How to dilute medical alcohol How to dilute 99 medical alcohol into 75 disinfectant alcohol?

It is necessary to calculate the ratio dilution according to the original concentrationTake 100ml of 95% diluted into 75% medical alcohol as an example, dilution with the following:

The calculation is as follows:

100ml of 95 alcohol contains alcohol: 100 95 95;

If there are 95 grams of alcohol in 75% alcohol, the total weight is: 95 75;

So the total amount of water that needs to be increased is: (Distilled water).

Here's how:1.If you buy alcohol with a concentration of 90%, dilute it according to the instructions before use.

2.A 75% alcohol swab or alcohol can not only kill the virus, but also be cheap.

3.Wipe down doorknobs, tabletops, elevator buttons, etc., without spraying heavily in the air or on the body.

4.It is not recommended to spray and disinfect clothing with alcohol, as burning may occur in the event of an open flame or static electricity.

5.The use of alcohol indoors needs to be ventilated, kept away from hot objects, and never come into contact with open flames.

6.Behaviors such as smoking, smoking, and using electric mosquito swatters cannot be carried out immediately after spraying high-concentration alcohol.

7.Clean up the surrounding flammable and combustible materials before use, and turn off the power before disinfecting the surface of the electrical appliance.

8.Used towels and other cleaning tools should be washed with clean water and left to dry in a ventilated place.

It can be diluted according to 99% of the number of millilitersTake 100ml of 99% alcohol as an example and dilute it into 75% alcohol, the specific method is as follows:

100ml of 99 alcohol contains alcohol: 100 99 99;

If there are 99 grams of alcohol in 75% alcohol, the total weight of the vertical branches is: 99 75 132ml;

The total amount of water that needs to be increased is: 132 100 32ml. (Distilled water).

So if you want to mix 100ml of medical alcohol.

It can be diluted as above and calculated according to the above formula.

Dilute it. For example, take 100ml of 95 alcohol, 95 , you need to add water, and you will be prepared with 75 degrees of alcohol.

Alcohol dilution is the process of adding a certain volume of high-concentration (95%) alcohol (95% alcohol in a 500ml package) to a certain volume of water to make a low-concentration (e.g. 75%) alcohol.

For example, to prepare 100 ml of 75% alcohol: the formula is calculated to obtain the volume of 95% alcohol v = (75%x100ml) 95% = ml.

Dilution operation: Add ml to a 100 ml dry and clean graduated cylinder95% alcohol, diluted with distilled water to 100 ml of engraved lines. It is then transferred to a reagent bottle and labeled.

The alcohol can be diluted by adding water.

It is generally recommended to use sterile distilled water to dilute alcohol, if there is no sterile distilled water, you can also dilute the alcohol after high temperature disinfection with tap water, because if you use tap water directly, there may be bacteria or other substances in the tap water, which may have an impact on the disinfection effect of alcohol. happens.

How to store ethanol:

1.A lot of ethanol storage.

Many of the ethanol used by the company need to be stored in a dangerous goods warehouse, and the warehouse should be completely cleaned and cleaned, and it is forbidden to close the paint organic compounds and store them in a cool, naturally ventilated warehouse. Eliminate fire and pyrogen. The storage temperature does not exceed 30, and the air humidity does not exceed 80%.

The packaging is tightly sealed and cannot be touched with gas. It should be stored separately from oxidants, specific metal powders, acids, and chemicals, and should not be mixed. The storage area should always have suitable raw materials to rescue the spills.

2.Storage of small amounts of ethanol.

I and the small amount of ethanol used in the home storage only need to pay attention to the elimination of pyrogens, switching power supplies and areas that are not easy for children to touch, the amount of ethanol I apply is relatively small, not easy to have any big injuries, but the home needs to be equipped with firefighters, and firefighters need to be checked frequently, just in case.

It can be diluted according to 99% of the number of millilitersTake 100ml of 99% alcohol as an example and dilute it into 75% alcohol, the specific method is as follows:

100ml of 99 alcohol contains alcohol: 100 99 99;

If there are 99 grams of alcohol in 75% alcohol, the total weight is: 99 75 132ml;

The total amount of water that needs to be increased is: 132 100 32ml. (Distilled water).

Therefore, if you want to mix 100ml of medical alcohol, you can dilute it as above and calculate the ratio according to the above formula.

Dilute with water.

1 volume of medical alcohol, add volume of water to mix (e.g., 1L of medical alcohol plus 320ml of water).

That's 75 percent of disinfectant alcohol.

It is to use 75ml of alcohol and 25ml of pure water or cool boiled water. Generally, diluted alcohol is used for disinfection, generally at 70-75%. Dilute in this way.

This is the analysis of pure grade high-purity alcohol, of course, it can be diluted into a 75% solution for disinfectant. With such high purity, you can drink it as liquor with water! Even the commercially available liquor has a much higher content of these impurities.

Just use clean water and you're good to go. It can be one glass of alcohol, three glasses of water. It doesn't matter if the water is hot or cold.

Hope you are satisfied

How 99% alcohol dilutes 75%: hear what the doctors have to say.

The effective disinfection concentration of medical disinfectant alcohol is 75%, so it cannot be diluted after purchasing, otherwise it will not play a disinfection role.

Alcohol can be mixed with water in any proportion, and if it is used for disinfection, the alcohol with a concentration of 75 has the highest disinfection effect, so it is often used in medical treatment and is called medical alcohol. It is recommended to spray directly with 75 alcohol.

In the near future, try to stay at home and do not go out, and do not go to crowded places. Alternately open windows for ventilation indoors. Have a regular schedule and avoid staying up late and being tired. Avoid unhealthy lifestyle habits such as smoking, alcoholism, etc.

100ml of 99 alcohol contains alcohol: 100 99 99;

If there are 99 grams of liquor in 75% alcohol, the total weight is: 99 75 132ml;

The total amount of water that needs to be increased is: 132 100 32ml. (Distilled water).

Therefore, if you want to mix 100ml of medical alcohol, you can dilute it as above, and calculate it according to the above formula.
