The glass test tube used for chemical work often leaves conventional laboratories for uses such as food packaging or floral and decorative art and craft. The smart process of glass manufacture allows it to withstand shucks and thermal degradation or acid solutions, which makes it an essential tool from a health and safety point of view.
With a cylindrical shape and a capacity ranging from 5 ml to 2 l, a glass test tube can be graduated or not depending on its use. For example, in laboratories, it is used to measure volumes of liquids or gases to the accuracy of 0.5 ml. The glass test tube is the basic tool of the chemist. For safety reasons and for an intensive use, choose a borosilicate or soda lime glass from a wise mixture of boron, oxygen, sodium, silicon, potassium and aluminum. All these components make the top quality of our glass test tubes.
The glass test tube is not exclusively reserved for chemists. The use of plastic, which is a derivative of petroleum, is submitted to a greater thermal degradation. In the food industry, the direct effects of this chemical degradation on the content and, consequently, on health, are a great source of concern. The glass option is increasingly obvious to contain cosmetic ingredients, spices and sweets that are enhanced in our cylindrical themed tubes.
The benefits of glass test tubes are numerous and focus mainly on the quality and reliability of the material for all scientific, industrial or artisanal uses. Whether borosilicate or ordinary, glass can generally withstand temperatures above 500 ° C and offers good resistance to acid solutions and solvents. However, only borosilicate glass can withstand flames during specific experiments.
There are different types of glass test tubes and an indefinite number of options of use. For example, we can mention the flat-bottomed, round-bottomed, or conical-bottomed test tubes, of which some are used in centrifuges. The test tube can be customized. Their thick and transparent walls are perfectly suited for cultivation tests, seeds storage and other experimental plantations protected from insects and dust, and above all under the control of users.
