Laboratory washing flask, how to choose it?

November 2, 2021

The Laboratory Wash Bottle is an essential laboratory tool for maintaining beakers, flasks and test tubes. These are equipment exposed to numerous residues and chemical substances that are reducing its useful life, which is why you need a washing bottle with distilled water capable of washing and completely cleaning the contents.

It is a bottle that should never contain any other type of liquid that is not necessary for the cleaning phase, since its materials do not withstand, for example, the substances in the test tubes. It could damage both the material and the test being carried out. It is also not recommended to open it too much, much less leave it open for a long time.

If you want to know the main characteristics of a laboratory washing bottle, you are in the right place. Next, we will talk about this important laboratory utensil that cannot be missing from the inventory stock and that must be handled in the correct way to avoid its loss or spoilage. Knowing the uses that we will break down will help you whether you are a student or a professional in the field of chemistry, physics, medicine or biology.

What is a laboratory wash bottle?

The laboratory wash bottle, also known as a wash bottle or tank, is a pressure flask that has a nozzle similar to straws that is used to rinse laboratory glassware with distilled water.

It is usually made of plastic or glass, depending on the type of content that is stored, its classification depending on that factor. On the other hand, its design is cylindrical with a lid and a hole in the middle where the nozzle emerges and runs the water destined to clean the main laboratory utensils that leave residues, dust and chloroplasts of biological samples.

Unlike other types of laboratory instruments, it is used both in the field of chemistry and biology, since it is necessary to be able to wash correctly. As mentioned, they should not be uncovered much, especially so that the content does not leak or leave it open.

What does the laboratory wash bottle contain?

The laboratory wash bottle stores distilled water , which is the composition of substances that are based on H2O molecules. But that, through a process of distillation, have been purified or washed. Making them excellent for washing instruments that have undergone tests with chemical and biological residues. Of course, this type of water is not used as a drink, but for hygiene or in filters to remove the parts of calcium and magnesium ions. An example of this type of water is cleaning alcohol .

Also, slightly less common, but which is still part of the content stored in the tank, are solvents . Chemical substances that are diluted in solute, be it solid, liquid or gaseous, forming a solution. The most common are hexane, methanol, and ethanol. Depending on the brand and the purpose of the wash battle.

What are the laboratory washing bottles like?

As their name says, they are jars or cylinders that are enclosed by a plug in the middle that, at the base of the middle, begin to form a small straw of the same material. This straw or nozzle allows the water to escape towards glass and crystal utensils.

The size of this bottle will vary in different presentations, ranging from 30 milliliters to about 1,000 milliliters. It is considered the best option to be able to contain demineralized water, but it works the same as a dispenser at the time of use after a day of work in the laboratory.

Types of laboratory washing bottles

There are several classifications of the tank, either by the material or by the content of the bottle. This can store so much alcohol, distilled water and the odd solvent. Next, we will focus on the types of laboratory wash bottles by the material in which they are made.

Glass washing bottle

The glass bottle is a version of the common laboratory wash bottle, but it is made of an inorganic material, harder than plastic, which makes it susceptible to drops and bumps. It is characterized by being transparent, amorphous and is ideal for storing liquid substances such as alcohol.

Plastic washer bottle

It is the most common version of t-shirt used in laboratories, as it is resistant to falls, but less hard than glass. It is made of polyethylene, a variety of organic, synthetic or semi-synthetic compounds. They are the ideal choice for solvents that are more reactive and could influence the life of the material.

Uses of the laboratory wash bottle

Next, we will talk about the main uses of the t-shirt so that you have a better notion about the subject in question.

  • Cleaner . It is the main use of wash bottles, being necessary to maintain the hygiene of laboratory glassware and associated equipment. To do this, the bottle is squeezed onto the test tube and rinsing begins.
  • Disinfectant . The jars are used to disinfect materials that have been damaged by chemical or biological tests with which external residues remain.
  • Level meter . With the tank you can bring the solutions that are being made to a final volume. Of course, always in small quantities.
  • Liquid control . Since the t-shirt has measurement markings on the bottle, it helps researchers control the amount of liquid to be used in a wash.

T-shirt care

The main care of the bottle is not to keep it for too long with the same substance, especially if it has the cap open, as it could damage the stored content. And, speaking of solvents, in case they are under pressure, it is necessary to release the lid so that the contained steam finds an outlet.

Nor can we forget the identification of the t-shirt with its proper name and content inside. Here, in case the same bottle does not have it, you can design it by printing an instrument where it indicates the characteristics of the bottle. Including vital data such as the type, content and storage capacity of liquid.

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.
