Description
Technical field
The utility model belongs to experiment equipment field, is related to a kind of liquid relief equipment, specifically it is a kind of it is anti-pollution can
Flexible liquid transfer gun head.
Background technology
Liquid-transfering gun is the common instrument in the laboratory in the fields such as chemistry, biology, medical treatment, and liquid-transfering gun is in use
It needs largely to use disposable liquid transfer gun head, for pipetting for laboratory fluids.
Current existing liquid transfer gun head there is a problem of very much：
（1）In existing structure design, the inner wall smooth of liquid transfer gun head, the frictional force between liquid-transfering gun is small, causes
After drawing liquid weeping or liquid transfer gun head may occur for the poor sealing between liquid transfer gun head and liquid-transfering gun from liquid-transfering gun
On the phenomenon that falling off cause the pollution of liquid, cause experimental result poor accuracy or even pipette tips to fall the liquid drawn into needs
In bottle, the contaminated waste of the fluid sample of whole bottle is caused；
（2）Deformation is too fast, and imbibition overexerts during the use of liquid-transfering gun, or because taking liquid process spring to restore
When, it can be by the joining place of draws fluid liquid-transfering gun and liquid transfer gun head, even in liquid-transfering gun, joining place is non-sterile processing
Other liquid have been infected at position, and therefore, liquid can be contaminated, to influence the accuracy of experimental result, and if liquid fall
It is upper to be drawn onto trunk, as trunk moves upwards, liquid further corrodes sealing ring and piston, leads to gas leakage；
Cause the preci-sion and accuracy of liquid-transfering gun to decline, increases the cost of purchase liquid-transfering gun, also there is liquid transfer gun head at present
It prevents from being drawn onto in liquid-transfering gun on liquid, is equipped with liquid buffer area on pipette tips top, but this pipette tips volume increase is not with harvesting；
（3）The length of liquid transfer gun head generally all fixed dimension at present, less for amount of liquid, liquid level is needed than shallower bottle
Go deep into liquid transfer gun head even liquid-transfering gun that could draw liquid in bottle, be easy to cause liquid-transfering gun in this way and be contaminated, especially needle
To narrow-mouthed bottle, liquid-transfering gun can not go deep into bottle, it may be necessary to which being transferred out of liquid could draw, and may turn for such situation
It is polluted during shifting, to influence experimental data, if not being transferred out of, then causes to waste.
Utility model content
The purpose of this utility model is to provide one kind anti-pollution telescopic liquid transfer gun head in view of the deficiencies of the prior art,
It can prevent pipette tips from falling into liquid bottles, pollute whole bottle liquid, when liquid level is relatively low in bottle, convenient for drawing liquid；When firmly
Prevent liquid from polluting liquid-transfering gun when too quickly, while easy to use, convenient for harvesting.
To achieve the above object, the utility model provides the following technical solutions：
A kind of anti-pollution telescopic liquid transfer gun head, including pipette tips main body and sealing ring, sealing ring are arranged in pipette tips main body
Linkage section inside, be interference fitted with the lower end of liquid-transfering gun；
It is equipped with two opposite strips outside the linkage section of pipette tips main body, the strip extends outwardly protrusion；
The linkage section of pipette tips main body is connected with fluid suction head by liquid buffer area, and the fluid suction head middle section is that can roll over
Folded stretching structure, the liquid buffer area are the cylinder of folding stretching structure.
Further, the material of the sealing ring is elastic rubber.
Further, the interior lower end of the linkage section is equipped with taper flow-stopping plate.
Further, the pipette tips main body is plastic material.
Further, the liquid buffer area box fluid suction head middle section is folding telescopic plastic material structure
At.
The utility model has the beneficial effects that：
Strip is equipped in the utility model outside the linkage section of pipette tips main body, prevents pipette tips main body from falling into liquid bottles
In, whole bottle liquid is polluted, the linkage section of pipette tips main body is internally provided with elastic seal ring, more efficient to prevent pipette tips from falling off and leaking
Gas prevents the quantity for drawing liquid from error occur；When imbibition is excessive or too fast, the liquid for having more or being sucked out can enter excessive liquid
In storage chamber, liquid-transfering gun toggle will not be polluted；Increase the spatial volume of buffer area, and facilitate storage, is not take up space, buffer area
The taper flow-stopping plate on top, can be to effectively being stopped, together because of the drop etc. that misoperation such as imbibition is too fast, picks up or splashes
When being also prevented from liquid-transfering gun and accidentally keeping flat, prevent from liquid contact liquid-transfering gun toggle or enter in liquid-transfering gun to pollute；Imbibition
The middle part of head is foldable shape, can be adjusted according to the depth of liquid side in bottle, for the fewer reagent bottle of liquid, into
Row is drawn, and waste is reduced, and reduces pollution, and the utility model is simple in structure, of low cost, easy to use, convenient for harvesting.
