Introduction
Rubber stopper is usually used to seal bottles, laboratory flasks, and medicinal containers, etc. A rubber stopper is a tiny, little piece of rubber, designed like a cork (which is made up of wood and also used to seal bottles). Rubber stopper is better than wooden cork because wooden cork can be damaged while rubber stopper is durable. There is no chance of spillage or damage when we are using rubber stoppers to seal different tubes, flasks, or other glassware. Companies, who manufacture rubber stoppers, design rubber stoppers in different sizes and colors to differentiate.
Material
Rubber stoppers are made up of rubber as the name indicates. But this rubber is not the usual type of rubber. It is the hard rubber that is processed chemically. Mostly, the following materials are used in the manufacturing of rubber stoppers:
- M35 Green (Neoprene) (it is used for the rubber stopper which is used for chemical resistance)
- M18 white natural Gum (The rubber stopper, used during food fermentation)
- Red or White silicon rubber (for temperature resistance)
- Common rubber, hardened by a chemical process
The rubber material which we use also depends upon the purpose of the rubber stopper as mentioned above. Companies manufacture rubber stoppers for different purposes in different sizes.
Size
The size of rubber stoppers depends upon their use. For example, we will use small rubber stoppers for test tubes and large rubber stoppers are used for flasks. Mostly these sizes are available commonly:
- 7mm
- 15mm
- 17mm
- 20mm
- 56mm
- 50mm etc
All these sizes depend upon the specific use of rubber stoppers.
Top 5 uses
- In Science laboratories
Rubber stoppers have important uses in Science laboratories. They are used to seal test tubes, flasks, etc containing different solutions, specimens, and chemicals. Rubber stoppers prevent any spillage and waste of chemicals.
- In Industries
Rubber stoppers are also used in industries to seal large bottles containing chemicals etc. They are also used to cover bottles while extreme heating etc. Chemical resistant rubber stoppers are of important industrial use.
- Commercial use
Rubber stoppers are also used commercially and in flour. They keep the flouring intact and also used to fix some board on their place. They are also used in furniture to fix the parts of any furniture.
- Medical applications
Rubber stoppers are used to seal medicine bottles and jars in Pharmacies, so we can say that rubber stoppers also have used in medical stores.
- Machinery
Rubber stoppers are of different sizes as mentioned above. Therefore they are also used to keep some parts of important machinery intact. They are used to avoid unnecessary friction.
