Abstract
The utility model discloses a DNA grinding rod, including grinding rod and the handle of connection in grinding rod one end, grinding rod one end be provided with the grinding head, the other end is provided with the hexagonal head, is provided with the hexagonal hole that closely cooperates with the hexagonal head on the handle. The utility model discloses install a detachable handle additional in grinding rod one end, like this alright is holding the handle and is grinding, it is more convenient to use, and can not hinder hand, labour saving and time saving. And after the use completion, can dismantle the handle and get off to be used for experiment next time to continue the use, reach reuse's purpose.
Description
Technical field
The utility model relates to a kind of DNA grinding rod, belongs to laboratory tool technical field.
Background technology
When adopting CTAB method to extract mycelia DNA, need to use DNA grinding rod to grind mycelia.In process of lapping, grinding rod uses with separate grind rod barred body usually, and because barred body top is cylindrical, small volume, material is comparatively hard, and it is hand-held to be in use not only not easy to operating personnel, but also difficulty is to the control of grinding dynamics.When the amount of required grinding mycelia is large, because milling time is long, need again ceaselessly spin finishing excellent to carry out milled processed to mycelia in grinding, this will cause injury to a certain degree to the hand of operating personnel, thus extracting in the experimentation of DNA by CTAB method, grinding mycelia is the most consuming time, a process of effort.In sum, extract there is drawback with when independently DNA grinding rod grinds mycelia in DNA by CTAB method in laboratory, for present circumstances, laboratory needs to improve a kind of Novel DNA grinding rod and solves the problems referred to above.
Summary of the invention
The DNA grinding rod that the utility model provides a kind of structure simple, easy to use, time saving and energy saving, to overcome the deficiencies in the prior art.
The technical solution of the utility model: a kind of DNA grinding rod, comprise grinding rod and the handle being connected to grinding rod one end, described grinding rod one end is provided with grinding head, and the other end is provided with six square toes, handle is provided with and the close-fitting hexagonal hole of six square toes.
Described grinding head is conical structure.
The length of six described square toes is 2 ~ 3cm.
Owing to adopting technique scheme, the utility model has the advantage of: the utility model installs a detachable handle additional in grinding rod one end, so just can hold handle and grind, use more convenient, and can not hand be hindered, time saving and energy saving.And after being used to complete, handle release can being got off for experiment continuation use next time, reach the object of recycling.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of grinding rod in the utility model;
Fig. 3 is the structural representation of handle in the utility model.
Description of reference numerals: 1-grinding rod, 2-handle, 3-grinding head, 4-six square toes, 5-hexagonal hole.
Detailed description of the invention
In order to make the utility model object, technical scheme and advantage clearly, below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment of the present utility model: the structural representation of DNA grinding rod as shown in Figure 1, comprise grinding rod 1 and the handle 2 being connected to grinding rod 1 one end, the barred body of grinding rod 1 adopts PE material to make, its high transparency, good heat resistance, price is lower, can repeatedly sterilizing use; See Fig. 2, grinding rod 1 one end is provided with grinding head 3, described grinding head 3 is conical structure; The other end of grinding rod 1 is provided with six square toes 4, and its length is 2cm.See Fig. 3, handle 2 is provided with and the close-fitting hexagonal hole 5 of six square toes 4, its degree of depth is 2.5cm.During use, six square toes 4 on grinding rod 1 are inserted in the hexagonal hole 5 on handle 2, grinding rod 1 and handle 2 are linked together, namely can be used for grinding.Pulled up from handle 2 by grinding rod 1 after using, after carrying out sterilization treatment, namely can be used for experiment next time and continue to use, handle 2, then without the need to sterilization treatment, only need place, and treats that next time, the experiment taking-up that takes used.
