Abstract
The utility model provides a kind of novel flat-plate magnetic force spreader, it includes magnetic force spreading rod and magnetic suction disc, and the magnetic force spreading rod is the club shaped structure being made by magnet, and the upper face of magnetic suction disc is provided with magnet layer.The magnetic suction disc is the rectangular box-like structure of uncovered.The bottom outside center of the magnetic suction disc is equipped with handle.Spreader structure described in the utility model is simple, low manufacture cost；And in use, magnetic force spreader can directly sterilize with one piece of culture medium, avoid traditional link that spreader sterilizing is burnt using alcolhol burner, time saving, laborsaving, and save experimental cost.In coating process, culture dish is in closed state, avoid with air and the external world contact, pollution probability can be effectively reduced.
Description
Technical field
The utility model belongs to Bioexperiment device technical field, and in particular to a kind of novel flat-plate magnetic force spreader.
Background technique
Plate culture is that culture medium is made to form surface in sterile culture dish using agar or plant gel, so
Cultivate various microorganisms, including various bacteriums, fungi, mould etc. on that plane afterwards.Plate culture is microorganism and other
One of most common biology techniques of field of biology.The maximum problem encountered in plate incubation is exactly the dirt of miscellaneous bacteria
Dye, often caused by operator, misoperation or sterilization of instruments are not thorough and cause living contaminants during the experiment.
It is being easiest to pollute when being coated on plating medium using spreader, main reasons is that: first:
Spreader disinfection is not thorough, especially the long handle of spreader, if disinfection is not thorough, the bacterium being infected on handle in coating process
It is easy to be blown off by sterile wind on culture medium and pollute；Second: the lid of culture dish is constantly in open shape in operating process
State, and air contact time is too long also increases the probability of pollution；Third: operator portions such as hand, wrist in operation
Position disinfection is not thorough, and either in the super-clean bench of vertical ventilation or horizontal blast, is all easy to the bacterium that will be infected on hand
It blows off on plating medium, pollutes.
Summary of the invention
In view of the above technical problems, the purpose of the utility model is to provide a kind of novel flat-plate magnetic force spreaders.This reality
With the novel magnetic force spreader greatly reduce in plate incubation pollution (not only consider germ contamination, it is also different
Pollution it is also bad).
In order to solve the above technical problems, the utility model is achieved using following technical scheme:
The utility model provides a kind of novel flat-plate magnetic force spreader, it includes magnetic force spreading rod and magnetic suction disc, institute
Stating spreading rod is the club shaped structure being made by magnet, and the upper face of magnetic suction disc is provided with magnet layer.
Compared with prior art, the advantages of the utility model and spreader structure described in the utility model is had the technical effect that
Simply, low manufacture cost；And in use, magnetic force spreader can directly sterilize with one piece of culture medium, avoid tradition
The link that spreader sterilizing is burnt using alcolhol burner, it is time saving, laborsaving, and saved experimental cost.In coating process, culture
Ware is in closed state, avoid with air and the external world contact, pollution probability can be effectively reduced.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the magnetic suction disc；
Fig. 2 is the structural schematic diagram of the magnetic force spreading rod.
Wherein, 1, magnetic force spreading rod；2, magnetic suction disc；3, handle；4, magnet layer.
Specific embodiment
The technical solution of the utility model is further described in detail in the following with reference to the drawings and specific embodiments.
Embodiment 1
As illustrated in fig. 1 and 2, novel flat-plate magnetic force spreader described in the utility model includes that magnetic force spreading rod 1 and magnetic force are inhaled
Disk 2, the magnetic force spreading rod 1 are the club shaped structures being made by magnet, can be in one layer of plastics of outer layer covers of magnetic force spreading rod
Carry out high temperature, high pressure sterilization.The upper face of magnetic suction disc 2 is provided with magnet layer 4.The magnet layer is rectangular sheet magnetic
Iron can rely on the movement of Magnetic force tracting magnetic bar.The size of the rectangle magnet and the bottom of magnetic suction disc inner surface
Area equation.The magnetic suction disc 2 is the rectangular box-like structure of uncovered.It installs in the bottom outside center of the magnetic suction disc 2
There is handle 3, the handle is semi-circular shape, facilitates hand-held.
The application method of novel flat-plate magnetic force spreader described in the utility model is as follows:
(1) when needing to carry out plate culture, magnetic force spreading rod is put into sterilization cassette and is sterilized together with one piece of culture medium, together
When can sterilize a tweezers.
(2) after bacterium of having gone out, inverted plate starts to be coated culture after waiting the plating medium in culture dishes to solidify.
Firstly, the bacterium solution cultivated will be needed to be added in plate using pipettor, then with sterilized after both hands disinfection
Magnetic force spreading rod after sterilizing is clamped into culture dish by tweezers, covers the lid of culture dish.
Secondly, left hand picks up culture dish, the right hand holds the semicircular ring of magnetic suction disc, and the one side of carry magnet upward, is placed on
The bottom of culture dish drives the magnetic force spreading rod in culture dish mobile, will need to cultivate using the magnetic force of magnet on magnetic suction disc
Bacterium smear uniformly, magnetic force spreading rod can be taken out with tweezers as needed after the completion of coating, can also not have to take out, reduce
The probability of pollution.
Spreader production described in the utility model is simple, at low cost, and in use, magnetic force spreader can direct and training
One piece of sterilizing of base is supported, traditional link for burning spreader sterilizing using alcolhol burner is avoided, it is time saving, laborsaving, and saved reality
Test cost.In coating process, culture dish handles closed state, avoid with air and extraneous contact, can effectively reduce
Pollute probability.
Above embodiments are only to illustrate the technical solution of the utility model, rather than are limited；Although referring to before
Embodiment is stated the utility model is described in detail, it for those of ordinary skill in the art, still can be right
Technical solution documented by previous embodiment is modified or equivalent replacement of some of the technical features；And these
Modifications or substitutions, the utility model technical solution claimed that it does not separate the essence of the corresponding technical solution spirit and
Range.
