Abstract
The invention discloses an air-leakage prevention pipe body. The air-leakage prevention pipe body comprises a main 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 1mm-2mm larger than the outer diameter of a fixed part at the front end of a rubber pipette bulb; in usage of the pipe body, 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 air-leakage prevention pipe body, 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 easy to joint, and inconvenience caused by air leakage in experiments is prevented. The air-leakage prevention pipe body is used in a laboratory.
Description
Technical field
The present invention relates to a kind of anti-gas-leak body.
Background technology
Carry out chemical classes experiment in laboratory and time often can use pipette (pipette) to measure a certain amount of liquid, in operating process, rubber pipette bulb front end should insert or immediately suitable for reading at pipette (pipette), and notes sealing.And the front end due to rubber pipette bulb is larger than pipette (pipette) back cut diameter in practical operation, usually cannot the scale of appointment will maybe cannot be reached in solution suction line due to gas leakage.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 error effect experimental result.
Summary of the invention
The present invention is directed to 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 due to rubber pipette bulb existing in prior art, usually cannot will in solution suction line, maybe cannot reach the shortcoming of assigned scale due to gas leakage.The technological means that the present invention adopts is as follows:
A kind of anti-gas-leak body, comprising: body main body and body front end; Characterized by further comprising: body tail end, described body tail end caliber is than the wide 1～2mm of rubber pipette bulb front end fixed part external diameter, and when use, described rubber pipette bulb front end fixed part inserts in 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 as preferred described body main body the graduation mark that can measure.
Compared with the prior art, the present invention has the following advantages:
1, moving rubber pipette bulb in liquid, quantity of fluid process can engage with body tail end, and air-tightness is better.
2, simple in structure, easy to use.
The present invention has can realize suitability for industrialized production, modern design, simple in structure and have the very advantage such as high performance-price ratio, and it puts goods on the market and will produce Social benefit and economic benefit significantly.
Accompanying drawing explanation
Fig. 1 is invention structural representation.
Fig. 2 is inventive embodiments 1 structural representation.
Fig. 3 is inventive embodiments 2 structural representations.
The specific embodiment
As shown in Figure 1, a kind of anti-gas-leak body, comprising: 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 when use, described rubber pipette bulb front end fixed part inserts in body tail end 3, owing to being interference fit, so rubber pipette bulb can be realized sealing completely 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.Moving rubber pipette bulb in liquid, quantity of fluid process can engage with body tail end 3, and air-tightness is better, simple in structure, easy to use.
Embodiment 1, 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, when use, described rubber pipette bulb front end fixed part inserts in body tail end 3, owing to being interference fit, so rubber pipette bulb can be realized sealing completely with body tail end 3.Concrete operations are, take 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 ball, 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 slow solution inspiration pipe, 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 to required container in addition, body front end 2 gos deep in vessel port, unclamps the right hand forefinger solution is flowed down naturally.
Embodiment 2, as shown in Figure 3, 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 graduation mark 5, described body tail end 3 calibers are than the wide 1～2mm of rubber pipette bulb front end fixed part external diameter, when use, described rubber pipette bulb front end fixed part inserts in body tail end 3, owing to being interference fit, so rubber pipette bulb can be realized sealing completely with body tail end 3.Concrete operations are, take 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 ball, 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 slow solution inspiration pipe, until required scale, remove rubber pipette bulb, block pipette body tail end 3 with right hand forefinger rapidly, pipette is transferred to required container in addition, body front end 2 gos deep in vessel port, unclamps the right hand forefinger solution is flowed down naturally.
The above; it is only the preferably specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
