Abstract
The utility model discloses a loss-free multifunctional automatic quantifying pipette. The loss-free multifunctional automatic quantifying pipette is characterized in that different quantifying balls of different specifications are assembled on the top of the pipette so as to achieve a multifunctional purpose, the quantifying balls and the pipette are combined and sealed, so that liquid leakage is avoided, and the pipette can be used for automatically and quantitatively measuring the liquid in a chemical experiment process. The loss-free multifunctional automatic quantifying pipette comprises a pipette part and the quantifying balls, which can be split and assembled, wherein the pipette part is closely connected with the glue head quantifying balls at the end opening of the pipette, and liquid leakage in a shifting process can be avoided; the standards of the quantifying balls are 1ml, 5ml and 10 ml, the pipette is multifunctional and wide in pipetting range, the quantifying balls are used for carrying out automatic quantifying in extraction and pipetting processes, the operation is simple and rapid, and the experiment efficiency is improved.
Description
technical field:
The utility model relates to a kind of free of losses one tube multipurpose type automatic quantity pipet, is mainly used in pipetting in all kinds of chemical experiments in laboratory the operation of liquid, and it is simple and efficient to handle.
background technology:
In all kinds of chemical experiments, for measuring all of liquid, can use pipette, when using common pipette to pipette liquid, there are following 3 experimental implementation problems: (1), when liquid is in transfer process, we use finger sealing pipette top conventionally, not tight, therefore, during the loosening meeting of finger, liquid is omitted, and waste of material causes experimental cost to improve; (2) when with rubber pipette bulb imbitition, the size of rubber pipette bulb and the top port of pipette do not meet conventionally, repeatedly draw to discharge just can reach and measure target, cause the loaded down with trivial details of operation, elapsed time; (3) in liquid measuring process, often change the pipette of different size, complex operation, increases cost.
utility model content:
In order to solve the existing problem of background technology, the utility model provides a kind of free of losses one tube multipurpose type automatic quantity pipet, technical scheme is as follows: comprise quantitative system, it is characterized in that: quantitative system comprises the quantitative ball of 10ml, the quantitative ball of 5ml and the quantitative ball combined quantitative of 1ml system, quantitative system lower end is provided with is with graduated pipette, the both sides of each quantitative ball are equipped with sealed steel ball, and sealed steel ball is positioned at the arm with quantitative ball, between quantitative system and pipette, by sebific duct, connects.
The quantitative ball of described 10ml, the quantitative ball of 5ml and the quantitative ball of 1ml are fabricated structure.
The beneficial effect that the utility model has is: (1) has solved well liquid and in transfer process, pointed the poorly sealed liquid omission that tightly causes, and has reduced consumption of raw materials; (2) solve the size of rubber pipette bulb and the top port of pipette does not meet, repeatedly drawn to discharge and just can reach the problem that measures target, reduced time loss; (3) solved while measuring different volumes liquid, frequently changed the problem of pipette.The utility model can be used for pipetting in all kinds of experiments in laboratory the operation of fluid sample, and its preparation process is simple, simple in structure, and cost is low.Quantitatively gauge ball lattice are respectively 1ml, and 5ml and 10ml, realize one tube multipurpose, moves liquid wide ranges, rely on quantitative ball automatic ration in shifting out process getting liquid and liquid, simple and efficient to handle, have improved conventional efficient.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is quantitative ball steel ball sealing junction profile.
In figure: the quantitative ball of 1-10ml, the quantitative ball of 2-5ml, the quantitative ball of 3-1ml, 4-sebific duct, 5-pipette, 6-sealed steel ball, 7-arm.
the specific embodiment:
In conjunction with Fig. 1 and Fig. 2, the specific embodiment is by the following technical solutions: comprise quantitative system, it is characterized in that: quantitative system comprises the quantitative ball 1 of 10ml, the quantitative ball 3 combined quantitative systems of the quantitative ball 2 of 5ml and 1ml, quantitative system lower end is provided with is with graduated pipette 5, the both sides of each quantitative ball are equipped with sealed steel ball 6, and sealed steel ball 6 is positioned at the quantitative arm 7 of ball, between quantitative system and pipette 5, by sebific duct 4, connect.The quantitative ball 1 of 10ml, the quantitative ball 3 of the quantitative ball 2 of 5ml and 1ml is fabricated structure.
Concrete operation step of the present utility model is: take and pipette 10ml liquid as example, the first step is pinched out the sealed steel ball 6 use hands in quantitative ball outside in quantitative system, discharges the air in quantitative system simultaneously, unclamps sealed steel ball 6; Second step, is inserted into pipette 5 in liquid to be measured, and the sealed steel ball 6 use hands of quantitative ball inner side in quantitative ball system are pinched out, and liquid sucks in pipette automatically; The 3rd step, aims at vessel port to be discharged by pipette 5, pinches out the sealed steel ball 6 of quantitative ball both sides in fixed system with hand simultaneously, and liquid is discharged in container automatically, pipettes complete.
This pipette can be used in combination the quantitative ball of different size, and the method that other volumes measure liquid is identical with topic example.
