Basic Facts about Test Tubes

Researchers, chemists,and scientists need and use a variety of tools to perform experiments. When they work in laboratories, it is important tohave tools that are both useful and durable. The tools and lab equipment vary with respect to functionality and complexity. Nevertheless, all lab equipment is of scientific importance. They carry value in every experiment. Basic equipment like test tubes istypically cheap. And, the test tubes are used regularly. This is why you should understand and use test tubes better.

What are test tubes?

By definition,test tubes are small, slender containers. They are designed to hold and carry liquid. Most test tubes are designed to store, and transfer samples. This piece of equipment makes life easier and faster for researchers, scientists, chemists,and students. Glass tubes used in scientific experiments come in different sizes and shapes. Most of them range between 50 and 250 mm in length. They can vary in thickness too! In most cases, the test tubes range between 6 and 10 mm in thickness. With respect to width, the test tubes range between 13 and 20 mm.

Test tubes are made of two different materials: plastic or glass. And, specializes in selling glass test tubes.

Unique Qualities of Glass Test Tubes

Glass test tubes can be made of soda lime or borosilicate. Borosilicate glass test tubes can handle heat-up situations easily. This can be attributed to its low coefficient of thermal expansion. Low thermal coefficient increases the amount of heat borosilicate glass test tubes can handle. You can subject the test tube to extreme conditions and not worry about cracking!

Test tubes vary from one another in terms of unique characteristics. Test tubes are designed with a mouth or a lipped opening. On the other hand, some test tubes have flat openings. Some borosilicate glass test tubes are designed to allow stoppers and corks. The corks and stoppers can be placed in the opening of the test tubes with solutions that are ready for mixing and storing.

Moving on, borosilicate glass test tubes are believed to be re-usable and washable. Of course, you may come across test tubes that can be used and thrown away. These are qualities that differ from one test tube and another.

How to choose the right test tube?

It is important to choose the right glass test tube for your experiments. And, picking the right test tube can be a daunting process.

Here are few tips on how to choose test tubes for your experiment:

  • First of all, you must be aware of what the experiment is all about. Does it involve harsh chemicals? Does it reach high temperatures? If yes, you must opt for borosilicate glass test tubes.
  • Are you looking for test tubes that can stand by itself? Do you want test tubes that can be stored away easily? If yes, choose the Falcon test tubes. These test tubes are designed with “plastic skirts” that can stand upright without any support.

Test tubes need special racks that can carry them without any hassles or tussles.
