Different Characteristics of Rubber Stoppers

If you are in the market for rubber stoppers and want to learn more about them, you have come to the right place. This post takes a look at the different characteristics of rubber stoppers. By the time you are done reading this post, you will know everything that there is to know about them.

What Is A Rubber Stopper?

Before we take a look at the different characteristics of rubber stoppers, it is important to know what a rubber stopper exactly is. In the simplest of words, a rubber stopper is a tapered plug that is used for sealing openings in flasks, test tubes, and other laboratory items. There are also stoppers that are made from cork. But, rubber stoppers have become the most popular option due to their characteristics.

Purpose of Rubber Stoppers

Rubber stoppers tend to have a cylindrical shape which allows them to prevent liquid or gas from escaping the container during scientific experiments. Moreover, rubber stoppers also help prevent contamination by protecting the laboratory glassware.

Properties of Rubber Stoppers

As mentioned above, rubber stoppers are used for their properties. These are discussed below.

  1. Elasticity

One of the properties of rubber stoppers is elasticity. They provide a great deal of elasticity which makes them suitable for a wide range of activities. You will be impressed by just how elastic a rubber stopper is. It is due to this reason that rubber stoppers can be stretched by as much as nine to ten times its original length. When it returns to its original length, it will not get affected and will maintain its elasticity. A tight seal will be formed against the glassware because of the elasticity.

  1. Chemical Resistance

Another characteristic of rubber stoppers is chemical resistance. You can use them for their incredible chemical resistance. The chemical resistance enables us to use rubber stoppers without having to worry about our safety. You do not have to worry about corrosive or reactive compounds as the impermeability prevents such compounds from escaping.

  1. Strong and Tough

A characteristic of rubber stoppers that you cannot ignore is strong and tough. It is quite impressive just how strong and durable they are. This allows them to be used even in abnormal conditions. You can continue to use rubber stoppers without having to worry about them getting easily damaged.

  1. Resistance to Wear and Tear

As scientific experiments involve a wide range of temperatures, rubber stoppers are the way to go. They can be used in 7 to 155 degrees Celsius. The stoppers will not wear and tear as they offer a great deal of resistance. The same goes for abrasion which they can easily handle. The synthetic of the rubber is also resistant to petroleum and acid products.

Conclusion

Rubber stoppers serve multiple purposes. Their properties enable them to help us reach new scientific conclusions. There are many advantages of using rubber stoppers. Hence, it is best that you opt for rubber stoppers instead of one made of cork.
