction solution of interpolation in each reaction tubes is equal there will not be deviation.
Above-mentioned enforcement mode is used for explaining explanation the utility model; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment made by the utility model and change, all fall into protection domain of the present utility model.
