Abstract
The utility model provides a DNA agaropectin cutting means, it includes that upper and lower end establishes as uncovered, as to establish the cavity in it barrel its characterized in that, and this cylinder bottom periphery is established to the blade. Can conveniently pass through the barrel of end band blade down, make researcher when cutting DNA agaropectin, only need press the barrel, the quire just can downcut the agaropectin that meets the requirements together. Not only improved cutting efficiency, can also avoid because of cut the pollution that causes many times. Simultaneously, use this instrument once only to cut, can also avoid cutting off the DNA passage, guaranteed its integrality.
Description
Technical field
The utility model relates to a kind of cutting tool, particularly a kind of DNA agaropectin cutting tool, belongs to experiment apparatus design and manufacturing technology field.
Background technology
In the separation and purification experiment of DNA fragmentation, normally the agaropectin containing DNA sample is carried out electrophoretic procedures, then determined the position of required DNA fragmentation by gel camera work, then operation is cut to the agaropectin containing target DNA fragments.Traditional glue mode of cutting needs each partial application of the surrounding of target agaropectin, removes unnecessary agar blob of viscose and namely obtains required DNA fragmentation.Cut glue technology due to tradition often to obtain a DNA fragmentation and need to cut glue four times, not only loaded down with trivial details but also easily introduce contaminating impurity, also there is the risk destroying DNA fragmentation.Therefore be necessary to be improved prior art.
Summary of the invention
For solving existing DNA agaropectin when obtaining DNA fragmentation, need to cut agaropectin surrounding, owing to all needing to cut four blade, cause cutting efficiency lower and easily cause the problem of pollution, the utility model provides a kind of DNA agaropectin cutting tool at every turn.
The utility model is completed by following technical proposal: a kind of DNA agaropectin cutting tool, it is characterized in that it comprises upper and lower end and is set to uncovered, to establish cavity in it cylindrical shell, this cylindrical shell lower end peripheral is set to cutting edge, DNA agaropectin is cut into required form by the cutting edge of this cylindrical shell lower end peripheral is disposable.
The cross section of described cylindrical shell is set to circle, ellipse or polygon, and the cavity in it is communicated with the uncovered of upper and lower end, so that the agaropectin cut out is satisfactory circle, ellipse or polygon.
Described cylindrical shell is provided with handle, to grasp handle carrying out cutting operation.
The utility model has following advantages and effect: adopt such scheme, can, conveniently by the cylindrical shell of lower end band cutting edge, make researcher when cutting DNA agaropectin, only need by lower shell, and one block of satisfactory agaropectin just can cut by a cutter.Not only increasing cutting efficiency, can also avoiding because repeatedly cutting the pollution caused.Meanwhile, use the disposable cutting of this instrument, DNA fragmentation can also be avoided to cut off, ensure that its integrality.Be a desirable cutting tool in fact.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model;
Fig. 2 is the top view of the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
The DNA agaropectin cutting tool that the utility model provides, comprise upper and lower end and be set to uncovered, to establish cavity 3 in it cylindrical shell 1, this cylindrical shell 1 lower end peripheral is set to cutting edge 4, the cross section of described cylindrical shell 1 is set to rectangle, cavity 3 in it is communicated with the uncovered of upper and lower end, so that the agaropectin cut out is satisfactory rectangle; Described cylindrical shell 1 is provided with handle 2, to grasp this handle 2 carrying out cutting operation.By the cutting edge 4 of this cylindrical shell 1 lower end peripheral is disposable, DNA agaropectin is cut into required form.
