In every laboratory a series of instruments is required to carry out each and every one of the tasks that are elaborated in it, if you are a chemistry teacher, a science professional or you simply like to learn about this subject by doing small experiments, then a dropper will come in handy for you .

Thanks to this extraordinary tool you will be able to have more exact control of the doses that you have to apply in each mixture. The misuse of an instrument like this can cause serious damage to both our physical integrity and that of our colleagues, for this reason you must be extremely careful when handling it.

In laboratories it is very useful because it helps to control the exact amount of solutions that are needed, without running the risk of exceeding the amount required in each case. In medicine it is very common to use the dropper to provide liquid remedies or syrups to young children, newborns and even pets.

What is a Dropper?

The dropper is a hollow tube that has a conical shape on one of its tips and on the other it has a rubber thimble or a knob that serves to control the amount of liquid that you want to add to a certain composition.

This instrument is also known as a dropper, it comes in different dimensions and can be made of various materials such as glass, aluminum, plastic or silicon.

In every laboratory there should be a dropper, as it allows adding indicator and reagent liquids or moving any product from one container to another without the fear of damaging the mixture or creating any reaction by placing more or less than the requested amount.

What is a dropper for?

This magnificent laboratory instrument is used to transfer small amounts of substances from one place to another, having the control and the assurance that it is going to be dripped without excesses so as not to risk damaging the mixtures or the experiment.

Its use is completely limited in the case that greater precision is required in the amount of liquid to be poured, since for these cases more appropriate instruments such as the burette or the pipette are suggested .

Fortunately, there are currently a large number of excellent distributors of laboratory materials and equipment, who sell the best quality, guaranteeing that the results obtained from tests and experiments are the most satisfactory, since there is no risk of contamination or false measurement. .

Equipment that is not of good quality complicates investigations and makes the scientist work harder to obtain the result he hopes for.

How does a dropper work?

This glass tube, which has a kind of rubber cap at one end, and a conical tip at the other end, allows the solutions to be sucked and thrown at a certain quantity .

It is a very easy-to-use tool, for this you only need to press a little the rubber that is at one end of the dropper, submerge the tip in the liquid you want to transport, release the rubber so that it sucks and the liquid can remain in the dropper.

To place the liquid in the desired place, you just have to gently press the rubber and it will fall drop by drop, allowing you to have control of the amount of solution you want to place. It is important to know that since it does not have any warning, the procedure can be lost if this instrument is misused and care is not taken when mixing.

The dropper must always remain clean, after each use it must be washed very well to avoid contaminating the experiments or having any reaction due to improper mixing of any of the previous solutions in which it has been used with the one being done in that moment.

Dropper uses

In laboratories where chemical products are used, the dropper is an indispensable tool since it is used to add the reagents that need to be handled with great care and accuracy.

  • Its use is not recommended when it is necessary to have total precision in the amount of substance to be placed. In this case, the instruments recommended for this should be used.
  • It is used to transfer and drop small amounts of any liquid.
  • The dropper is widely used in laboratories where liquids, reagents and small amounts of any product need to be added.

The dropper is an essential instrument in any laboratory, it will help you to simplify each task that requires transport for mixing solutions, and when used properly it will limit any type of accident in a very effective way, creating a safe work environment for everyone in the lab.

Dropper types

In general, these utensils are marketed together with the universal dropper bottles. They are made with materials that are not reactive such as glass and plastic, in this way contamination of the samples with other substances is avoided, although in some cases they can be found in other materials.

There are two types of droppers:

  • Those with a straight tip: with this one the dripping is fast and it is generally a bit complex to control the amount of liquid that is going to be supplied to the mixture, it must be well controlled.
  • Those with a curved tip: with this design the supply of the liquid is slower than that obtained with the rear tip droppers, thus making it easier to control and manipulate the samples .

Features of a dropper

Scientific and technological advances have allowed the progress of societies, very few are those who know that being in a laboratory is not easy work, since it is necessary to meet certain requirements that allow science to be carried out in a positive way and safe for mankind.

Having the instruments that are needed in any laboratory is one of those requirements and among the main ones is the dropper, a very simple tool but at the same time super essential for any experiment or test that you want to carry out and that needs to transfer liquids from a side to side with some accuracy.

It is a thin cone, usually made of glass or white or amber plastic, with a rubber cap or thimble, specifically eg polypropylene and with a tip in some cases straight and in others curved.

It is easy to clean , to do so it is not necessary to disassemble it and run the risk of losing any part, with the easy maintenance, more working time and less cleaning time are guaranteed.

Importance of a dropper

The scientific laboratory is a space that must be very well equipped with laboratory instruments, machines and materials that allow any type of research to be carried out, being very easy to handle but at the same time they are very expensive.

Having quality drippers and knowing how they work is extremely important, it will guarantee that their useful life is longer and also the results of the research being carried out will not be affected .

Being able to calculate with total accuracy the solutions of an experiment in small quantities will be an easy task , whether the dropper with a straight or curved tip is used depending on the situation, without having the worry of spilling liquids or creating unfavorable reactions by making a misapplication of quantities.

Born and raised in Brussels in an English family, I have always lived in a multicultural environment. After several work experiences in marketing and communication, I came to Smart Water Magazine, which I describe as the most exciting challenge of my career.
I am a person with great restlessness and curiosity to learn, discover what I do not know, as well as reinvent myself daily, someone who is curious about life and wants to know. I enjoy sharing knowledge.
This is my personal project but I also collaborate in other blogs, it is the case, the most important web on water currently exists in the US, if you are interested you can read my articles here.
