Tapered rubber stoppers

Tapered rubber stoppers are highly convenient small objects that are mainly used to prevent gas and liquid from escaping a container. While these small objects can be used for plenty of other applications, their use is consistent in the scientific, medical, and food and beverages industries. These objects mostly go at the end of vials and test tubes to effectively seal off the substance inside. This is made so that contamination is prevented and scientists, researchers, and testing clinics perform tests more effectively and safely.

Tapered rubber stoppers can come in numerous shapes and sizes, although their shape has to be consistent with the type of container they’re supposed to seal off. Because of that, they’re mostly rounded. As for size, it’s really down to the needs of the customers. You can order a tapered rubber stopper in any size so long as you know the dimensions. If you’re struggling with that, we can help you determine what size works best for you. Considering that they are indeed made from rubber, that gives the object a set of properties. For starters, rubber is excellent for sealing off containers as its anti-slip properties will make sure the stopper stays fit and prevents any movement. This means you will effectively seal off various types of containers without any problems.

Another great advantage to using rubber stoppers is the fact that they are 100% water-resistant. That in combination with the more effective sealing means water will not be an issue during testing,. If you do happen to get water onto the container, the tapered rubber stopper will make sure the water doesn’t get inside the container.The anti-vibration and excellent heat property of rubber do have their advantages. Even better is the fact that we make our tapered rubber stoppers to be 100% chemical resistant and impermeable.
