Laboratory beaker

November 2, 2021

A beaker or beaker is a fundamental element in a well-equipped laboratory, because it has several functions within it. It can be used to measure, heat, mix, and form precipitates.

What is it?

It is a clear borosilicate glass container with a wide mouth and cylindrical shape. It has a scale on the outside so it can be used to measure liquids that do not require too much precision. It is used to heat and mix substances and to form precipitates.

Beaker Features

They can be made of plastic or borosilicate or pyrex glass. This material begins to soften at 821ºC. They also have Teflon components and other corrosion resistant materials.

They have a cylindrical shape, a flat bottom, and a wide mouth. They have various capacities and various sizes. They range from 1 Ml to liters of capacity. The most common and most used are those of 50mL, 100mL, 250mL, 500mL.

It should be noted that they are graduated vessels, but without calibration, so they are not useful for accurately measuring volumes. This means that, for example, a 250 mL beaker will have divisions of 50, 100, 150, 200 and 250 mL, but they are approximate marks and should be taken only as a reference.

Uses of the beaker

Are used to:

  • Contain different types of liquids.
  • Obtain pre-citations from the reaction between different substances.
  • To transport liquids to other containers.
  • Contain various liquids and chemicals.
  • Heat, dissolve, or prepare chemical reactions.

How to use the beaker

If you want to heat a liquid or substance with a bunsen burner, you should use an asbestos grill to achieve even heat distribution.

Do not subject the beaker to sudden changes in temperature as it may fracture. Hold it with gloves if it is hot.

When preparing reactions and solutions never focus on your body or that of a partner.

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.
