Abstract
The utility model discloses a rubber pipette bulb. The rubber pipette bulb is designed targeted at the complexity, time consuming and operation difficulties that the liquid relief process needs to be finished by two hands when a traditional rubber pipette bulb is used, simultaneously, the air leakage easily happens in the operation process to cause midway failure of the liquid relief process, the liquid volume also needs to be regulated after the liquid relief, and the like. A quantifying ball is additionally arranged inside the traditional rubber pipette bulb, a suction port of the traditional rubber pipette bulb is expanded, furthermore, the connection mode between the traditional rubber pipette bulb and a liquid relief pipe is adjusted to a sleeving mode from the original insertion mode, and therefore, the liquid relief process can be rapidly, quantitatively, and accurately finished once by using a single hand.
Description
Technical field
The utility model relate to a kind of can be quantitative, capacity is the rubber pipette bulb of 5ml, 10ml, 15ml, 20ml or 25ml.
Background technology
The pipetting of the inside, laboratory, mainly be to pipette liquid by the auxiliary pipette of rubber pipette bulb, detailed directions is exactly that a handgrip pipette inserts in the liquid, the top of pipette is inserted in one handgrip ear washing bulb lower end, and the extruding ear washing bulb is drawn onto liquid in the pipette, remove rubber pipette bulb, block above the pipette with finger simultaneously rapidly, the liquid volume in the pipette is adjusted to volume required, again liquid is wherein put into the vessel that will put into.Whole operation wants both hands to use simultaneously, and because rubber pipette bulb belongs to shallow with the pipette junction and contacts, operate frequent the causing because of gas leakage of unskilled person and move the liquid failure midway, and also to carry out the volume adjustment after moving liquid, and also can cause because of gas leakage in the transfer process after moving liquid and move the liquid failure, so move the more loaded down with trivial details time-consuming and operating difficulties of liquid process.
Summary of the invention
Use traditional rubber pipette bulb to move loaded down with trivial details time-consuming, the operating difficulties of liquid for overcoming, the utility model provides a kind of rubber pipette bulb in the past.
The utility model mainly adopts following technical scheme: a kind of rubber pipette bulb comprises compressed ball (1), quantitative ball (2), quantitative ball pore (3), connector (4), it is characterized in that: quantitatively ball (2) is nested in the compressed ball (1), and closely link to each other at connector (4), have quantitative ball pore (3) at quantitative ball (2), rubber pipette bulb is connected with pipette after being inserted in the pipette upper end by connector (4), the suction pipe lower end is inserted in the solution, press rubber pipette bulb compressed ball (1) to quantitative ball (2) with hand, unclamp compressed ball (1), solution sucks in the suction pipe, the suction pipe lower end is put into the container that needs immigration, press rubber pipette bulb compressed ball (1) to quantitative ball (2) with hand, namely finish pipetting.
A kind of rubber pipette bulb capacity of the utility model can be any one of five kinds of 5ml, 10ml, 15ml, 20ml or 25ml.
When a kind of rubber pipette bulb capacity of the utility model was 5ml, the volume of the disposable imbitition of rubber pipette bulb was 4.6ml to 5.4ml.
When a kind of rubber pipette bulb capacity of the utility model was 10ml, the volume of the disposable imbitition of rubber pipette bulb was 9.2ml to 10.8ml.
When a kind of rubber pipette bulb capacity of the utility model was 15ml, the volume of the disposable imbitition of rubber pipette bulb was 13.6ml to 16.4ml.
When a kind of rubber pipette bulb capacity of the utility model was 20ml, the volume of the disposable imbitition of rubber pipette bulb was 18.2ml to 21.8ml.
When a kind of rubber pipette bulb capacity of the utility model was 25ml, the volume of the disposable imbitition of rubber pipette bulb was 22.6ml to 27.4ml.
A kind of rubber pipette bulb of the utility model and traditional rubber pipette bulb relatively have significant advantage, and a kind of rubber pipette bulb one hand can be finished quantitative pipetting, have avoided in the operation both hands to operate simultaneously, move liquid and have leaked gas, move behind the liquid the more loaded down with trivial details operations such as quantitative midway.
Description of drawings:
Fig. 1 is the elevational schematic view of a kind of rubber pipette bulb of the utility model, comprising:
Compressed ball (1), quantitative ball (2), quantitative ball pore (3), connector (4).
