Reagent Bottle

November 1, 2021

Many substances and elements are found in the laboratory, including reagents . In the field of chemistry, they are substances that are used to generate a reaction when they come into contact with another substance, allowing it to be detected. These should be stored in a reagent bottle, where they can be preserved.

Although these bottles are also used to contain solutions, they are mainly used to contain reagents, as the name implies. They are instruments highly used in the area, so it is present in any laboratory, due to its usefulness and importance in the care and preservation of said substances.

What is a Reagent Bottle?

Reagent bottles are instruments that have been used by humanity for some years now and this does not seem to change thanks to their practicality. These are mostly glass containers with a cylindrical shape, which come with a lid to keep the contents safe. Caps can be screw, dropper, or frosted. The latter close under pressure.

Reagent bottles have high chemical resistance , this is the ability to resist impregnation, corrosion and erosion caused by some substances. Due to the type of substances that must be placed in the reagent bottles, it is not possible to fill any bottle manufactured for another purpose, this could compromise the substance.

What is the Reagent Bottle for?

The reagent bottle has special characteristics that make it suitable for containing these substances. Like the glass it is made of, it is commonly borosilicate glass that is highly resistant. Safe storage of reagents is a must as many are hazardous substances.

The reagent bottles are labeled with the specifications of the substance they contain, they even have colored bands to warn of possible dangers when they come into contact with the substance. To give you an idea I will proceed to mention them:

  • White: Indicates corrosion
  • Yellow: Reactivity (dangerous with combustible substances)
  • Red: Fuel
  • Green: Safe
  • Blue: Toxic

Depending on their condition, each one has special storage measures, for example, reagents with yellow should not be close to those with a red band as there is a danger of combustion if the substances come into contact. The bottles, then, apart from containing the substances safely, provide pertinent information about them if they are properly labeled.

Reagent Bottle Uses

These have a specific use that is to contain reagents , although they are also used to contain solutions; which are the product of the mixture of pure substances that do not react with each other. Reagent bottles are used mostly in the pharmaceutical, chemical and general medicine fields, as well as in highly demanding laboratories.

There are many disciplines that use it in their work, even to contain substances that are not those mentioned above. This thanks to the resistance of its material, which is stronger than the common glass jars used to package products.

Reagent Bottle Types

Reagent bottles can be classified in two ways, by their labeling or by the color of the glass . The first form indicates rather the type of reagent than a significant difference in the glass, because as I indicated previously, what these colored bands do is to warn if the substance inside is dangerous or not and to what degree.

On the other hand, the difference in the color of the glass divides them into two types , the common glass that is transparent and the opaque amber glass, which is used to prevent photosensitive substances from being affected by light. Another difference would be the type of lid that the bottle has, whether it is screw, dropper or frosted and it will depend on how sealed the material is required or if it needs to be vacuum packed.

Reagent Bottle Features

When storing care materials, these jars must meet certain characteristics to be able to contain these substances, minimizing the risk. Their manufacture takes this point into account and the industries that are responsible for their mass production and distribution must meet the requirements.

The main characteristics of a reagent bottle are:

  • Chemical resistance: Not be damaged by corrosive substances
  • Resistance to temperature changes
  • Low heat expansion: no risk of material deformation due to exposure to high temperatures
  • Sterilizable: for instrument cleaning

Their capacities can be from 50ml to 20000ml so they have a variety of sizes; the colors available on the market are transparent and amber, for photosensitive substances. Depending on the brand they will have specific differences but they are usually minimal things since a standard procedure is followed in their realization.

Importance of the Reagent Bottle

Historically the reagent bottle has been a highly used utensil by almost all cultures, whether they are made with different materials, or have different names. And it is that its variety of use and great utility is unquestionable; From groceries to valuables, jars have served to efficiently store countless items.

In medicine its use is also remote, as in the case of the albarelo, a type of bottle used by apothecaries to store drugs (solid) and covered with parchment. The profession of the doctor and the chemist requires a large quantity of substances that must be conserved and transported and the bottles are the ideal medium.

As more and more substances are used and it is necessary to make procedures more complex, instruments that are in line with the requirements are also needed. The flask is a very simple and adaptable instrument; the filmmakers have been able to adapt them to the needs by using a resistant, waterproof and sterilizable material when creating the reagent bottle.

In short, it is an instrument that is not lacking in all types of laboratories, pharmacies, bioanalysis, chemistry, biology or marine sciences thanks to its versatility and intuitive use.

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.
