Silicone Stopper Chemistry

Many industries around the world heavily rely on rubber stoppers. These small rubber products can be found at the ends of the pipes, at the top of Erlenmeyer glassware, inside of panels and heavy machinery, and so on. But also, pretty much every household owns a device or a piece of furniture with one of these inserted someplace. However, there is one particular industry that really benefits from rubber stoppers, and that is the chemical industry. You could literally pick any chemical lab or a facility in the world, and we guarantee you will find hundreds if not even thousands of rubber stoppers. More precisely, you’d find a silicone stopper. For a silicone stopper chemistry lab feels like home, and for a plethora of good reasons.

The silicone stopper chemistry is a small rubber product that is designed and made to seal various glassware and vials in a chemical laboratory. The reason why chem labs almost exclusively buy silicone stoppers is because silicone is the perfect material for this kind of environment. First of all, silicone stops microbial growth, which is essential in an environment such as that one. But also, silicone does not react with most chemicals. For instance, you could seal a carboy with a silicone stopper even if it is filled with an abrasive liquid such as acid. Additionally, a silicone stopper chemistry is resistant to oxygen, ozone and ultraviolet (UV) lighting. 

Next up, a silicone stopper, if correctly sized, offers an airtight and waterproof seal, making sure that whatever is inside of the sealed container is completely safe from all the outside factors and influences. Finally, a silicone stopper is capable of withstanding temperatures as low as negative 70 degrees Celsius, as well as temperature as high as 270 degrees Celsius, without conducting any of the heat.
