The lab tube is a glass or sometimes plastic container, widely used in laboratories. Its convenience and the frequency of its use make it a very common object in the field of chemistry and biology.
A lab glass tube is a container made of various materials such as glass (Pyrex, borosilicate, ordinary) or plastic. This narrow cylinder with a rounded, conical or flat base is open at one of its edges. This container is used to transport small quantities of liquid products or to carry out tests by mixing them with other products for chemical reactions.
The use of the lab glass tube is mainly reserved for people working in the biology and chemistry industry. For example, laboratory technicians are required to use a labglass tube, but also biomedical analytical technicians, researchers, chemists as well as students and teachers in the health field at the university. Moreover, it can also be used in a flower shop, for food products or for cosmetics.
This container is easily transported with the help of accessories such as racks, which can transport several lab test tubes at once. Available in different sizes, glass tubes from 4 ml to over 60 ml exist according to use. The capacity to retain samples for later use is another benefit. Practical, useful, taking little space, they are also used for the decoration or cultivation of flowers and plants, and gastronomy.
In a laboratory, different tubes are used for different purposes. They are thus recognizable by their different base, according to their use:
Scientific glass tubes are one of the most commonly used items in a laboratory. These essential pieces of equipment come in a range of different sizes and shapes, but why are they usually made of glass? There are very good reasons for making the lab tubes from glass, and primarily it is because this material is easy to produce and inexpensive to use. Glass does not react with the chemicals used, so it will not affect results and readings. Although a lab glass tube can be fragile and break, they are also strong enough to sanitized and used multiple times, which reduces waste. Of course, the transparency of glass means that the contents can be viewed at all times, and it does not expand or contract with heat or cold and effect readings of volume. Tubes made from glass can also be made in limitless shapes, and they can be marked by print or by marker pen.
When it comes to using scientific glass tubes, there are some simple guidance rules to follow that will ensure the items last for a long time and the users remain safe from injury. Firstly, only use the containers for the purpose they have been designed for, not for anything else. Secondly, always give the lab glass tubea quick check for damage or impurities before you use it. Use gloves and goggles, and if connecting tubes to cork or rubber use a gentle twisting action and use soapy water as a lubricant to prevent shattering.
