Rubber stoppers with holes

In each laboratory, you can find a multitude of laboratory utensils, devices and tools that contribute to the proper performance of scientific experiments and obtaining results that can sometimes be of great importance. That is why it is important that each laboratory is equipped with basic accessories that will facilitate the work of the laboratory assistant. The rubber stopper is one of the tools that has practical use in the laboratory. It is a cylindrical attachment that is placed on the opening of a test tube, bottle, vial, glass, or other laboratory vessel.

They can be made of cork, but rubber stoppers are much more common, because their application is more practical. They provide a higher degree of sealing, and rubber is also a more chemically resistant material, so it is more suitable for this purpose. The main role of rubber stoppers is to prevent the spillage of liquid from the glassware during shaking, as well as to prevent the release of gas, which is important when performing the experiment. They can also prevent contamination with toxic gases that develop during these processes.

Rubber stoppers can be manufactured without holes, but rubber stoppers with holes are also used for various purposes. These two different types of rubber stoppers are used in different experiments. For example, rubber stoppers with holes are useful when it is necessary to insert a thermometer or other tools that are important during the experiment. By using rubber stoppers with holes, the thermometer will remain in place even after sealing the laboratory vessel in which it is placed. If rubber stoppers with holes are not available to you, you can drill the holes yourself with appropriate tools, such as a cork drill, and continue your experiment without interruption.
