The thermometer disinfectant immersion solution is changed several times a week

Thermometer. The disinfectant soaking solution needs to be changed about twice a week.

The concentration of alcohol disinfectant solution for thermometers is best to use about 75% alcohol. After each use of the thermometer, it can be used by other family members. You can also choose to soak in medical alcohol.

2-3 minutes, can play a better role in disinfection. The optimal concentration of medical alcohol is 75%, and 75% alcohol is mainly due to the fact that it can enter the cells of bacteria.

It can completely denature the proteins of bacteria and destroy bacteria. If the concentration is too low, the effect will not be obvious. If the concentration is too high, such as 90% alcohol, the effect is too strong, and it may denature only the outermost proteins of the cell. Whereas.

It depends on what kind of disinfectant you are using. However, a typical thermometer soaked in 75% alcohol is good enough twice a week.

Considering the volatilization or decomposition of the disinfectant, the effective concentration of the disinfectant will gradually decrease, and the concentration of effective disinfection may not be reached for a long time, so it is necessary to regularly test the content of the active ingredients in the disinfectant solution during use (such as chlorine-containing disinfectant, peracetic acid, etc. can be used with G-1 test strips). Once it is found that it does not meet the requirements, it should be replaced with a new disinfectant immediately.

As for the specific number of weekly replacements, it should be determined according to the ambient temperature (in general, the higher the temperature, the faster the disinfectant volatilizes), the type of disinfectant (such as peracetic acid is very volatile), the frequency of the immersion thermometer, etc., and can be determined after exploration.

There is no reaction between the two, and the mercury in the thermometer is in contact with the solution.

Dilution concentration 200 times) available chlorine preparation: Xiaojiajing (stock solution) 10ml water 990ml(100-fold dilution concentration) available chlorine preparation:

Xiaojiajing (stock solution) 20ml water 980ml(diluted 50 times) available chlorine, because the formula is complex. It is recommended to buy the finished product directly, I hope it can help you, and I wish you a happy life.

A wipe with a cotton ball dipped in alcohol.

Reason: B is washed and dried with tap water, although it does not exceed the range, but it cannot achieve the purpose of disinfection, so it is wrong.

The working principle of the c. thermometer is to use the thermal expansion and contraction of the liquid, and its range is 35 42; Since the temperature of the boiling water is 100, it is out of the range of the thermometer and will damage the thermometer, wrong.

d The temperature of the flame of the alcohol lamp far exceeds the range of the thermometer and can also damage the thermometer, wrong. Hope!
