Description
Technical field
The present invention relates to a kind of bacterium spreading rod with temperature sensor, belong to experiment apparatus technical field.
Background technology
In the experiment such as microbe to screen, antibiotics susceptibility test, need the liquid sample containing microorganism to coat solid culture planar surface.The bacterium spreading rod that existing market is sold is roughly divided into two kinds, and a class is disposable hand-held plastic-coated rod; Another kind of is glass or metal repeatedly used spreading rod.The two Problems existing is and is unfavorable for once carrying out a large amount of Bacterial Transformation experiments.Disposable plastics bacterium spreading rod quantitatively can meet requirement of experiment, but waste material, also easily cause pollution to environment owing to spreading rod speckling with bacterium in addition.Glass or the spreading rod of metal products are then difficult to once prepare dozens of spreading rod, Reusability after although metal bar can overdo, but this kind of spreading rod temperature fall time after overdoing is long, and operator are difficult to ensure that the temperature of spreading rod drops to less than 37 DEG C, if temperature drift, easily scald the strain bio of dead coating, thus affect experimental result, if cooling time is oversize, waste a large amount of waiting time; Glass spreading rod on the one hand can by soaking 75% alcohol to reuse, but each treatment time needs more than 20 minutes, Reusability after another aspect glass spreading rod also can overdo, but so just there is same problem with metal coated rod, in sum, there is all drawbacks in existing method, has had a strong impact on the accuracy rate of conventional efficient and experimental result.
Therefore, be badly in need of a kind of easy to use, the bacterium spreading rod of cooling degree can be judged intuitively, easily, solve problems of the prior art, ensure carrying out smoothly of microbial culture experiment, the accuracy of increasing work efficiency and testing.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of bacterium spreading rod with temperature sensor.
To achieve the above object of the invention, the technical solution used in the present invention is: a kind of bacterium spreading rod with temperature sensor, the coating end comprising handle and be connected with handle, described handle and coating end are structure as a whole, described coating end is in equilateral triangular shape, cavity is equipped with in described handle and coating end, temperature sensor is provided with in the cavity of described coating end, temperature indicator and comparator circuit is provided with in the cavity of described handle, described temperature sensor is electrically connected with an input terminus of comparator circuit, another input terminus of comparator circuit connects reference voltage, the output terminal of described comparator circuit is electrically connected with the driving circuit of described temperature indicator.

Preferably, the length of described handle is 15 ~ 20cm.
Preferably, the limit of described coating end is rounded, and its diameter is 3 ~ 5mm.
Preferably, the grip part of described handle is provided with anti-skid structure.
Preferably, the angle between described handle and described coating end place plane is 100 ° ~ 180 °.
Above, when the temperature of coating end is more than 37 DEG C, temperature indicator is red, when temperature is at 37 DEG C or following, the color of temperature indicator is green, can arrive judge that whether coating end is in the safety temperature of bacterial organisms fast according to the color experimenter of temperature indicator.
Principle of work of the present invention is as follows: temperature sensor exports corresponding voltage according to current temperature, and current magnitude of voltage is compared with the magnitude of voltage preset, if higher than the magnitude of voltage preset, comparer then exports high level, and driving circuit (red) starts, and sends ruddiness; If current magnitude of voltage is lower than the magnitude of voltage preset, then comparer output low level, driving circuit (green) starts, and sends green glow.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1. the present invention is coated with end in equilateral triangle shape, while guarantee bacterium liquid Painting effect, also improves the stability that bacterium spreading rod slides in culture dish;
2. one aspect of the present invention can prevent the too high and boiling hot dead bacteria effect experimental result of temperature being coated with end, can judge that whether coating end is in safety temperature according to temperature indicator on the other hand, greatly shorten the waiting time, the accuracy of increasing work efficiency and testing;
3. the grip part of handle of the present invention is provided with anti-skid structure, can increase frictional force, ensures the stability of operation;
4. structure of the present invention is simple, and cost is low, is convenient to promote the use of.
