In the world of chemistry, rubber stoppers have an important role, and that's to plug up materials like flasks and test tubes. If you need to have stoppers customized, then you'll want to work with a manufacturer. This relationship will turn out quality rubber stoppers if you do a couple of things.
Assess the Openings of Your Chemistry Materials
In order to create a tight seal for chemistry materials holding some type of solution, you need rubber stoppers that fit perfectly on top of them. You can get an optimal fit with these rubber parts if you think about the openings of chemistry materials you're trying to support.
How large are they and what are their dimensions? You can get help with these assessments too if you want some clarity. You'll just need to provide details on the flasks or tubes you're looking to support with rubber stoppers. Then you can get the right stopper sizes that fit how they need to for sealing purposes.
Think About the Corrosive Properties of Liquids
You might be supporting corrosive substances in flasks or test tubes that need to be capped off with rubber stoppers. In that case, it's key that you assess the corrosive properties of these liquids carefully as to choose rubber stoppers that won't break down. Instead, they'll continue providing a tight seal and keep corrosive liquids from leaking out of your chemical materials.
For instance, if you're putting some type of acid inside a flask, then the rubber stopper at the top needs to be specifically tailored to resist damage. You'll have to tell the rubber parts manufacturer about the nature of these acids too so that they can make sure your stoppers are manufactured for long-lasting results.
Make Sure the Quality of Rubber Is Amazing
The only way you're going to be able to properly seal chemistry materials holding liquids is if you verify you get rubber stoppers made out of quality rubber materials. Spend time assessing rubber part manufacturers that support these stoppers.
Then see what type of rubbers they offer, whether it's neoprene or EPDM. Finally, see how these rubbers have held up when used as stoppers specifically. You can then find a rubber material you can depend on.
Rubber stoppers give you the ability to seal off chemistry materials like tubes and beakers. If you can carefully work with a rubber parts manufacturer, the rubber stoppers provided will hold up and seal liquids perfectly.
