Types of Rubber Stoppers Used In Pharmaceuticals

When it comes to rubber stoppers in vials, there are several different types that are used in the industry. Each type has a different use and will be found in a variety of pharmaceutical settings.
 

Red rubber stoppers are typically found in a laboratory setting where the development of the medication would be taking place. The most common use for this type would be in a test tube where chemicals are being mixed together. This one is created with natural rubber like MWRCO produces.
 

Neoprene stoppers are created from a synthetic type of rubber that has a higher heat resistance over other types of materials. It is typically utilized in tubes or vials where petroleum-based oils are in use to help prevent the breakdown of the stopper itself.
 

Translucent stoppers can withstand a variety of temperatures and will be found in various tubes and vials.
Rubber stoppers come in a variety of sizes, shapes, and types of rubber to assist with the task they are used for. The rubber material and construction of the stopper will determine if it is used for high temperature needs or can withstand cold temperatures. For example, some medications such as insulin must be kept refrigerated. The stoppers used in these vials must be able to withstand the swings in temperature as a vial is put into use.
