These items are small and easy to set up, but they have a number of useful roles, which is why they are used in a large number of different industries. One of the industries in which silicone stoppers are most often found is certainly chemical, as these attachments are desperately needed to perform various chemical experiments. They are made in a conical shape, so you can easily seal the openings on laboratory vessels such as beakers, test tubes, cups and others. Placing these stoppers on top ensures that liquids and gases do not leave the vessel, and also that the desired atmosphere is preserved in order to achieve a certain reaction.

The best part about these silicone stoppers is that the material from which they are made is completely safe, of high quality and does not enter into chemical reactions with the containers or their contents, which is crucial in laboratory conditions. Silicone is also resistant to various mechanical and physical influences (such as extreme conditions of temperature and pressure), which ensures that it does not change, regardless of the reaction conditions.
