Abstract
The utility model discloses a digital temperature displaying coating rod which comprises a triangle scraper working area (1), a handle (3), a platinum resistor probe (2) internally installed inside the triangle scraper working area (1) and an electronic display screen (4). The platinum resistor probe (2) is connected with an analog to digit (A/D) conversing circuit internally installed inside the handle (3). The A/D conversing circuit is connected with the electronic display screen (4). The digital temperature displaying coating rod has the advantages that in the process of sterilization by burning the coating rod, whether a sterilization temperature is reached can be judged through a temperature displayed on the coating machine, and therefore burning time can be controlled; in the process of coating rod cooling, the temperature is displayed to avoid a false judgment of the temperature due to the fact that microorganisms can be burnt to death if the temperature is too high; and waste of time because of cooling for a long time is avoided.
Description
Technical field
The utility model relates to a kind of digital display temperature indicating spreading rod, belongs to experiment apparatus technical field.
Background technology
Spreading rod (glass spreading rod, stainless steel spreading rod, spreader, spreading rod) is multiplex to use instrument in scientific research and some laboratory of universities and colleges, is a kind of indispensable instrument in the Experiment on Microbiology middle plateform coating method.Be used for needing the calcination sterilization before the use at agar surface coating bacterium liquid, then naturally cool to the following flat board that could be used for of certain temperature and be coated with microorganism, the grasp of temperature by rule of thumb.
Laboratory glass spreading rod commonly used is made with glass, and shortcoming is frangible, and can not judge the sterilization degree according to temperature conditions in the calcination process; Can not accurately judge temperature in the process of cooling, excess Temperature easily scalds dead microorganism, expends time in too for a long time such as cooling.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of digital display temperature indicating spreading rod for the deficiencies in the prior art.Adopt following technical scheme:
A kind of digital display temperature indicating spreading rod comprises triangle spatula workspace (1), handle (3), is built in triangle spatula workspace (1) inner RTD probe (2), electronic display (4); RTD probe (2) connects the A/D translation circuit that is built in handle (3) inside, A/D translation circuit connecting electronic display screen (4).
The beneficial effects of the utility model are:
One judges whether to reach sterilising temp by the shown temperature of spreader in the process of calcination spreading rod sterilization, the control calcination time.
Its two, the cooling spreading rod process in, displays temperature avoids judging by accident temperature, dead microorganism is scalded in too high meeting; Avoid cooling to lose time too for a long time.
Description of drawings
Fig. 1 is the structural representation of the utility model digital display temperature indicating spreading rod.
Embodiment
Below in conjunction with specific embodiment, the utility model is elaborated.
With reference to figure 1, digital display temperature indicating spreading rod comprises triangle spatula workspace 1, handle 3, is built in RTD probe 2, the electronic display 4 of triangle spatula workspace 1 inside; RTD 2 temperature sensors of popping one's head in change, and are treated to the digital temperature data by the A/D translation circuit that is built in handle 3 inside, show triangle spatula workspace 1 Current Temperatures by electronic display 4.
Can know directly and accurately like this temperature of spreader triangle spatula workspace 1, whether the sterilizing works that can judge accurately spreader when doing Experiment on Microbiology is thoroughly finished, and can judge accurately before smearing microorganism whether applying area is reduced to suitable temperature, scalded dead by high temperature to prevent microorganism.
The another one example, in the making of the spreading rod of routine, add high temperature resistant reversible thermochromic material (organic or inorganic material), perhaps directly make spreading rod with this material, can in certain temperature range, produce look and become (presenting distinct colors under the different temperature), in order to the surface temperature of spreading rod is had more intuitively judgement.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
Claims (1)
