What Is A Rubber Stopper Used For In Science

As the rubber stopper is used in many experiment some specific experiment.

What is a rubber stopper used for in science. A rubber stopper is a small tapered plug used to seal the openings of test tubes flasks and other laboratory glassware. Some lab work requires a full setup of glassware. The easy answer is to cap test tubes and flasks the real answer is rubber stoppers are used in the lab because the rubber in them is unaffected by most chemicals and unlike the glass. The straight sides and round bottom are designed to reduce mass loss when pouring and also make them easy to clean.

A laboratory rubber stopper or a rubber bung is mainly used in chemical laboratory in combination with flasks and test tube and also for fermentation in winery. A common every day example of a bung is the cork of a wine bottle. These sturdy plugs fit tightly into test tubes or flasks to prevent chemical leaks and spills. We stock popular sizes of beakers flasks graduated cylinders bottles and vials.

Look no further for laboratory glassware. Use rubber stoppers and lab grade corks to contain liquids in test tubes and flasks. Generally in laboratory the sizes of rubber stopper can be varied up to approximately 16 sizes and each of it is specific to certain type of container. Keep your chemistry experiments clean and safe with rubber stoppers.

No minimum orders and we offer case discounts. A glass stopper is often called a ground glass joint or joint taper a rubber stopper is sometimes called a rubber bung and a cork stopper is called simply a cork. Our customers are not only the scientific community but also hobbyists artists schools and universities. Test tubes have clear glass to allow monitoring and observation during an experiment.

Bung stoppers used for wine bottles are referred to as corks even when made from another material. A test rubber stopper is used to close the tops of test tubes and flasks it s like a cork to close off narrow mouthed things like bottles test tubes and flasks except it s made of rubber and not. However rubber stoppers are preferable for applications that require a tighter seal or a greater degree of chemical resistance. Use this guide to identify the appropriate rubber stoppers or corks for your chemistry lab needs.

Stoppers made of cork are also available for this purpose.
