Abstract
The utility model discloses an air-leakage prevention pipe body, which comprises a main body of the pipe body and a front end of the pipe body. The air-leakage prevention pipe body is characterized by further comprising a tail end of the pipe body, wherein the diameter of the tail end of the pipe body is 1-2mm larger than the outer diameter of a fixed part at the front end of a rubber pipette bulb; and during usage, the fixed part at the front end of the rubber pipette bulb is inserted into the tail end of the pipe body. According to the utility model, the tail end of the pipe body is improved, so that when a liquid is measured or transferred, the rubber pipette bulb and the pipe body are easier to joint, and inconvenience caused by air leakage in experiments is prevented. The air-leakage prevention pipe body is a pipe body used in a laboratory.
Description
Technical field
The utility model relates to a kind of anti-gas-leak body.
Background technology
Carry out the chemical classes experiment in the laboratory and the time often can use pipette (pipette) to measure a certain amount of liquid, the rubber pipette bulb front end should insert or be right after at pipette (pipette) suitable for reading in the operating process, and notes sealing.And the front end owing to rubber pipette bulb is larger than pipette (pipette) back cut diameter in practical operation, usually can't will maybe can't reach the scale of appointment in the solution suction line owing to leak gas.Therefore often to carry out repeatedly could drawing a certain amount of solution.Do like this time and effort consuming, also easily because repeatedly cause the error effect experimental result.
Summary of the invention
The utility model is for the proposition of above problem, and a kind of anti-gas-leak body of research and design, larger than pipette (pipette) back cut diameter in order to solve the front end owing to rubber pipette bulb that exists in the prior art, usually can't will maybe can't reach the shortcoming of assigned scale in the solution suction line owing to leak gas.The technological means that the utility model adopts is as follows:
A kind of anti-gas-leak body comprises: body main body and body front end; Characterized by further comprising: body tail end, described body tail end caliber are than the wide 1～2mm of rubber pipette bulb front end fixed part external diameter, and during use, described rubber pipette bulb front end fixed part inserts in the body tail end.
Be provided with the liquid storing part that can carry out liquid storage as preferred described body main body.
Be provided with the graduation mark that to measure as preferred described body main body.
Compared with the prior art, the utlity model has following advantage:
1, move that rubber pipette bulb can engage with the body tail end in liquid, the quantity of fluid process, air-tightness is better.
2, simple in structure, easy to use.
The utlity model has and can realize suitability for industrialized production, modern design, simple in structure and have the very advantage such as high performance-price ratio, it puts goods on the market and will produce significantly Social benefit and economic benefit.

Fig. 2 is the utility model embodiment 1 structural representation.
Fig. 3 is the utility model embodiment 2 structural representations.
The specific embodiment
As shown in Figure 1, a kind of anti-gas-leak body comprises: body main body 1 and body front end 2; Characterized by further comprising: body tail end 3, described body tail end 3 calibers are than the wide 1～2mm of rubber pipette bulb front end fixed part external diameter, and during use, described rubber pipette bulb front end fixed part inserts in the body tail end 3, owing to be interference fit, so rubber pipette bulb can be realized sealing fully with body tail end 3.Described body main body 1 is provided with the liquid storing part 4 that can carry out liquid storage.Described body main body 1 is provided with the graduation mark 5 that can measure.Move that rubber pipette bulb can engage with body tail end 3 in liquid, the quantity of fluid process, air-tightness is better, and is simple in structure, easy to use.
Embodiment 1, and as shown in Figure 2, described a kind of anti-gas-leak body is a kind of pipette, comprising: body main body 1 and body front end 2; Characterized by further comprising: body tail end 3 and liquid storing part 4, described body tail end 3 calibers are than the wide 1～2mm of rubber pipette bulb front end fixed part external diameter, during use, described rubber pipette bulb front end fixed part inserts in the body tail end 3, owing to be interference fit, so rubber pipette bulb can be realized sealing fully with body tail end 3.Concrete operations are, take the pipette upper end with the right hand, and forefinger is suitable for reading near pipe, middle finger, and nameless and thumb is held pipette; Left hand is taken rubber pipette bulb, and rubber pipette bulb is held in the palm, and front end is downward, by tight rubber pipette bulb, discharges air in the ball, the rubber pipette bulb front end is inserted in the pipe of overstriking of pipette body tail end 3, and jam-pack, attention can not be leaked gas.The left-hand finger of coming up, in the slow inspiration pipe of solution, be stored in liquid storing part 4, until required capacity, remove rubber pipette bulb, block pipette body tail end 3 with right hand forefinger rapidly, pipette is transferred in addition required container, body front end 2 gos deep in the vessel port, unclamps the right hand forefinger solution is flowed down naturally.
The above; it only is the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and inventive concept thereof, all should be encompassed within the protection domain of the present utility model.
