Rubber stopper test tube

A rubber stopper is a convenient small object that is used for stopping gas or liquid from escaping test tubes. Rubber stopper test tubes see their uses in many fields, but none more than the medical and scientific fields. The thing that makes them so vital for test tubes is the fact that they are made specifically to fit them. With a rubber stopper, we can prevent costly mistakes and make sure the material doesn’t escape the container. In many cases, this is the number one use. 

Another use for rubber stopper test tubes is for preventing contamination with the gas or liquid. Since these samples are probably highly important for testing, the last thing we want is something to contaminate the insides of the test tube and potentially put the test results at risk. Since the rubber stoppers perfectly fit the test tube, they make sure nothing escapes or enters the tube. This gives medical experts and scientists the ability to shake or mix solutions without spilling or contamination. 

When we talk about specific rubber stoppers, we have to figure out the size and shape of the test tube. Luckily, we make our rubber stoppers based on well-known tube shapes and sizes. You also have the option to pick your own shape and size to fit your specific needs. 

Among other unique properties of rubber stoppers for test tubes, we have to mention the fact that the material used in the making of these stoppers is 100% water and oil-resistant. Not only that, but they are virtually resistant to every chemical. This means they will make sure the chemical in the test tube stays there without having the possibility to escape. The unique resistance properties of various rubber materials like silicone and NPDM is precisely why they are heavily used with harsh chemicals and in harsh environments.
