How many drops per ml: counting rules

Usually the question of how many drops in 1 ml, occurs in those who have been prescribed to take a certain medicine in milliliters, while in the packaging there is no corresponding dispenser. But for different solutions the amount of droplets can vary, it will depend on the composition of the liquid, its density, on the surface tension, on the external forces and on the diameter of the tube from which they drip. Therefore, it is impossible to say unequivocally how many drops per ml.

Even in the times of the Soviet Union, a table was created in which the number of drops for various liquids, including medicinal solutions, was indicated. So, if only 20 drops are in 1 ml of distilled water , then in the same volume, wormwood tincture is 56, and medical ether is 87. One drop of ordinary water is about 0.03-0.05 ml, an alcohol solution is 0.02 Ml.

If a measuring cup or a pipette with the number of ml of the drug purchased does not come with the medicine, these data are not indicated in the instructions to the preparation, then it is best to measure the required quantity with a conventional syringe. When you need to measure more than 1 ml, you can use a conventional 2 or 5-cc syringe, and to measure a smaller volume or need to determine exactly how many drops per ml, it is better to take an insulin syringe, the volume of which is 1 ml, with clearly designated decimal divisions .

If you need to drink a certain amount of drops, and in the kit contains no drip dispenser or pipette, you can simply dial 1 ml of the solution into the insulin syringe and measure how many drops in 1 ml. Based on the data obtained, you can already figure out how many it is necessary to collect tenths of ml in a syringe in order to obtain the desired number of drops. For example, you need to take 15 drops of a certain medicine. Having typed in an insulinic syringe without a needle 1 ml, carefully dig out its contents, counting thus quantity or amount of drops. Let's say that you got 50 drops for this amount of medicine. By composing a simple proportion:

50 drops - 1 ml;

15 drops - x ml,

We get 15k * 1ml / 50k = 0.3ml. This means to get 15 droplets, you need to get into the syringe 0.3 ml of the solution, but before the first reception, it is better to separately recalculate how many drops you will get from the volume you have collected. Perhaps you were mistaken in calculating how many drops in 1 ml. This method of calculation is suitable for any type of liquid, with its help you can measure any number of drops, no matter how many fit in one milliliter. This method is very convenient, for the next dose of medication you do not have to recalculate the drops, just type the necessary volume into the syringe and drink it.

It is also convenient enough to give small children the same way: they better insert the syringe directly into the mouth, directing the flow of liquid not in the throat, but behind the cheek. So the kid can not spit out the medicine and will not choke. If the dosage of the drug is more than 5 ml, then it is more convenient to use a syringe instead of a cutlery for its use. So, in a typical teaspoon, 5 ml of liquid is placed, and in the dining room - 15.

If you need translation, how many in 1 gr. Ml, it is worth considering that the weight will depend on the density of the substance. So, 1 gram of water corresponds to one milliliter, but 1 ml of alcohol is 0.88 grams.
