Abstract
A kind of arc pipettor gun head, belongs to pipettor gun head technical field.Rifle head is that hollow is conical, and the axial line of circular cone is arc.Rifle head is arc, accurately can pipette the liquid in bottle, when being particularly useful for there is a small amount of liquid in bottle.With during straight-tapered rifle head imbitition because amount of liquid is few, bottleneck angle etc. makes liquid assimilating inconvenient, inaccurate, in rifle head, liquid easily has air to be mixed into, the accuracy of impact experiment; And easily have more liquid residue, pollute the waste with reagent.Adopt arc rifle head can accurate imbitition, reduce liquid residue, avoid waste, reduce cost, the inaccuracy that caused by bottle pouring liquid and reagent can be avoided again to remain the pollution caused, ensure the accuracy of testing.
Description
Technical field
The utility model relates to a kind of arc pipettor gun head, belongs to pipettor gun head technical field.
Background technology
In the liquid state or semi liquid state sample extraction process of biochemical test, medical test, often can use pipettor, pipettor is furnished with the rifle head of different size.But the pipettor gun head of routine is straight-tapered, often having the liquid in bottle to get in an experiment does not totally have residual polluting to affect experiment effect or reagent waste.If directly in dumping bottle, liquid can cause that to get liquid measure inaccurate, or reagent contamination.
Utility model content
The utility model is intended to solve above-mentioned problems of the prior art, proposes a kind of arc pipettor gun head.
Described pipettor gun head and pipettor with the use of.
A kind of arc pipettor gun head, as shown in Figure 1, is characterized in that, described rifle head is that hollow is conical, and the axial line of circular cone is arc; The large mouth of rifle head hollow circular cone is installing port, and comparatively osculum is liquid inlet and outlet.The comparatively osculum of described rifle head hollow circular cone is oval, liquid inlet and outlet and datum line k in same level, with the line of the liquid inlet and outlet of rifle head and installing port for datum line k.
As shown in Figure 2, the maximum deflection angle α of described rifle head is 10 ° ~ 30 °.Described knuckle is: the tangent line m making camber line with the some A that knuckle on the outer camber line of rifle head sidewall is maximum, the angle of datum line k and tangent line m two lines is maximum deflection angle α.Do vertical line from an A to datum line k, intersect at B point with datum line k.Distance d between A, B be rifle head by the minimum diameter of bottleneck.
The cone angle of described hollow circular cone is 20 ° ~ 25 °.
Beneficial effect:
Arc pipettor gun head of the present utility model, rifle head is that arc is cone shape, accurately can pipette the liquid in bottle, when being particularly useful for there is a small amount of liquid in bottle, time inconvenient with straight-tapered rifle head imbitition.The present invention adopt arc rifle head effectively prevent with during straight-tapered rifle head imbitition because amount of liquid is few, bottleneck angle etc. makes liquid assimilating inconvenient, inaccurate, easily have air to be mixed into the shortcoming with liquid residue.Can accurate imbitition, avoid the inaccuracy of bottle being toppled over imbibition; Waste can be avoided again, economize on resources, reduce cost, reduce the risk of reagent contamination, ensure the accuracy of experiment.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this arc pipettor gun head;
Fig. 2 is this arc pipettor gun head arc angles schematic diagram;
Fig. 3 uses this arc pipettor gun head to draw liquid schematic diagram in bottle;
1 arc pipettor gun head, 2 bottles, fluid level in 3 bottles.
Detailed description of the invention
Below in conjunction with specific embodiment and accompanying drawing, the use to this arc pipettor gun head is explained, but is not limited to following examples.
Fig. 1 is shown in by the schematic diagram of arc pipettor gun head, and Fig. 2 is shown in by arc pipettor gun head arc angles schematic diagram, and arc pipettor gun head is drawn liquid schematic diagram in bottle and seen Fig. 3.
First, this arc pipettor gun head is connected with pipettor.Tilt to make liquid concentrate on neck part by bottle, stretch into this arc pipettor gun head, the liquid inlet and outlet of lower end extends liquid level once, draws liquid in bottle, carries out subsequent experimental.
This arc pipettor gun head is used in imbitition, can draw the amount of liquid of needs during a small amount of liquid especially in narrow-mouthed bottle accurately, avoids moving the inaccurate of liquid measure and waste reagent.It also avoid the pollution that liquid residue causes.Improve the efficiency of experiment, improve the accuracy of experiment, reduce the cost of experiment, reduce consumptive material, avoid waste.
