Abstract
The utility model discloses a round-head liquid transfer suction pipe capable of preventing cells from being damaged. The round-head liquid transfer suction pipe comprises a suction pipe body (1), wherein the lower end of the suction pipe body (1) is an arc pipe opening (2) with a hole in the middle. By the round-head liquid transfer suction pipe, the damage rate of the cells is effectively reduced; the round-head liquid transfer suction pipe is integrated, so that liquid can be accurately and quantitatively transferred in a process of sucking and blowing the cells; and the round-head liquid transfer suction pipe has strong-acid resistance and strong-alkaline resistance and can be repeatedly sterilized. The round-head liquid transfer suction pipe can be widely applied to tissue cultivation, cell cultivation, bacteriology research and clinical research.
Description
Technical field
The utility model relates to cytobiology, molecular biology experiment research device field, relates in particular to a kind of round end whole pipet that prevents cell injury.
Background technology
In cytobiology, molecular biology experiment research, the quantitative transfer of cell and virus transfection, the undamaged quantitative mixing of different sources cell solution are the most basic experimental implementation.Devices such as liquid-transfering gun head, common whole pipet are used in the laboratory mostly, and cell is drawn.Common in the market whole pipet is divided into 1mL, 2mL, and regular sizes such as 5mL and 10mL mostly are glass or polypropylene material, but the following problem of ubiquity:
Though but the 1. suction pipe high temperature high voltage resistant of polypropylene material, acid-fast alkali-proof can not use repeatedly, the use cost height.
2. existing whole pipet, no matter be glass material or the polypropylene material, its bottom mouth of pipe is line style, the mouth of pipe is unsmooth, sharp-pointed (seeing Fig. 1-3); When using it to carry out histiocytic quantitative transfer, the cell injury rate reaches 15% approximately, and in different solutions mixing process, the cell injury rate is then up to 20%; Particularly in the virus transfection experiment, the cell injury rate is higher, has influenced experimental result greatly.
3. existing part whole pipet is made up of two portions, by sleeve pipe or be welded, quantitative transfer is impacted.
The utility model content
Weak point at existing whole pipet, particularly in moving the liquid process, histocyte is caused the problem of damage, the utility model aims to provide a kind of round end whole pipet, and this round end whole pipet can make cell exempt to damage, range is accurate, the use of also can sterilizing repeatedly.
For achieving the above object, the technical solution of the utility model is:
A kind of round end whole pipet comprises the suction pipe body, and the lower end of suction pipe body is the arc mouth of pipe of intermediate openings.
Described suction pipe body is preferably the suction pipe body of glass.
Described suction pipe body and the arc mouth of pipe are preferably one-body molded.
Below the utility model is made further explanation
Round end whole pipet specification described in the utility model be from 1-50mL any one, can cooperate any a electronic pipettor to use.
The whole pipet of the prior art bottom mouth of pipe is line style, and the mouth of pipe is unsmooth, and is more sharp-pointed, and when quantitatively shifting, the cell injury rate is big; The round end whole pipet mouth of pipe described in the utility model is circular-arc, well solved this technical problem, make and in sampling process, reduce cells injury, use this novel round end whole pipet when manipulating cells solution, the cells injury rate is dropped to below 2%.
Compared with prior art, the beneficial effects of the utility model are:
1, the mouth of pipe is circular-arc bottom the round end whole pipet of the present utility model, and it is smooth and easy to flow when guaranteeing cell solution turnover whole pipet, reduces and collides, and reduces degree of injury, and the cells injury rate is down to below 2%.
3, round end whole pipet cell injury rate of the present utility model is low, simple to operate, and use cost is cheap, can reach good result of use.Particularly in the virus transfection experiment, it is about 10% to find that the round end whole pipet has improved than the transfection efficiency of tip suction pipe, has improved experimental result greatly.
3, round end whole pipet preferred glass material of the present utility model, high temperature high voltage resistant, strong alkali-acid resistance, the use of can sterilizing repeatedly; The one-body molded draw solution that makes is quantitatively accurate; And can cooperate any a electronic pipettor to use.

Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described further.
A kind of round end whole pipet as shown in Figure 4, comprises suction pipe body 1, and the lower end of suction pipe body 1 is the arc mouth of pipe 2 of middle perforate.Described suction pipe body 1 is glass material, and suction pipe body 1 is one-body molded with the arc mouth of pipe 2.
Above-described embodiment only is in order to set forth a kind of embodiment that principle of work of the present utility model provides, to be not restricted to the data of mark in embodiment and the accompanying drawing.Every based on the utility model, its technical characterictic is simply replaced or reconfigured, and do not break away from the technical scheme of the utility model flesh and blood, all should belong within the scope that the utility model protects.
Claims (3)
1. a round end whole pipet comprises suction pipe body (1), it is characterized in that, the lower end of suction pipe body (1) is the arc mouth of pipe (2) of middle perforate.
2. according to the described round end whole pipet of claim 1, it is characterized in that described suction pipe body (1) is the suction pipe body (1) of glass.
